Because I decided to shoot for 300+ hp, I've been trying to find out more about the porting and polishing, and the cam. I've been convinced that the best way to find out exactly what areas need this is to cut the block apart! So, we are going to cross cut up a block, to identify how to get the maximum from it. I'll post pics, because I think this will be a cool learning experience. One of the problems presented by the cam is the position of the lifter blocks. There is not much room, before the lifter blocks are contacted. To go high lift, the blocks need to be modified. The other problem is getting a core blank ground, because of the cam gear cast into the camshaft. Right here, I need to say thanks to Pete1, and Bored&stroked! I really appreciate the direction and advice! Joe Panek (http://www.roto-faze.com/, knows how, and can make the cores. This guy has history, contacts, and knows what he is doing! Mostly, though, he is a really neat guy to talk to, and very, very helpful. Check out his 1936 supercharged V-12 Cad in a 34 Ford at the above link! He cuts the gear and back section off of a stock cam, and presses it into the new 8620 billet core. Guarantees there will be no issues! In addition, he knows these motors. Told me right away that the 1.375 diameter of the cam was not needed, and that he would make the cores at 1.25. That's .125 extra lift out of the gate. I was worried about having to modify the lifter blocks for clearance with the extra lift, but this helps out tremendously. He also told me not to worry about the crank. He said the rest of the motor might come apart, but a billet crank would be a waste of money on this build. I talked to Ross Pistons, and they will do the forged pistons. So, the next question- Will the head gaskets hold 14lbs boost, or will I need to o-ring the heads and block?
