Thanks for the info, but I have already had the motor back from the machine shop. Bored +.020 and decked. I then found and ordered a set of +.020 SpeedPro coated pistons. I then had them throw in the correct rings for a package purchase.

So a 400 being a stock bore of 4.125, I add .20, and need a compressor with a final bore of close to 4.145?

Yes. Purely a guess ... SP pistons either H615CP20 or H616CP20? Next time ... best to bore-hone block with pistons in-hand ... honed to fit individual piston. Same goes for rings ... hone/finish/grit/Ra to mfg's specific ring guideline.

That was the original plan. I had dropped off the block to be bored +.030, and when I picked it up, the invoice said +.020. A called and asked what was up, and the machinist said they don't like to take more than is needed and the walls only needed that over-bore to be good again. Yes, I got a FULL refund, and then just decided to keep it the way it was.

Beats a tin can and hose clamps.

What's wrong with tin cans? Beer cans are close enough. Somewhere I have this cool pic of an engine with an intake that had 8 tubes, six inches long, going straight up. I can't recall what that kind of old intake is called. Anyway, he had bottomlesss beer cans over the tubes, I guess to keep any rain or dirt from getting down into the intake.

Must be a stack injector with 8 ram tubes...search for enderle, hilborn, crower, kinsler, algon, engler, tecalmet-jackson,...you name it..
