I do not want to have to put a ton of rpm into it while in gear to move at all. Hell it would be nice to idle up the trailer...........

Higher stall seems to me would have ot rev even higher to move.... I think the problem is I dont need a stall on here at all. This is not a race or drag vehicle... strickly show.

A stall converter just slipps till it's lock up rpm's. It will still move. With a bigger cam than stock, you power range changes from idle to 5500 to like 2000rpm's to 7000rpm's this is why you need a stall converter.

I guess im still lost the motor runs great! It idles on its own revs very quick and responsive, but put it in gear and dead she goes. Your suggestting a higher idle would fix this?

The go fast stuff will get used, but I goto events all over the nation, im not about to drive that thing 20-30hrs one way. Its gotta do some trailer riding.

What is your timing set at?

It should be somewhere between 5 - 10 deg before top dead center, at idle with the vaccum advance disconnected and pluged.

I have 383 stroker, 11:1 compression, .060 over, Keith Black pistson, 400 heads, 290 cam with 478 lift, TH350 tranny with a 2500 stall.

Ok here is the issue, just got the motor running very good, idles great and all now.... as soon as I put it in gear though it basically dies unless im on it. I assume this is due to the stall? Can I run without a stall converter and just run a normal torque converter? Would this solve the issue? I dont mind the performance lose as its just basically a show truck.

Any help of input would be great.

Are you running pump gas? 10.5-1 compression is about the max you can run with 93 octaine

What RPM is it running in gear??? Try turning the idle up and see if it runs. Should be able to run about 800-900 RPM in gear with the cam. Have you checked the timing??? Checked for vacuum leaks???

Timing is good, that was set when it was built/dyno'ed. The carb has no vacuum lines at all, its all mechanical, its a show truck, dont want all that running around in the motor compartment.

I have no clue what the idle rpm is cause my dakota digital gauges are not hooked up yet.... plus its one of those that you ahve to have it actually moving to calibrate it for speed/rpm. SO anyway I cant check that. So your saying if I idle it up a bit it should drive fine?

Its running supreme right now thats all I have access to at this time. yes it will be running some race fuel at some point but it would be nice to be able to load and unload this thing under its own power haha.

Anyone?

You need to get a timing light and a tach to see what the motor is at now. Just because it ran good on the dyno doesn't mean it is set correctly. Without a tach and a timing light you're just guessing.

I'm with Dave. You have to get your stuff hooked up or your just guessing. See if you can borrow what you need.

The timming was good when the carb guys tuned it. I didn't attempt to drive it while they where here though... Im not sure what the timming is at.

If it was running good when they tuned it and now when you put a load on the engine it does not run good means that the carb and timing need to be re-set.
