picked up my first ls1 car 2001 firebird auto
here is my build plan thus far engine wise
ls3 heads intake rails etc...
polluter cam ls7 lifters pushrods springs
arp head studs cometic head gaskets
plate kit at 175hp
3600 yank convertor
4.10 gear
275 pro series drag radial
and a real solid tune
car already has a nice fuel system and suspension on it
am i missing anything major
and what should i expect from it hp wise from my reading im guessing
420 ish on hp
600 on spray or a hair more or less
thanks for looking

 

I'd say built tranny then bye bye 10 bolt

 

This. May want to add a window switch as well, just to be cautious.

What motor is in the car now? You do know LS3 heads don't fit on an LS1 due to the valve size? I don't think the polluter cam will work well on an LS3 headed setup. You will want to get something more rectangular port oriented for the heads.

 

it says it has ls1 in it and therefore ls3 heads wont work as 87 silver bullet said.

 

It has a 9 inch in the rear. As I said I'm pretty unfamiliar with ls1 engines. I'll look into other options as far as the heads and intake go. I had the ls3 stuff already so I wanted to use it

 

Why not a cam like the ms4 or ms3 stock headed cam only 175 hit?

 

Big cam, big heads, fast 102 with TB 150 shot


I will be going with the trick flows 215cc, and a 102 I/TB i have the polluter v2.

 

Can you elaborate a little more on the fuel system?

 

1. LNC 2000 Timing Computer.
(Best Timing Retard for LS Engines...Its comes with a plug & play Harness).
Adjust this Box to Pull 2 degress of timing for every 50 H.P. of Nitrous increase.

2. Fuel Pressure safety switch

3. Window switch to turn Nitrous on a 3000 rpm & off at 6000 rpm before factory fuel cutoff...to prevent a lean condition while on the bottle.

 

Get a pair of 799 heads. They are supposed to be the best cathedral port heads for stock castings. You could probably sell the LS3 heads.
