Well here is the deal i got a new engine(stock block) and am debating before goin to the dyno if i am geting a tweecer or having the dyno shop tune it. But i always like the hp guessing game so i throwing it out if anyone want to take i guess id like to see what number you guys think, I will just list actual engine components. I am hoping to hit 300 rwhp with a good tune on just engine. What do you guys think?

I see bigger heads & intake than the typical stock block combo.

If that cam is matched well to the heads and the cam & heads are matched well to the intake, I can see how you could do better than the typical results. :D

You might be better off with some race type headers which have 1 3/4 tubes and not the street type ball & socket collectors. :shrug:

24's could very well be close to the limit if you put up the good numbers. You may have to raise the pressue somewhat. :shrug:

The tune is gonna need to be pretty close for some non typical results.

I can see how you might be closer to 350 than 300 if it all matches up well to each other.

Good Luck :)
