Alum Block Question

How good/streetable are the older Motorsport aluminum blocks? The ones with the cam drive accessory mounting.
Any special considerations that have to be looked out for?

Value compared to newer alum blocks?

Yes, close to buying one from a fellow member! Thanks for input.

I can't answer on the streetability, but as long as it hasn't been windowed, and as long as the main bearing bores haven't been run hot, should be good I'd think, if the price is right.

Steve what do you by being windowed ???

Rod out of the side of the block, Nick. Not a deal breaker, as long as it doesn't hit an oil passage, etc. We windowed an A96 block several years ago when a rod broke at 8200 rpm. Piece was still hanging on, right behind the oil filter pad. Pushed it back in place and welded it up. Still running today to the best of my knowledge.

Thanks Nevs. It is a wet block, so should be ok on the street in that aspect. Has aluminum main caps so not sure about those. Never been windowed, only minor repairs that he says never affected it running...and I believe him.

It's a bare short block (crank, rods, pistons, balancer, flywheel). Wondering if it's actually worth the asking price (says he's firm on it) because of the extensive use. Don't want to publish that here because he hasn't advertised the price. I can do PM's if anyone is wondering.

If the seller is seeing this, no offense, just some due diligence!

You can pm me if you like, I'm no expert, but I'll give you my opinion.

im runnig a old svo block alum, the main caps are billet steel, not alum, george.

Thanks, George. From what I've read/researched, you could get the old ones with either Aluminum or Steel caps. Not referring to the A96 blocks, but the older blocks that look more like this:



Is that what you have?

ive had a few of these, 2 right now, nothing wrong with them, if they have alum caps still, change them to steel
