So, with my 340 set up of Air Gap Intake with Fitech Fuel Injection,.030 Flat top pistons,727 with B&M holeshot; good or bad?
The Holeshot I have says 2400 stall. That not enough for this cam?I would buy a better torque converter if you can afford it. We used a protorque on my buddy’s car and it has been pretty impressive, high flash stall speed and not loose when you are driving normal.
I think 2,400 RPM is a good starting point for a flash stall with this cam. My experience with B&M and their rated stall speed wasn’t very good but their quality may have improved over the last 20 years since I ran mine. Lots of factors come into play like motor torque, vehicle weight, rear gear ratio, etc so everyone’s results will vary. My holeshot seemed to stall around 1,800 RPM or so. But if you got it may as well run it and see how it does.The Holeshot I have says 2400 stall. That not enough for this cam?
I was trying to look for why you disagreed with me and maybe it's a misprint on his part but a to 268/272 @50 ?I ran it in a 360, idled quite smoothly, not much notice at all. I really liked that cam.
Ran 13.30's with 3.23's and a 28" tire in a 3200 lb car without driver.
that's advertised, not @ 50I was trying to look for why you disagreed with me and maybe it's a misprint on his part but a to 268/272 @50 ?
Well that should explain a lot!that's advertised, not @ 50
mattax I was talking about the ubiquitous 214-224 type cams available from most all big vendors like Speed pro, Elgin, Edelbrock,
and what moparofficial said
if I was doing a rebuild and had to buy a new cam I would never buy a stock 440 or 440 Magnum cam-I can do better more low end and more top end
but I would not change a good running stock or magnum cam just to change cams well not exactly true
Back in the Day City of San Jose was burning up 440 propane bus motors 10,000 miles and they were burnt up Big warranty problem for Ma Mopar
stock cam had too much overlap for their rev range and load
shorter cam with about the same lift but fatter area under the curve really helped
but it took a piston change to really fix (design similar to KB step quench)even raised the compression
together EGT dropped 800 degrees- no more glowing cherry red exhaust manifolds
valves cool when they are on the seat and torch with long slow ramps
