who runs 13sec to 12.80 in the 1/4

Adam,
The pistons aren't the only thing to making more power, they just allow the use of larger cams with more overlap to work better. Also with the smaller cam the compression in the cylinders will be higher due to less overlap, this is why I said to go with the dished pistons. So this way he wouldn't have to rebuild it later if he wanted to step up the HP, and also he would have more clearence for a larger cam. The only thing that I could see that he would have to change later is the heads and not go straight to Eddys to start with, as I think that they would be way down the road for him as he's on a limited budget. And also that the engine isn't going to be turned over 5500 anyway, at this point the eddys would be over kill and not much help with the power. Iron heads are his best bet for now, and being that he has the 318 heads I would use them to help him save money for other things that he's going to need.
