Just a little update on my 507" Cadillac, also a very good example as to why you should degree your cam if at all possible. I was talking to Glenn Snow at Snow Performance in St. George, Utah, they are going to do the dyno runs on this engine in a month or so. He asked me if I had degreed the cam when I installed it, I said that I didn't have the wheel or dial gauges. Well he graciously announced that he would be enroute to my house after work to perform said ritual "for a beer and gas money".....80 mile round trip mind you.
This hyd. flat tappet cam is an Erson ground for MTS...Maximum Torque Specialties, 230/235 dur., 535 lift on a 112 ICL. After we did the first degree sequence using a calculator to do the math, Glenn looked at me and said "supposed to be 112?, I got 118". I thought Oh chit, so we did it again and got the same reading. Glenn said that this is not unusual but this was a little "out there". So we advanced the crank gear and ended up with 113, did this twice to make sure.
I called Erson cams this morning and talked to one of their old time techs, he was very familiar with the MTS grind and said many variables come into play including the machinist who grinds the cam, the cam and crank gears, the timing set ( I used a Cloyes true roller and it was tight) etc. He said its always advisable to degree the cam....as I re-confirmed that to myself by example. So if you can ....by all means do it!
Anywho here's a few pics with the intake and carb just sitti'n there, need some dyno headers badly to get this thing on the pump. Might try modifying some BBC's, they are pretty close.....and yes, Glenn and his dad are great guys
