1969Cutlass

Thanks for all the tips! I'm gonna play around with some scrap i have today and see what I'm up against and depending on how far I get i might start on the hotside.

interested on how your going to do the mounts. ive got a 77 cutlass im about to pull my 455 and toss in my 6.0

1969Cutlass

I was going to use the adapter plates and SBC mounts since I already have SBC frame stands in the car, but no luck there. Didn't fit . So, I'm just gonna cut and drill some plate to bolt to the crossmember, and another to bolt to the engine, and then weld some square tube in between and just put the motor where I want it.

So, I've been a lazy sack of crap lately plus I'm having welder issues so not a lot has gotten done. I mocked up the hotside, decided to run it ***** out thru the hood, and started on the hotside until the welded decided not to feed properly. I also bought all my fuel system stuff.

Mock up and hotside started.








Then I ripped the rest of the HVAC stuff out


Then I had a big hole to fill


So I got creative




Heres my fuel system. 95 Caprice gas tank, Aeromotive 340lph pump, Summit Twist Tite push lock style hose, and then 4 quick disconnect to AN fittings to slam on the fuel rails and fuel sender.

Tank got here yesterday








I also figured out my intercooler routing. Should be fairly simple. Hopefully I can borrow a welder soon and make some progress on the mounts and hotside. Until then I'll throw the fuel system together.

1969Cutlass

Still don't have a good welder, nor am I a good welder, so! fuel system. Unpacked the Caprice tank


This was a goddamn lie, that tank was not empty lol


20 gallon capacity, EFI, won't rust, all for $160 to my door. Awesome.


Old tank out.


Gotta cut the trunk floor for the sending unit of the tank. Gonna start on that if my janky jigsaw decides to work. Then gonna run down to home depot and get some steel strap and make new tank straps. I also realized I needed some 90 degree push lock fittings for the sending unit because straight fittings would put the hose right into the diff, so I ordered those tonight. Hopefully they'll be in around the time I get the tank mounted and hoses ran

This is of interest to me as I am restoring a 71 convertible and have an LH6 and the same turbo. I can get 4L80s for $250 around here so that's what I am going with.

1969Cutlass

Wow I've been super lacking in updates. Since I last posted I've gotten the caprice tank in with the AEM pump in it, hoses ran, tank straps made, engine mounts made, and the hotside is most of the way done. So hold on to your hats, heres a shitload of pics. Fair warning, if you haven't caught on yet this is a sloppy inspired build so I'm not going for beauty here. If it works and is cheap, its done.

This hurt a little. 50 years his trunk pan made it without some idiot blowing a hole in it. yet here we are


Clearance, Clarence.


It slides up there once you trim the bottom inside lower edge of the frame rail where it juts out for no good reason


Home Depot drilled flat stock. Same thickness as the stock tank straps but wider so I figure its solid.




Other one went together real quick


Oven pan HVAC delete


Pan clearance, engine mounted


Stock truck accessories clear including PS pump pulley!




Now the part I had no previous experience in, hotside fab.






mocking up the crossover and first V band


Crossover pipe and all the V bands and everything mocked up and tacked






Finish welded part of it tonight before dinner, still need to mock up where I want the wastegate and add that in


Had to slam this guy on and enjoy it






So, now you're all about caught up. it'll be pretty warm tomorrow so the weatherman says, I'm gonna try and get the hotside finish welded. I'll update with pics of the progress, of course.

Hell yeah dude. Choo choo noises right around the corner

1969Cutlass

I sure hope so

Still need to place another order for parts. I invested in a flip car in the meantime, hopefully will have that thing sold tomorrow for a decent profit. Then I can go nuts and order the $800 or so of things that I can think of that I need to finish the car (microsquirt, wideband, sensors, relays, fuse box, hoses and lines, bits and bobs, doodads, ect).

1969Cutlass

Another late night update. Had some distractions the last couple days, but I got the hotside all welded up except the wastegate flange. I also drove all the way down to Connecticut (I'm in NY) to grab this Z32 300ZX 5 speed along with the starter, shifter, and an aftermarket 1 piece driveshaft for a great deal. These are good for far more power than a T5, and an adapter kit (plate, flywheel, bolts, bushings, ect) to put it behind the LS motor is around $600. Then its around $550 for a clutch rated to 715 ft lbs. I can have the driveshaft cut down to fit my car and I'll probably run an F body master cyl. But this is for later in the year, I don't have the time or funds to make this happen in time for dyno day.

Anyway, pics!

