Not Ranked
Camshaft
From what I read he wanted the best camshaft in the 2000 to 5000 range and that would be a hydraulic roller. I do not believe he is going to race the thing. He said it was a clone but he did not say he was going to race it. From the rpms he wants I would assume he is going to drive on the street and do some car shows with it.
The hydraulic roller cam and lifters run about 500.00 more than the flat tappet and will use the same pushrods and springs. The reason I use them is it takes about 3 hours of dyno time to break the camshaft in, check everything to make sure the camshaft is ok, then change the springs and run some more and then check the camshaft to make sure it is ok. If something does go wrong you are out way more than 500.00 and I do not have that kind of time to waste.
They used a bunch of technology 40 years ago that is out of date now. this is why a lot of the FE engines do not make any more power than they did 40 years ago. Build them the same and get the same results. I kind of like the new stuff that works better but that is just me. Good luck, Keith
