[QUOTE="mna0121, post: 599224, member: 2868"] That's funny, I think your formula is wrong. Summit racing has a charts for CID, CR that you plug the known numbers into and it figures the numbers for you. I could never get it right with simple math either. I dug up the paper work from where I ordered parts from BTR. So the CID is going to get larger by JJ's math. The crank shaft is actually a K1 LS1 346 24x reluctor @ 4.125 stroke Wiseco 4.030 bore pin size are .927x 2.250 with negative 11cc reliefs and 1.050 comp height a set of flat tops here would have given us some more compression H-beam rods @ 6.125" with Calico coated Clevite bearings same for the main bearings Durabond coated cam bearings The heart beat of it all is a BTR custom ground cam shaft 238/250 .651"/ .630" 113+3 @ 50 If you are 40yrs or older you probably remember when a cam was simply referred to by its max lift? The heads are TEA's 245's TEA is the company Brian Tooley started. They build their castings and do custom work for Trick Flow and I guess anyone that needs their services. I would like to have the heads milled but don't think I will pull it apart just for that, however if I have to take it apart for any reason I certainly will have them worked on. Happy Fathers Day to all and as always Roll Tide Roll [/QUOTE]
