Camshaft options??

[JJB77FJ40]

I bpicked up and am refurbishjng a 77 FJ40 starting with rebuilding the 2F engine(1st time I have ever done this) with header and a Holley carb(Don't know what model). I have been replacing bearings and pulled the camshaft finding it to be worn (some lobes as determined by my buddy).

What are my options? Which cam (std. or RV) and what are the pros and cons(gas mileage)? Must I replace the cam bearings(I.m doing all this work while the engine is in the vehicle)? What if I don't replace the bearings?

Thanks in advance for all your help.

I honestly don't know the options for the cam shaft, but if the bearings look worn at all you should replace them. It would be a shame to have issues on a newly rebuilt engine. I am sure it will not be fun with the engine in the truck though.

I did look into custom regrinds at a place near Atlanta. (Reed cams) I had one in a Celica years ago and it work great. I put almost 200,000 miles on the cam and it still performed great.

I talked to them briefly about the cruiser and they stated they would need to see the cam, and get specs on my engine to to the right profile built. The quoted me a very low price for the regrind, to my specs.

New cam = new bearings and new lifters

Search Mark Whatley cams...

FWIW, there is a lot of thought that the only way you will benefit from a more agressive bumpy stick is if you raise comp ratio (surface head), and increase airflow w/ header, exhaust etc.
