I'm stuck with the 75's for now, but I havn't gotten the block and related parts back from the machine shop yet. I'm thinking of going with the KB pistons that Tech had originally rec'd for this build- I've got a little time to get them so they can be hung on the rods. Race gas= $7.20 per gallon- only by the drum @ $385. Yikkes! 24gal tank= 2 fills and that aint good seeing as the stock 460 in the car is a pig on gas. The other 2 cars I was looking at for this engine are in too poor of shape for me, so it's onward ho with the land yacht LOL!
