I just picked up a 1973 Nova to swap my 5.3l and 4l80e into. The engine has the BTR / LJMS Stage 2 cam and supporting valve train. Rings gapped for boost. It was in my 4th Gen with HSP V1 Turbo kit.

My goals for the car are 500-600whp on pump gas.

I am looking to put my Precision 7675 CEA on it. Has anyone found a hot side that works with minimal effort? Hooker?

What about swap mounts? I was thinking about the Hooker / Holley mounts.



​

 

The Hooker swap mounts work great, I did a build on a 74, it's on here (https://ls1tech.com/forums/forced-induction/1882541-nova-going-under-knife.html) also doing a 73 now, but LS/Procharged. 68-74 nova's all the same basic conf.

 

Link does not work.

 

I have heard there are better mounts out there, but them offering it as a kit makes it seem like you'd have better luck with the engine and trans mounting being in the correct location.

 

I'm running Dirty Dingo mounts, slid my engine back an inch. (1967 Camaro).

 

Did you have to use a special transmission crossmember to meet the trans 1" back?

 

I bought one of those repro TH400 trans mounts from one of the resto places and my buddy worked the mount a bit.

 

What did you use for your hot side on the Camaro?

Bolt-on, and TUNE.... Turn up wastegate, and TUNE some more.

 

My buddy built my hot side with truck manifolds that are v banded.

 

I sent Jon an email to see if he'd share information about his truck hot side.

I don't think there's a shot at my 4th Gen HSP fitting in there with how little room there is between the 307 and radiator now.

 

We could run a setup like that on a 4th gen but I think it won't fit in a 67-74 Nova/Camaro. I'm running truck spacing for accessories so F-Body spacing would tuck in a bit more but even with my engine set back an inch you can see it gets tight, and I have a Rhodes core support too.

My crossover is nothing crazy.

 

i used ICT plates with moroso solid mounts and pads.
Vbanded truck manifolds and 2.25 SS tube much like Johns photo above with the exception of the small pipe using 1000 pie cuts or should say death by 1000 cuts. Never again.

 

Pie cutting is a flex lol.

 

My Nova manifolds look just like John’s.
I used Corvette spacing on the accessory drive. But used the Holley PS/ALT bracket.
Novas are pretty flat in the front.

 

I am going to look into some of the guys who sell bolt in Hot Sides for simplicity and to get the engine in the car and drive able more quickly.

Looks like JP Fab offers a nice kit.

 

That reminds me, there is a guy in PA who has built to order 68-74 Nova LS turbo kits: John Potucek

I think this is the route I am going.
I am not a great fabricator so something like the hot side is not in my wheelhouse. I want to keep momentum going on this project once I start and I think his solution being bolt in will help with this.

 

Cool tell 'em John Ryan sent ya lol. A buddy is local to him and has seen two of his builds, said they were good welds.
