Cam for torque question
What rear gear are you running?
running an 8.75 3.23 sure grip now. it was an AMC 20 with 2.87's and it was a dog...it's much better now with the 3.23 and 2200 stall.
If you have had a 318 with an xe268 hydraulic with stock rockers, I'm, sorry but you cant tell me your valve train is quiet.
I ran it once at Mission Raceway in BC Canada and it ran a 12.92 at 102mph.
In gear at idle it pulls about 9" of vacuum, out of gear about 15". I've got a vacuum can that is all in at 8" and limited to give me 24* advanced at out of gear idle on manifold vacuum. 18* initial with mechanical all in at 3200 and 40* total...the dyno showed that any less timing was a loss in torque and hp. more quench and I might be able to run a tiny bit more advance before detonation. I have no detonation issues at all with 92 E10.
It's a good strong motor but because of the duration and overlap, it stinks and the vacuum is low.
All I want to do is find a cam that will give me a little more acceleration (Torque) at a lower rpm, a more pleasant breathing experience while cruising and a little more vacuum so I can stop after smokin a cheby 350....which it does....smoke 350's.
I know the teen doesn't have the displacement to make a ton of torque short of a massive overbore or a stroker and by it's nature likes to run at high rpm's but I should be able to move the powerband down in rpm a bit...if by no other means than an adjustable timing gear set (which it has) and is as close to 106 as I could get it at 105.5 intake centerline.
