Any one interested in the oiling mods I did?

lol that's the secret. A 400 Chrysler has a big bore (4.34 standard) and can easily go 500" and use all the usual big block heads. Why am I mentioning that? Because it is the same weight as the R3 block. I thought small blocks were also light blocks....

As for the counterbores, all I can say is these blocks were 'functional' as shipped but clearly the intention was they'd be heavily worked before anyone used them. I'm glad there are no c'bores as it allows me to do what I want in that area.

LOL...ya suckered me. The biggest issue with the 400 blocks is getting an aftermarket block that will take any power.

I’ve done several and no matter what you do the mains move around, the decks move and it makes it hard to seal the head gaskets (did a B1 deal that was a 400 block, 4 inch arm and the customer was positive he wanted 15.5:1 minimum compression and it was hard to keep the gaskets happy...his crap tuning didn’t help but that’s another story) and they just generally don’t look good when they come in for a freshen up.

If you can get a good block, absolutely that’s the road to go.

The guy who held the BB/A Comp Eliminator National Record for a while said his biggest mistake in coming out of retirement was choosing a 300ish inch small block when he could have used a high 300ish inch big block and had a huge selection of heads and a much stronger block.

That’s one of those live and learn deals.