Looking good my dude, that bend in the exhaust on the driver's side is hella sick

1969Cutlass

Yeah believe it or not the auto parts store doesn't carry 30 degree bends

I can't wait to heat wrap it.

Quinn_510

Aw man you're gonna cover up that beast? btw did you have any clearance issues with the exhaust manifolds turned backwards or did you just flip them up just cuz? I've got a 72 Chevelle I'm just curious if **** got in the way for you

1969Cutlass

Yeah I really wanna try and keep under hood temps down as much as possible. Kinda pointless I guess since I won't be running a hood, atleast not for a while. Forward and up was the only way the manifolds would actually fit in the car for me with the flanges still on them, IE if you're gonna run naturally aspirated and keep the manifolds on stock orientation like they came on the motor out of the truck, the flanges will not clear the frame. Forward and down the flanges also hit. I believe if you cut the flanges off and just welded some pipe on or a V band you should clear pretty much any way you want it though. I put mine forward and up because I wanted to keep the stock truck power steering pump in stock location, and forward and down would not have cleared the PS pump. My motor is bolted to a TH350 which is in the stock location on the stock crossmember, and the engine is centered within 1/2 inch in the engine bay for reference.

Quinn_510

My plan was to have the manifolds forward, cut the flanges and just weld new pipe, but holy **** looking at the pics I didn't know the PS pump made things so tight, thanks for the info!

Good luck with your build my dude, hope you make it to dyno day!

1969Cutlass

If you go manual steering you can do that, and I considered it, but I've driven this pig with out the pump being turned (no belt) when it had the SBC and I didn't really wanna give it up for this build

Btw thanks man! So far I'm on schedule for DD. I've got 3 other friends busting *** to get their cars ready for it too.

Quinn_510

Yeah no PS would be a bitch in the city. I've still got a ways to go from getting the motor in my car, I wish I could get it ready in time for dyno day, and its the waiting 3+ days for parts that's a real time killer lol. Right now I just gotta figure out what I'm doing for motor mounts then its just a matter of a weekend(s) of getting the motor in. Hopefully everything would at least be in the car by then but I don't think it'd be tuned and ready for icecream burnouts lol

1969Cutlass

Alright! another update. Lots more done since the last one. I mounted the intercooler, trans cooler, ran trans cooler lines, finished the cold side piping, bought, received, and mostly wired the microsquirt, still need to run all the wires thru the corrugated harness stuff so excuse the mess. And I need to hook up things like switched positive to the relay for the main fuse block, and the tach and 2 step wires on the micro. I also bought some Nascar blue streak spark plug wires to clear the flipped manifolds as per the sloppy wiki. $39 shipped one race on em, can't complain! Picked up a starter and alternator, threw those on, basically I'm fluids, driveshaft install, and some misc wiring away from firing the car. But I still need a radiator and wideband and a few other bits and bobs (downpipe, ect) and I need to go ahead and throw a wastegate flange on my hotside and mount the wastegate.









The nascar plug wires

looking good. getting close.

i've been looking for one of those rs5r30a gearboxes for awhile, they are hard to find these days!

1969Cutlass

Thanks! Yeah I'd love to hear it run this week. Also, yeah they are kind of uncommon which is why I bought this one when I found it even though I'm like $1300 and like a year away from making any use of it in this car . A friend offered to trade me a 4L80E for it which is a real tempting offer but I really enjoyed when this car was a stick last year

1969Cutlass

SO! Big update. I've been really behind on updating this thread now working full time and trying to get this car ready ASAP. It runs, it moves. Its mostly done. Lots of tuning left to do it runs like *** but atleast it doesn't knock lol.

EGR block off


New trans pan and the fancy blue moroso gasket everyone rants and raves about, I've had fluid in it for a few days with no leaks, so far I'm happy, it somehow leaked without any fluid in it with the last pan and gasket lol.


Theres 2 systems on this car I spent decent money on. The cooling system and the fuel system. Champion 3 row aluminum rad and dual 14 inch fans


shinyyyyyyyyy




Whipped these up in a few minutes with just a drill, hammer, and unmounted vice eyeballing it. so not too dissapointed with the finished product




I cut the O ring steering box end of the stock silverado hose off, and then slipped a flare nut over the line and flared the line. Slammed it in the box, rock and roll $0 spend


Rad in, hoses hooked up, fans done, oil feed and return for the turbo done, downpipe welded up ect


Rolled it out for some pics!




Picked up these seats at a swap meet for $30. no idea wtf they're out of but I like em and the price was right


One of em, and the ratchet shifter, installed in the car








I'll upload and post the vid of it running tomorrow, its late and I've got work in the early AM.
