HOT 340 Engine rebirth....... maybe!!!!

I measured the bore and pistons and it looks as thought it was set up for Drag Racing Piston to wall clearances are .010 which is Nitrous or serious drag racing specs.

Ball park Compression seems to be 11.14 assuming a 72cc chamber, 4.100 head gasket dia., "0" deck and a .039 head gasket.

Pistons have a 10.7 cc dome and bore is 4.073.

So after I nail down the actual head cc's and find out the actuall deck height I might be alright for compression, I can even run a slightly thicker head gasket if I need to fudge the numbers down a bit.

The only thing is the Piston to wall clearance of .010, how noisy is this going to be on the street and is it advisable?

The other option is a set of KB243's and get the cylinders honed to 4.08 for a .040 overbore
