I am in need of a camshaft for a 1976 250 that I'm trying to bring back to life.
I'm on a very tight budget so most of my plans for performance have to be put on hold for now. The engine is getting bored .030 or .040 over. I am going to use a 1981 200 head and 255 flat top pistons, shooting for 9:1-9.5:1 C/R. Going to use a stock 1V Carter YFA carb for now, will eventually do a 2V conversion... I am going to use the 1969 timing set for better performance over the later gears. I am also going to run a dual out header...
I found a Comp cam for around $80. It definitely wasn't my first choice of camshaft but the price is right for my budget and it is about $10 cheaper than I have found a stock cam for.
It is part number 65-235-4 from Comp Cams, grind number F65 252H-10.
The advertised duration is 252 int./252 exh, lift is 0.425 int./0.425 exh, lobe separation is 110*, RPM range is 500-4500.
Duration at .050" is 206 int./206 exh.

Will this cam offer a bit more performance than a stock cam? Will it be suited to my engine specs or should I just buy a stock cam for now?
Edit: I might add that I am still running the stock rear gears at 2.73:1
