Alright I am going to use a 306 cam, 10306 crane spring kit, 1.6 gold crane rockers with the stock valves. I then want just the LE2 port job (all the porting may be the same, he might just change the valves I am not exactly sure) In your opinion I know you can't know for sure but do you think I can get over 380rwhp with this kit and the stock valves and the 48mm throttle body(in time I will get a 52mm). Also if I do ever get new valves, I noticed Lloyd uses ferrea 2.00 and 1.56 for the LE2 kit so if I buy these valves how long are the valves suppose to be to fit the LT1 heads. Thanks for any help.

 

Ask Lloyd, he would be happy to fill you in.

And im making around 380 RWHP thru an M6 and the LE1 package, and the CC306 is quite a bit bigger so with the LE2 heads i bet you would make over 400.

 

I wasn't sure if I would make the 400rwhp mark because I am using stock valves and a 48mm throttle body.

 

Yeah your air/ fuel might be slacking if your going to be running that cam and them heads. Will eventually need injectors as well as a 52mm or even a 58mm. Also depend on your exhaust setup to. Im guessing LT's, no cats?

 

Why do you think my air/fuel ratio will be lacking with a 306 cam and ported heads, I thought you are better off with ported heads with a 306?

 

Not the ratio, just saying your air and fuel in general. Running a stock 48mm TB and stock injectors. Needs more air and fuel. I think you will come close to 400, but when you get the additonal complimenting parts you will most likely go over 400 easy.

 

Ahh I see, yeah I am going to get 36lb injectors, guess I should have mentioned that. I will tune it again once I get the throttle body. I would love to reach the 400 mark and to go over it would be better.

 

Im hoping to hit close to the 400rwhp mark with LE1 heads, and a medium size Joe O cam. Of course with LT's, no cats, 52mm TB, 30lb injectors etc.
