Stitcherbob, the combo he is trying to build will yield him a 451. Heres the kicker, it cost the same to build a 500 as it does a 451! IMO when spending the same dough, go with the inches, don't have to rev to get the same power and look for an average of 40+ ft. lbs. of torque. You can get away with more cam with the 500 as we all know cubes tame the cam and makes it "shorter" but this also boost torque in most cases. In STINGER's case its a little different because he already has a crank but he's gotta get the rest o' the stuff which is not a difficult task. One thing to remember with large bore strokers are they are VERY sensitive to compression. In a street car with iron heads don't shoot for more than 9.5 - 10.1 on pump swill and no more than 11 with aluminum heads. Avoid dome pistons, they hamper flame propagation, go with a dish piston with a quench chamber, much more effecient and are not as succeptible to "hot spots" like dome pistons. If y'all want I can give you part numbers, specs and proven dyno output of said powerplant(s).

Hey Stinger, try www.mopartsracing.com and look for pn 5007345 for your stroker windage tray (this is a MUST!!) and pn 5249817 for your pickup. There is some necessary grinding to the block that will ned to be done for clearance of the rod bolts and the counterweights of the crank, which by the way will need to be turned down by your machine shop as well as the oil pickup hole in the block needs to be enlarged to 1/2 from 3/8 which is also done by your machine shop.
