Racers look here to help a newbie -Thanks

Rick--I'm stuck on that one too,I have several 400 blocks and also have another 5.7 like i've got in the duster and the 5.7 is machined and ready to go but the 400 blocks need everything,I know a 451 stroker is a torque monster but it might be too much in a little valiant (bigger slicks) and quite a few pro class cars at Norwalk were running built 5.7's down to 10.00,so right now I'm stuck on that one i also have a 78 360 block all machined and ready,I believe in getting a block and having it cleaned up right away to know if it is a boat anchor or a good seasoned block hence why I payed to do the machining on the blocks,Cost wise it really is a toss up or flip of the coin,Alan my engine guy doesn't mark parts up very much and that helps,I built my other 5.7 for aroung six grand and that's with callies crank,rods,diamond pistons,head studs,main studs,custom comp cam and lifters,indy ported big valve 5.7 heads and a pro-max 950 carb,that has 528 to the rear tires on a Mustang dyno without the 150 shot of nitrous i have on tap,I'm a true believer in the 5.7 and kind of leaning that direction but the 451 stroker might be the ticket--I'm open to suggestions--Steve
