Would like your suggestions. I have: -Gen 1 SBC 355 10:1 compression -Single plain with dual Quick Fuel 650's -Dart Iron Eagle heads with 215cc intake runners. 64cc chambers, 2.02/1.85 valves TH400 with 3200 stall 3.73 rear gear limited slip All in a 1951 Chevy Styleline Coupe, g***er "tribute/ wanna be" Mostly street/show with limited strip time Looking for roller cam & hydraulic roller lifters that will give the good lopy sound, snappy response, and performance to compliment "g***er" look & setup. I just wiped out a lobe & hydraulic lifter from Comp Cam about 5 mins. into 20 minute break in. Bottom of lifter was dished .094"! Followed break in to a T. Also what companies cams are you all running? Thanks
Comp cams are just as good as anybody else's, and I doubt that the brand of the cam had anything to do with the failure. Something else could have happened. What were your prelube procedures and what type of oil was in engine for the break in and what was your break in procedure? If you've got that much metal floating around in that engine, it's gonna need a complete tear down and clean up. My past experience with cams from any grinder is to tell them what your engine has in it and what you are going to do with it, gear ratio, etc.Use a good break in oil, and then run one of the oils with a high ZDP content. I've had good luck with Amsoil "Premium Protection" and Amsoil "Z Rod". Full disclosure: I am an independent Amsoil Dealer. I'm having good success with a Comp Cam XE268 solid flat tappet setup, but I'll admit the "pucker factor" on initial start up and break in on an engine with a hi lift cam, flat tappets, and stiff springs is very high
