Need help with a Lt1 355 build My '96 Camaro has 170k miles on it and I've been autocross it every month for the past year and a half so I think it is time to rebuild the motor. I ordered a rebuild kit out of Summit with forged pistons. I also want to do some mods to it, but I'm not sure what to go with. My goal is at least 350hp.
Block bored to 355ci
Port and polished heads
Port and polished intake
Magnum roller rockers
Magnum pushrods
Beehive valve springs
Compcams 305 cam
BBk 58mm throttlebody
Pacesetter longtube headers
K&N Kit II CAI
ASP 2 piece underdrive pulley kit
Will this get me close to 350hp? Are there any better alternatives to the parts/brands I'm thinking of getting? Anything else I might need?

Two things I'd look into changing though, first is the pistons in the rebuild kit, I don't know about the quality of the pistons in that kit, I'd try to ensure the quality by getting some Mahle forged pistons.
Second thing I would do is to go a little larger on the cam. I'd look into getting Ai 226/234 cam w/ their ported heads.
I'd also get some ARP rod bolts installed when you get your stock rods reconditioned.
Oh, get Pro Magnum rockers, not Magnum rockers.
1. Who is porting the heads? 2. only open up the intake for a 58mm tb. I wouldnt put anymore money into it because it could be better spent elsewhere.
Ditch the ASP pulley, that 150 could be better spent.
On the CAI, i would go with a used one, or cut up the radiator support a put on a used LS lid and FTRA/SSRA. The gains will be much better than the K&N CAI. Or if you go used try to find a K&N, Moroso, ETC, used for $100.
Go with a AI or LE custom cam, it will blow that cc305 out of the water. That cam you picked out is very old.
If you autocross you want the rotating assembly to be very light, why the heavy forged pistons?? You get away with some cheap hypers that will handle you racing. You could even hit a 100,125 on them if you tuned and set up the motor properly.
I would spend more time on research on the build and hopefully you will get much better Bang for your Buck.
Please give more info on goals, budget, and who will be doing that work to the car.

This is the kit that I have.
The machine work is probably going to be done by a local shop. I know I could send everything to be done professionally or better yet buy an LE setup, but I just don't have enough money to do that.
My budget to rebuild the motor is about 2500. I've already spent 600 of it on the kit.

You still have to buy new gaskets, new bolts, fluids, etc.
That leaves you NO money to buy a cam, port the heads, or even get any bolt-ons...

You really dont need ported heads to reach 350whp
Like somone else said pick up a AI cam that should get you what you want.
Id also up the compression in this motor a bit depending on the cam your going with since it will be a 355.
