GTA50

I'm in a bit of a quandry as I start putting my engine together. It's a 2.8 stroker (so 3.1 pistons and crank). I'm putting in a CompCam 260 grind cam, 1.52 roller tip rockers and a Cloyes double roller timing chain.

So, according to the instructions for the timing set and the cam, I have the option of degreeing the crank and cam or neither. If I advance the crank, I supposedly get more high end hp, if I retard, more low end torque. I know I'll have to check block clearances, etc. Degreeing the cam makes sense to check for and correct any irregularies.

My question is, is it worth it or should I just go with the stock settings - keeping in mind that this is my daily driver and I don't want to hurt the mileage too much.

Thanks

Gary.

just install it stright up. no sence in going to hi rpm power cause well the intake is a long runner.small plenum design and just isnt well suited to high rpms.

and to gho the other way with it would work but for more low end power u should have went with the 252 cam which is more of an rv/towing cam

The 260 cam will work fine, it's what I used in my hybrid a few years ago and was happy with it.

If you're not into trying it all 3 ways, I would just install it straight up, this will work well.

FYI, you don't "degree a crank", you "degree a cam". The cam timing and more specifically valve timing events in relation to piston travel is what is being measured when degreeing a cam.

Thanks for the input and the correction. When I installed the timing set, the instructions talked about degreeing the crank as it had three postions on the crank sprocket.

I did in fact install it straight up as I gather the 260 cam already is advanced 4 degrees.
