sweatys rebuild

Recommended Posts

i hadn't noticed this until yesterday, but it looks like the pistons are right at .5mm out of the hole. this changes things a bit. i took the head in yesterday to have it checked and if everything is good, bigger valves installed. should find out next week.

im wondering what he PO had in mind when he had this block rebuilt.......

More importantly I would measure deck height of Pistons . Unless they are waaayyyy out of the top of the block I would go with what ever cam you want. I'd say with reliefs you could go 550+

The piston pop-up is normal.  About 020", or 0.5mm.  The observation crops up here and there, for stock engines.  Doesn't seem to be spec'ed out anywhere but many people see it.

this has me wondering about piston-valve clearance if i go with a higher lift cam. just trying to wrap my head around it all. sooner or later it will click

Not sure I agree with your explanation Cliff :)
There's guys running 500+ lift cams with flat tops with no issues.
Everything comes at a risk with performance parts . Things do get closer to clashing, but if installed correctly you should be okay. There are methods of measuring.
I actually shaved another .007 off my block so the Pistons are now .025 out of block- but I'm willing to take that risk ;)
