340ci vs 360ci engine

im pretty sure 340's were 2 bolt not 100 percent

i know a 70 340 ta block had extra webbing. I have one under my bench i took out of my cuda and put a 360 in place for a runner.

theres an article in one of my books where they took a semi stock form 318 put a procharger on it and made a bit over 500 hp
