360 or 440 in my 68 Cuda?

You can do it pretty easy. The only thing you need to do is clearance the block for the rod bolts. They sell kits or you can assemble your own like I did. I bought everything separate. I went with the steel crank instead of the (cast) steel crank. It was about $400 more but I think worth it. If you are gonna push it 600+ HP get the steel crank. You can run high 10's low 11's with ported J heads. Scotty does! Actually his J heads out flow my E heads a tad. Basically your looking for a rotating assembly and everything else will work. I did mine for $2500 labor included. I got a good deal on the labor and parts though. Going 440 will be a bi$ch. Way to much screwing around. You put the juice to a stroker and you'll be plenty fast.
