Interesting info about cams/valvetrain... Esp for the DIY guys...Hevy D said:Hey Mofo
The reason I went with Comp is because as there lobe profiles get bigger the lift stays the same at .550. This made sense to me cause the valve train is just about maxed at that lift and its hard enough to find springs that will work comfortably with that as it is. Its a sad situation, we can only get springs that have 80 lbs of seat pressure, and the lifters start to pump down at anything over 80 lbs of seat pressure but that aint enough seat pressure for anything over about 18 lbs of boost...if that.
Also I chose my own grind, it wasn't very scientific either, all I did was look at what Crower sells for a stage III supercharger cam and duplicated it in a Comp again because Comp keeps the lift within reason and also because they have very quick ramps. This cam is 274/274 advertised but at .050 its 238/238.
Anyway I think I have a fix for the valve train situation but I need to get my truck running to find out if I've learned anything or not.
As for FFW.....I would give anything to make it down there but at this point it aint lookin good. Still a month and a half away so we'll see. Dale
