388 is .060 w/ 3.75 stroke. .040 w/3.75 is a 385.

[QUOTE=94fixerTA;13380498].060 is not a good idea. I had a used block that I got and the machine shop wouldn't touch it cause it was already .040. He said if your panning on doing any " hot roding" goin anything over .040 is not a good idea. And I thought a 400 crank and .060 on a sbc would be a 396. So wouldn't .040 be a 388?[/QUOTE

Bore x Bore x Stroke x .7854 x 8 = Cubic Inch Displacement

Have fun.

I like to think of it this way after my experience : .020 more material removed just for 3 cubic inches? Imo sacrificing the structural integrity of the block isnt worth 3 cubes.

and im not say that your wrong but everyone gets the misconception that you cant bore these things out safely over .030 and thats just not the truth.

It's all in the core shift. Not all factory blocks are created equal. Without a sonic test you just take your chances and roll the dice. I think that is all we are saying. I have no doubt many people have safely bored .060". Hopefully Spilner will have a fine motor.

I have several because I campaign two Stock Eliminator Firebirds. You need to keep a good spare on hand for each. None for sale at the moment.
