Converter stall check

[Marv D]

The more power (torque) you make the more stall your going to see out of the convertor. Before you fight any further with the convertor (not saying you don't need something there) just you might get the tuneup a little tighter, try a more responsive carb, and get the timing dialed in. Advance bolsters torque in the lower rpm range. Trick is to get fuel and ignition advance to cooperate so you can step things up a little.

I made the assumption this is a 350,, when I looked back I didn't see the engine size. If so,,, You should be at 9.4:1 compression with a normal build, 64cc chambers, 6cc valve pockets, normal dect etc. With that cam you should be able to run 91 octane, have at least 10° if not 12-13° initial advance and with a tight curve setup, hold total advance at around 36. I think that would help with low end torque, and push the converter a little harder, giving you a tad more stall and launch torque. Just a thought, but before you go nuts on other things,, I'd spend some $'s at a good tuneup shop. If there is a dyno tune shop around Bozeman,, it may be $'s WELL spent.

If I want to keep her, I will buy the flowers.

Marvd, yes it is a 350. I getting ready to pull the timing cover off and check all the mech. timing ( off a tooth??? ). The carb is the first on the list to get swapped out. Were are looking at June 1st ish for that.

Thanks for all the help guys, I'm sure I will be back on looking for some more info and advice.

thats a pretty high lift, low duration cam

i run close to those specs with a 2bbl and stock intake and exhaust manifolds.

have you done a stall test?

Drop in low, Mash gasm and note when stall is before wheels spin? will king of give you an idea wherethe stall is at, no matter what was advertized
