New cam on the way!

It's an Isky Cam, 224/233, .578"/.597", 112 LSA.

Will be looking for a 3k stall. What do you guys think?

More stall FTW.

I've been told that a 3k stall will actually stall to about 3,500... that would be my target stall speed.

Get a 3200-3600 stall. you probably wont be happy with that low of one.

Edge sent me what I wanted to be a mid low 3k stall for a 650+ motor. I stressed the amount of ass the engine had and the porky weight fo the vehicle. ...4800... I though they we're really on top of what I was asking for, but I should have just told then I wanted a tight 2800-3000 and was making 900hp. That is what you have to do to get the right converter.

None of which is a big deal - thats just part of it. It's why you get free restalls because you'll never get it right the first time. Just take it from experiance. Buy the most efficent 3000-3200 stall you can get with a 2.2ish str. I bet money it will make 3400 and you'll be tickled to death with it.


Rule of thumb is keep the str resonable as to keep loss low and...

Ordered stall size = ((Actual desired stall - 2800) / 2) + 2800

3150 = ((3500 - 2800) / 2) + 2800

3650 = ((4500 - 2800) / 2) + 2800

So if I want 3,400rpm stall, I need a 3k stall. Sounds right to me.

It depends on what stall you get

My stall is a 3200 and it stalls maybe at 3300-3400 and flashes to 3500-3600.

Ive always heard if you have over so much HP it will flash higher. Whether this is true or not I don't know.

More TQ is what stalls one higher....so does more weight.

True dat. You MIGHT get 3200 out of it with the 5.3L. I would go 3200 so you can get to the stall speed you want.

Nice cam BTW. Those 5.3Ls LOVE duration. I assume you are getting PRCs and pushrods?

I'm running stock pushrods and 918's right now. Are pushrods something I should really think about? If so, I'll pick some up.
