ive just built a lt1 bored .30 flattop pistons new stock replacement rods and crank. it has the cc305 cam, long tube headers, true daul lm1s, 58mm tb, long story short full bolt ons.
stock heads only have been port matched to gasket.

its a t-56, 3.73 gears.

what kind of power should i expect from this build with a good tune? ive also been thinking about a 150 shot how much would that help? thanks guys

 

With out knowing what pistons you have I would say 320rwhp

 

you should expect people to make fun of your title....lol

350
350 + 150 shot = 450

 

the pistons are the mahle hypertectic flat tops. dont have part number with me its at the shop.

thanks i didnt notice the title till you said something.

 

im realy looking 400 rwhp out of this bottom end. i wanna change heads/intake just dont have the cash yett. whats the best heads (for the price) would this motor with decent heads make 400 ar the wheels?

 

Yes and the right compression.

 

Sorry forgot about that cam your using... Maybe close to 400

 

jason, is that 400 at flywheel with that cam on stock heads? thanks for the help its my first lt1 build

 

Sorry, you aren't going to be anywhere near 400 rwhp with that cam and stock heads. Probably in the 330rwhp range....

 

What I meant was maybe close to 400whp with a good set of heads and intake like you mentioned above.

 

okay thanks. another question is what is the max amount of nitrous do yall think this motor will hold?

 

cc503 with an M6 and a decent set of heads you should see in the 370-380 range with a spot on tune.

 

CC503 and send your heads to this man http://elliottsportworks.com/home/?page_id=51; le1 with stainless valves should put you at 400whp. With stock heads I don't see you putting down 400whp you will have to run a cam like the cc306 and I don't know if that will put you at 400whp with stock heads. Power is made in the heads so if you want power you are going to need to spend some money on the heads; lloyd will say port matching and gasket matching will not help much and it can even hurt hp, something about port matching increasing turbulence at the push rod pinch causing hp loss.

 

thanks guys. i wanted to buy some dart or trick flows then send them off is that pointless or would if be worth it? thanks

does anyone know what stroke i need tobe on tdc when instaling the hub?
or even how to tell which stroke im on?

 

Expensive but worth it for sure.
