Bob delivered a new block to us at Thompson this weekend!
It looks great! It has billet steel four bolt main caps and everything is built very strong but as you can see from the photo's it's quite a bit lighter than a factory block.
Bob also had a new iron block there but you won't see him carrying that one by himself.
We got him to build this aluminum block with BBC sized mains and cam tunnel. It's also drilled for a BBC pan and front cover. He can machine them to take regular 348/409 components but the BBC stuff works better for us.
We're not sure how many cubic inches we'll end up with. I think it might accept a 4.40 bore and a 4.25 crank will fit easily. That would give us 517 ci. Anything in that range will be fine for us.
The iron blocks will take a bigger bore, at least 4.50 but maybe 4.60 which would be good for 565 ci using a 4.25" stroke.
We'll use this block to build a new engine for the Pontiac. I'll start a build thread on that as soon as we get started. The plan is to have it ready in time for next years race season.
