chevy 305 cylinder relined
i am a 38 yr. in the trade toolmaker/machinist....but am just now getting into engines. i am building a 305 trike. Problem is this----i resleeved one cylinder myself when it did not cleanup at .030 over.( i did not want to go .060 over. ok....i take it back home from the first shop with .003 left in the cylinder to hone. i take it to my shop, set it up and bore for the new sleeve. I stopped the bore cut about 5/8 IN FROM THE BOTTOM OF CYLINDER, and installed the sleeve. BIG MISTAKE I should have bored the full cylinder length! when the second shop rebored and honed the cylinder, i have about a .003-.004 step (ridge) where it did not match up exactly with the first shops cut. to sum it up...about 1/3 of my cylinder (circumference ) x 5/8 inch high (bottom of piston bore) ,does not match the other 90% of the bore. this area is on the lower skirt only, and on one side (one skirt only). do you think it's going to run? i am not close to the rings with this little step.
Any opinions greatly appreciated.
