Guess top dyno
I assume I have at least 8.5:1, the pistons are flat tops and I am using .015 steel head gaskets. I have too ck on the heads. I contacted Crane about the cam because I was looking for something in 210@.050. They said the cam would work great in my combo. And that was good news for me as I bought it new off eBay cam and lifters $60 bucks. As for the ground in 5 degrees advance, it didn't have that on the cam card but I will ck in to it. I just put the long block together but still have the timing cover off. Several bushings came with the gear drive but I installed it straight up. As for the desktop dyno I think it's math is a little fuzzy. Your numbers seem pretty close to what I was thinking but all I was hoping for was a daily driver for my jeep.
