I know this is a thirdgen forum, but I think you guys would still enjoy this video of what my car put down Let me know what you guys think

 

Really strong numbers, I have a 24X 398" motor in my 93, cars been sitting for the past year or so with a valve train issue. Great to see other LT1 cars out there.

 

Thanks man....lots of work to get to this point

 

Very strong, Any motor specs you could share? cam, heads comp ratio?

 

Factory 4 bolt main block
Scat 3.875 crank Scat H beams Diamond pistons
Advanced Inductions custom HYD roller cam
AFR 210s ported
Factory intake manifold ported by me
10.5 compression runs on Cali 91 garbage
24x torqhead swap
6speed 4.10s out back

 

Very nice and great torque too

 

Thanks guys
My plan is to get another intake manifold and get much more aggressive with the porting. Probably weld in more material to get a taller runner. Also switch to monoblade, should help with more top end.

 

Sounds great too!

 

Excellent numbers! Your car should be a lot of fun

I've seen a couple of LT1 396's fail to break 400 whp. Those had stock Optispark style ignition setups.

 

Very nice!

 

Nice numbers, congrats! I'd don't see myself ever doing an lt1 swap on a third gen, but a mid 90's car with those numbers would be a fun daily driver and surprise a lot of ls1 guys, lol!

 

VERY NICE!!!! Good to see a traditional small block based build kicking out good numbers. I am about to use the same stroke in a .060" over 400 block with 170cc Etec170s in my Vortec Express van. Its not a high reving build but I am using 6" rods. I already have the 24x setup run by an 0411 and a ported L31 marine intake on the current 350.

Whatever happen to that TBI engine you had on the van? I remember following your posts about it years back. Did you ever dyno it?

 

The engine I am building is in my Express I converted to 1-ton that I pull my travel trailer with.

My old TBI in the G-van hit mid 300s at the wheels with worked Vortecs, 2" marine TBI with 61# high pressure injectors at 30 psi (~104 lb/hr each) and a victor jr 2bbl intake. Cam was too mild and compression ratio too low for any more.

The 383 TPI replacement was in the 380 rwhp range. I still have the old G20. Has a 454/502HO cammed 8.1 sitting in it. Have the engine at a point where I have test run it but I still need to swap a 4L80E into it and convert it to 4x4 1-ton running gear. Have other projects and 70-80 hour work weeks in my way at the moment.

Its a bit of a monster sized 1-ton Express van though. 1 ton suspension with a 10.5" full floating 14-bolt under it. The Vans have the same frame 1500-3500 just different suspensions. The heavier suspension literally bolts on to them.

 

Sounds amazing
my friend had an LT1 that he let me drove man i love driving that LT1 power camaro

also car looks great

 

Pic of the engine bay. Theme is, make everything look as factory as possible.
