Good morning guys. Its time to pick a cam. Need all your experience and help to get the right one. Here is my combination..
69' 340 engine,stock bore & stroke ( compression test - average 190psi )
X heads w/2.02 and 1.60 valves, Hooker headers w/2 1/2" exhaust
OEM Thermoquad intake w/demonsizzler built 800cfm superquad (stock jets)
Chrome box electronic ignition, demonsizzler recurved distributor
Manual A833 4 speed, 8 3/4 diff w/3.55's, 24"tire
This car is a daily driver with maybe an occasional trip to the track
I want the most possible bottom end and midrange torque without hurting top end too much, engine will not see over 6500rpm
I can go with roller cam, variable rate lifers such as Rhoads, or adjustable rockers if any benefit
(Possible future mods may include cyl head work,ie a good valve job, porting
etc.,x-pipe,3.91's, but not sure when these mods will be done)
I don't want to bother the cyl heads this winter
I think I should be going with short duration cam, but I need help with the lift, lobe separation angle and ramp speed,and whether the cam should be advanced or retarded. I don't mind lumpy idle, no power brakes.
Help me make her a tire burner... and thanks,Keith.
