I greatly appreciate the advice, that’s one of the only things I don’t like about being a Mopar owner. Chevy information/parts are just so cheap and plentiful. What does BHJ stand for? Sorry I’m kinda new and don’t know a whole lot yet. This is the most I’ve ever posted on a forum and I’ve been a member of some of them going on 11 years lol. If you can point me in the direction of the butts I need to kiss I’ll get my chapstick.
It's BHJ Products and they are in California. They make all kinds of killer tooling so you can machine a block completely. They also have stuff they don't list on their site...like a fixture (a torque plate really) that allows you to correct cylinder head dowl pin location.
They also make torque plates for rough bored blocks so you can get the bores correctly finished on all axes.
But...you need the main line in first, then you machine the decks square and parallel and then you correct the bores to the blue print.
Actually, you may call BHJ and ask them about blue prints and such. If they don't have them, they may be able to hook you up with someone who can because they have them.
Interesting enough, I was on the phone with them on Wednesday and we were discussing R block head bolt patterns and he would suggest a torque plate unless you had the block in hand, to measure some things. The guy said there were different bolt diameters and such between different dates and casting runs of blocks.
So you may want to call them and discuss what you are doing. The bad thing is it looks like your bores are finished and adding 8 bolt holes per side will almost certainly pull the bores out of round. And I don't know what your finished bore size is.
So that will give you some leg work and research to do.
