View Full Version : Need tech help for an idea

September 18th, 2017, 17:06
Call me crazy but I'm adding a blower to my stroker 4.7 after the rebuild. I have the fuel dealt with. Still need spark timing sorted. It that's later. What I need help with is what ring end gap I'll need to sadly run about 8-10 lbs of boost. It's a 242 block, bored .060 over, 258 crank, cam, head ported and polished. Thanks to anyone in advance.

To sadly run that much boost? Oh, no gap at all oughta make it pretty darn sad.. ;)

Typos can be entertaining...

At that level of boost, a normal ring gap ought to be fine, really. I've known plenty of folks that run 10 pounds of boost with a formerly-NA engine without any internal mods.
