Default Small update


Got the car on the ground to see how far the sway bar rolls back.


Not to bad time to install the balancer.

Old balancer on and have little ove a 1/2" of clearance

Don't think the ls1 lower alternator bracket is going to work have to search for some tight clearance brackets. Y'all have any ideas on what i can use with truck spacing?

Showing how wide the bay is.

TBSS intake sits high but i got it with rails for $190..

Looks like i might be the only ls400 thats going to rock a hood scoop lol. Hopefully this weekend i can get back to work on the transmission.. was holding off as long as i can. The empty trans case makes pulling/installing the engine so mich easier.

Put an L88 hood scoop on there. That'll throw the purists into a full-stroke tizzy!

That's who I'm probably going to use just have to come up with the right concoction so I can squeeze ac in it to. but i do like looks of the dirty dingo ac bracket looks like its really slim and snugs the compressor to the block.

It's 31 inches, I might try spacing the sway bar mounts to gain some clearance to run a low mount alternator. I have a 145amp alternator coming tomorrow so hopefully I will have some pictures to post.

29” on my Volvo - I run the low mount ICT with the 145A Escalade alt, no problems. But I dont have the sway interference issues you do.

Hopefully the small spacers I plan on making for the sway bar mount will work. I got the same alternator arriving tomorrow hopefully it's not to chunky.

I swear, the rails on yours look closer together than mine. Edit - I think it's because the rails in yours may sit higher in the unibody than mine do.

Yeah maybe it was the angle or lighting but that sway bar is being a pain. I'm having the same issue with the a/c but hopefully the dirty dingo bracket will squeeze it tighter to the block. I really like the holley mid mount setup but I can use that $2k else where on this build.

I used an Alan Groves low mount a/c for Sanden. You can see - it’s snug.

If you're moving the sway bar "down" -- will you have to open up that hole in the chassis brace that it runs through?

Yes I'm not moving it much maybe 1/2" or so. definitely not cutting the swaybar openings till the alternator gets here just to make sure.

Some parts are finally showing up. Hopefully this pictures look ok keep getting file size to big tp process so I had to resize them.



Luckly this small case alternator works. It's snug but thats also with the ls1 bracket. My ICT truck spacing brackets shoild be here soon along with more accessory drive items.

Jist glad I don't have to go this route... this was going to be a last resort Idea lol.

Still working on the transmission had order another center support bushing got the new one pressed in but needed to seat it down alitte further and this happened.

Default Question about p/s pumps

Also does anybody know if a 2004 pontiac gto p/s pump is the same as camaro ls1 pump? I got one with a bunch of brackets I was using for test fitting.

Waterpump came in, looks good with the ICT billet brackets.

Test fitting the radiator, might see if there is a slimmer option. The mk3 toyota supra radiator is replacement option for this car but this one is a 3 row and is super thick. Might limit my options on the turbo crossover options.

Looks like the hooker turbo blackheart manifolds might be my only option.

Also got the new center section bearing pressed in and managed not to fudge it up this go around lol
