The crane cam is in the car and what a cam. Has lots of low and midrange punch to it and a great rump rump idle at 850-900 and more cam sound at 600. The GM 260 hp crate motors are advertised as being 8.5 cr but several tests in some car mags said that the measured cr was 8.0 to 1 so this is why I needed the short duration 218 specs that has a shorter intake close point to keep my bottom end from being soggy. Very nice cam in my opinion. I have talked to some buys that are running this cam in 327's and 350's with 3.08 rear gears and stock converters. The 106 Lsa works very well and this same cam is also advertised as an oval track cam for low lift rules-.450 lift on this cam so I did not even have to change springs.
