Question Cam timing

Read somewhere that advancing the timing on the cam ( with a buhsing)would help the low end torque. I have an Edelbrock "Torquer" advanced 4 degrees, and it don't feel any stronger. Anybody else have any experience advancing/retarding cams?? <img src="graemlins/pain.gif" border="0" alt="[pain]" />

Those cams are already ground 4 advanced so you have it set at 8 advanced which ism too much and probably isnt doing anything to further help the low speed torque situation

thats why you have to use a degree wheel to see if the cam is right on or not. in my case i ended up advancing it only 2 degrees. i havn't fired it yet so don't ask how it runs.

yep you have degree the cam in with a wheel, adjustments are best done with the offset bush as opposed to using one of the three slots in the lower pulley, as for performance a dyno is the answer but obviously that labour intensive! thats why the big buck motors use external belt driven assy's that are adjustable. good luck

Thanks for the input, guys. I may be opening a can of worms, or a thread longer than "No Topic", but what cam should I use, or what specs should I look for in a cam to be used in a 305, stock bore, 1.84 - 1.5 valves in a 70cc head, spreadbore manifold, Thermoquad carb, headers. I want to use it in my 1500 lb. T-Bucket. It will be used primarily for street. I want it to have good low end through about 5 grand, and sound really killer loping around the Taco Bell!!
This engine has roller lifters now, any advantage in going to roller rockers since it's gonna be a lower rpm motor??

I wouldn't use 70cc heads on a 305 or your compression will be too low. Are these the stock heads? If so, I'm guessing they're 58 cc.

You could be right. I am at work and the info where I cc'd them is at home in the shop. Yes they are the stock heads. Just wanna "perk her up" a little bit and sound "boss" cruisin the hangouts. (Don't guess I'll ever outgrow that)
