The intake you are currently using benefits higher RPM applications, 2500-6000. If you are not changing your gear ratio I wouldn't go with too large a cam as you will not get the benefit on the road. Reason for edit: No reason given.ĭepending on how you plan to drive your *street car* will affect your choice of cam. Retired, but working part-time on 50s-70s cars & trucks.Įdited by MikeB on 11-24-09 08:01 PM. Now has 355 with Vortec heads, RamJet roller cam, LS6 beehive springs, TH350 490' when installed at the proper 1.700' height.ġ982 C10 SWB pickup: Unmolested base truck, original paint.

510' lift springs should really be rated at. But, be sure to check retainer-to-guide boss and piston-to-valve clearances. IMO, the best stock-diameter springs out there are CompCams #26981 Beehive springs. Some of the newer cams in that range have almost as much lift as an older design 280. If your CR is only 9.0:1, I suggest you stick with something like 262-270 advertised duration. Reason for edit: No reason given.Īny idea what your compression ratio is? Even the CompCams 280 Magnum cam mentioned above would probably like 10.0:1 to make decent cylinder pressure. IF YOU CAN, YOU NEED BETTER TIRES AND YOUR SUSPENSION NEEDS MORE WORK!!Įdited by grumpyvette on 11-21-09 12:47 PM. IF YOU CAN,T SMOKE THE TIRES AT WILL,FROM A 60 MPH ROLLING START YOUR ENGINE NEEDS MORE WORK!!'! Once you get to more than about 210 dur lift or tighter than about a 112 LSA, a low cpr 350 with a stock stall and a 2.56:1 rear gear, won,t start running correctly, as long term transportation without some matched mods like headers or a stiffer rear gear etc.īe smart, learn from others experience, not thru regretting you installed a cam thats a bit larger than ideal like most younger guys do.

If you really want to push the limits this cam below will work also, but its really best with a 3.36:1-3.73:1 rear gear, and it won,t have the same low rpm torque but it will have more peak hp.

Then a cam similar to this one I linked to,will be about correct, it will boost hp about 30 plus, pass emission testing and run correctly with that stock stall converter and 2.56:1 rear gear ratioĪND ITS ABOUT AS LARGE AS YOU CAN GO AND STILL HAVE NO (ZERO)PROBLEMS
