I'll send you an e-mail response with some recommendations for you. You don't want to run aluminum block in your street car - if you want affordable reliability and durability, run as much iron as possible...

Just so you know - I haven't blown you off on this... I have sent you replies to all your e-mails with detailed info and recommendations. However, all e-mails sent to you and "replied" to your address come back as "undeliverable."

I went with a 1969 350, 4-bolt main block out of a truck. Realitivly high nickle content. Cost me $100 out of Craigs list.
Bored it out to .040 over.
Forged SRP pistons.
Forged 4340 Eagle crank.
Forged 4340 "H" rods (5.7 inch)
Alum heads.
ARP bolts & studs.
Wish I could have budgeted for an alum block.

Used cores are easy to come by...

Can anyone suggest the best block to start a stroker project?
Thanks,

Many will answer your question with very expensive aftermarket blocks by Dart or World products and those are very good starting points. But for a street car, a normal old GM core can be a very good starting point for a stroker motor. It can be argued that a "seasoned" core has already done all the "core shifting" it will do and, therefore, is a better starting point. This phenomenom (theoretically) is more prone to happening on new blocks.

Depending on what displacement you're starting with, you can get a 350 4 bolt or 400 2 bolt (said to be stronger than 4 bolt, in this case) core for a couple hundred bucks and have a perfectly good starting point for a stroker motor. In either case, these should hold up to plenty of streetable horsepower and should last you years to come.

Of course, I have nothing against $3k or $4k blocks, but I think they're often overkill for a street car. Let the firestorm begin...
