cam degreeing

ok first of all, i KNOT that my English suck ball but try to get over it THANX.

i got a huge 1979 pontiac parisienne 2 door with a v8 305. this spring the engine will got a minor overhaul. for you guys here it's minor but for me it's a lot. fuel pump, oil pump, water pump,manifold, carb, camshaft + lifter, valve spring, radiator and stuff like the rubber tubbing, trans and fuel line etc.

so since i get a new camshaft i already learn how to degree it but how much degree and does i retard it or advance it?

to give me good advice you need to knot my cars a bit. when i drag race with it he take off like a bomb but thing get ugly after that. i got lot of toque at low rpm but when the speed get higher with is weight pfff.

i install a shift kit on the transmission AFTER the drag season was finish so i never drag race with my shift kit. so what i do. advance ? to try to get advantage of my shift kit? or i retard it ? to take off like the the road runner ? ???

ps: do retarding the cam change the sound of the engine like advancing it?

degreeing cam

Are you referring to the degree slots on the lower timing chain pulley? If so one slot gives you more bottom end, the center slot gives you midrange performance, and the other gives you more top end performance. Most everyone uses the middle slot. Usually indicated by a small circle stamped on it.

If you are referring to degreeing your cam with a degree wheel. It would probably be a waste of time on an engine such as yours. The cam manufacturers are pretty good at making cams line up properly. If you do want to degree it. The only real method of knowing if it helped any is a dyno test.

i was asking for the degree wheel, but it seem it not needed on my car.

but the degree slot give me the same dilema.

the shift kit let the engine run longer at high rpm before switching gear. i think that to set the slot on high rpm may give a great combination. that seem logic to me.
