Re: 1967 428 Block prep suggestions.
I agree with both posts so far.
I would go Probe or Diamond forged piston, stay on the tight side of manufacturer wall clearance, .0045-.005 is what I run on Diamonds. I also like a little more ring gap than most, and extra on the second ring.
A straight main alignment, new bore with no taper, square and zero decked (or close, as long as clearance + gasket thickness is .055 or less I am not too fussy), and a light chamfer/match for any oil galley that needs it is all I do
A good set of main bolts (stock are just fine IMO, but ARP are good too), and I like to do an oil hole chamfer on the crank before its turned (but I dont always do that either) Rod bolts I'd go ARP, but FE rod bolts don't ever really to be an issue.
Slap a good baffled pan and a CJ windage tray, and the block will be good and strong.
Keep track of all your measurements and we can figure out exactly what the compression is too.
