what should vacuum be - 350 chevy, 9.3 CR, 236 @ .050
Im trying to slowly get my engine tuned just right.
With a 350 chevy
236 duration @ .050 cam on 108LSA
base timing in the neighborhood of 20 degrees
what should me Vacuum be at idle.. at .. 1500rpm..?
trying to figure if I have a vacuum leak, and also if my vacuum isnt right, to adjust how rich /lean my carb should be..
please help, im new to the concept here
This motor loved the high base timing u suggested, but at 3rd or 4th gear, when id back of the gas, I was getting massive detonation. I have a 3,000 stall already.. is that not high enough and causing the detonation?
its a rochester Qjet
and yea I noticed it idles pretty ****ty with low timing. THe higher timing, it sounds much better. I only changed it back to low initial because of the detonation.
is 6" vacuum in gear enough for my power brakes? or do I need a pump..?
i have a 383 / 700r4 with the same cam spec. except 110°lsa.
i have 31" tires with 4:56 gears.
presently running a 12" 2500 stall, should i also have a 10" 3500 ?
oh, i have the 4150 holley 770 street avenger / 4.5 pv
my timming is as f-bird'88 suggested.
not to hi-jack this thread , i hope .
