Roller cam and FE engine

[82ACAUTOCRAFT]

I understand that the systems with the lifters tied by a bar, unlike the factory rollers where the lifters travel in a bore with a groove are proned to failure. When that happens, the lifter rotates and destroys the cam, the bits fall in the engine and clog the oil strainer and you have catastrophic and expensive engine failure! So I am told the small increase in power is not worth the expense.

82acautocraft There are link bars to keep the lifters from twisting. KC sells custom cams that make alot more than 10-15 HP over stock catolog ones. It's like anything else, you need to match the parts to get the best power and drivability from your motor. You need to remember that a cobra is light and only will take 600hp and 600 lbs of tork and still be streetable. Solids are nice for sound and do make a little more power at 6,000 rpm that hydro lifters, but who want to check the adjustment once a month for the correct lash,(I think that is with a hot motor). Build a lite weight valve train and you can spin the motor to 7 Grand. Crane make a small roller cam that is very streetable and makes strong power in the mid range. You didn't say what size the motor is, compression, fuel system, carb,FI, power adder, trans, gear ratio, what are you going to do with the car, 1/4 mile,show and shine, autocross, road race, you have left a large unanswered script to be filled in. I would also check with other machinists and FE builders about this. Check out the FE forumn. Gessford machine, Barry R. Dave Shoe, Keith Craft and Jay Brown would be good placed to start and get good info. Rick Lake
