As for cost, you will have to goggle that. Thats what i do. Find what parts and numbers needed and then buy them from the cheapest sellers. I've bought crank, rods and pistons all from different sellers before because of being that much of a price difference between sellers.

When you start getting into 4.25+" stroke cranks Cast should be avoided because the amount of webbing or crank rod journal overlap starts to be critical, even at 600 hp IF it were to detonate it could still break with no warning, your only talking a few hundred dollars more, Smitty

So i found a 454 short block at daddysos marine in pompano near me. bored out .30 with some domed piston and a stroker crank, still getting the details, but it does have a steel crank studded and aftermarket rods. When i asked him if it was a 496 rotating assembly he said know just stroker crank. So how does that compare??
From there he said he would warranty the build and throw brand new gm rectangular port heads on it,and a gm 502 cam with aftermarket oil pan. He is telling me 10.5:1 compression i told him multiple times i want a 500 plus hp motor... what do you pro's out there think..
I have a .6 lift bob m cam that i wanted him to install but he wants to stay from that and again put in the 502gm cam...... Please give me some feedback Thanks

Not saying that it is definitely bad, but heard some bad things about that place in the past.
