My ls1 chevelle build

My ls1 chevelle build Thought I'd start a thread to document my work. Should be getting started soon I hope. I've been doing research and ordering parts already...I want to do everything possible to get it in and running by the end of May.
So far I've ordered:
LS2 timing chain
Comp custom grind cam (similar to a Thunder Racing TR230/224 reverse split)
stock MAF
ported LS6 oil pump
.080 wall Comp pushrods
Comp 918 valve springs
Still need: headers, rod bolts, harness, ECM, air filter, make some custom engine mounts, LS6 intake, fuel pump, throttle cable, and plenty of time to massage this thing into the hole with the stock oil pan and acc. drive system.
Should be pretty fun when I'm done and still be 100% daily driveable...prolly even increase my fuel mileage quite a bit so long as my foot doesn't stay planted to the floorboard
Updates to come. Cam is going in Easter weekend. Also might massage the head ports, and will polish and port the throttle body.

Well I'm behind, but I have all my stuff here expect fuel and power steering lines.
Harness is 99% done.
Stock cam had a failure on 2 lobes so I need lifters and then the motor is going back together and into the car.
Hopefully the car will be close to running by the end of next weekend.

thunderstruck507 I just noticed your engine has the factory disconnect for the fuel rail. You were asking in the other thread what to get. I used the factory one. HP rubber hose from hard line with hose barb to fuel rail factory connector. I just doubled clamped it.

I'll have more pics soon.
I'm actually wondering if the harness is done right it was so easy...I didn't strip it though. I just unplugged the crap I don't need from the ECM pin out per the sticky and cut the wires loose from the 3 F body plugs I need and soldered new wire leads onto them that will go to an underhood fuseblock. I went to the salvage yard and got a OBII port for $4 and soldered it onto the harness. All in all it took me prolly 3 hours using nothing but the info from the stickies here. It only took that long because I was double checking all the info and taking my time.
Yeah I got 23 mpg from Ft Smith, AR where I filled up to my house in Valliant, OK. 30 minutes of that drive is at 45-50 mph through the Ouachita mountains too.
Street Avenger 670 with larger front jets, mild 320 hp 350, 700r4 with lockup, and 3.42 12 bolt out back.
City mileage blows though...from my house to work I average about 11mpg over the week. This is 90% babied at 45mph and 10% romping around for fun.

well just got a call from the machine shop, apparently my heads were "hangover day at GM" heads
with brand new comp 918 springs the seat pressure on several is 50-75 instead of into the 100s as it should be
it never stops around here...I should have sent my 5.3 truck heads to have better valves put in instead

I did the same thing to my throttle body. So far I am like you and have not had a chance to make any noise with my swap either. One tip, while you have the throttle body off, go ahead and pull the coolant fittings out of the throttle body if you were planning on doing the throttle body bypass mod. Grab them with some vice grips, or channel locks, and twist and pull them out.
I am in the process of pulling my harness apart to get all of those unused wires out of it. I don't want all of those wires in the harness nor the connectors on the other end. I will probably have more than 3 hours in it though.

thanks, I'm about to order another 90 elbow to go off the MAF, ditch the extension and run pipe down to the filter which I will mount low so that its about even with the sway bar under the car, this will give me tons of ground clearance but put the filter down where there's fresh cold air

I'm gonna get some, car is dirty right now...washed it then it rained.
There are older pics on my cardomain, but my roof had a clearcoat failure so it peeled and rusted, I'm about to sand it down and shoot the whole roof in black epoxy primer to mimick a vinyl top until I can afford to have the car repainted.
I'm gonna try to get some videos soon of the exhaust idling, cruising, and WOT. It's actually very tame sounding...very unsuspecting. *sneaky eyes*
