L78 motor cam opinion's

I would second the thought about the Competition Cams blueprint grind for the original L78 chev cam
I asked the same questions a year ago (just rebuilt my stock bore L78 out of my 1968 L78 Nova in Jan 07)
Have about 500 miles on it now-it is just getting to the point where I am going to start running it hard(haven't went over 4200 rpms yet) great performer, idler, etc
My 2 cents

Ty, yes it is a great cam.. I really like it. I have had the motor done now for about 6 years and put roughly 6 thousand miles on her cruisin around town and it's been great!! One thing I would HIGHLY RECOMMEND to you is now that the motor is just about at/past it's break in point is to start running AMSOIL 20W50 full synthetic severe duty racing oil. I use it and I think it is awesome. I have noticed that my solid lifter valve train is less noisy using this oil. You can also leave it in the engine for a couple seasons if your not driving the car much.. It will not collect moisture either. I know there have been many discussions here on the board regarding motor oils and I'm sure some guys will disagree with me, but I think this stuff is "THE BOMB". It also offers excellent engine wear protection!! Just some "food for thought". Good luck with the new engine!!

I would advise *against* the Comp L78 blueprint cam...the Crane/GM unit is the one you want...trust me, all of us in Pure Stock have been there, done that...you need to sit down with all of your engine specs and figure out your true compression, and that will tell you where you centerline at.

If you,ve got new heads..it's good insurance to put NEW springs and keepers on now. Almost lost my engine last year when an exhaust spring broke. I was lucky it didn't drop down.

Joel...there was a large thread about modern engine oil and cam break in a while back...forgot what compound is missing but its needed to help break cam in.

I think it is Zinc

It is Zinc. I have a solid cam from Bullet in my L78 and they sugested I use Brad Penn oil in my motor because it has the Zinc still in it. Its a Green oil same as the old Kendall oils. Here is the link

Suppsedly the EOS is done being produced, stop by your local GM dealer and clean'em out

Rob & Marlin why is the Crane Cam better than the Competition L78 Grind?? Have you guys had negative experiences with Comp. Cams??
