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

reducing the compression will kill that cam, and the performance......drop the compression for the street you need to go to a smaller cam.. but with the higher comp. that cam will scream ! . try to find the original speck on the piston clearance , i would go no more than .002 more to clean it up and as stated the bores must be straight . You may be able to clean up the bores using a ball hone , they work well without removing much material. you need to stay as close to the manufactures speck as possible .



sorry ..looks like fishy and i were typing at the same time....
