Are you guys running aftermarket blocks or original?

My 588 is a Dart big M block

Thanks for the info man. Im not going to chance busting the block. Dart were the ones I was looking at.

LOL, you would be amazed at what a stock block will handle.

Especially on boost, since boost comes on gradual it makes them last allot longer.

Zone is right a stock block will handle alot. The only reason I have an aftermarket block is cuz the guy I bought the short block from built it that way. I had a 70 something 2 bolt stock block 489 that held up to 15 lbs an never had a problem.

I had main studs installed and that's it

im pretty sure the nwer late model roller blocks can hold some power with supporting mods.
