I have a bagged 2003 Chevy Silverado it’s got a 5.3 214/222 .550/.550 lift 108 LSA chopacabra cam by Texas Speed. Long tube headers 1 3/4s, new valves springs.Is a 3000-3200 stall (4L60e) from Circle D a good combination with my current build? Appreciate your time

 

I think that stall sounds a bit high. I'd call Circle D and talk with them over the phone to get the best combo for you.

 

Too high in what regard? Not trynna argue just genuinely curious. I’m planning on getting 4:10 gears and TBSS intake manifold in near future

 

It's not that big of a camshaft so the stall rpm doesn't need to be very high. I would have said a 2,600-2,800rpm stall would be better.

 

I see, I’ve seen some guys run 3200 stalls with truck Norris cams and those have pretty similar specs with the chopacabra I know the TSP chopacabra is a low lift cam but they’re pretty similar

 

lift doesn't really matter when choosing a stall converter

 

What would you recommend?

 

I’m planning on running 4:10 gears, TBSS intake manifold, bigger injectors, good tranny cooler to support stall in the near future

 

How does it idle with the stock stall?

 

Because your engine will still make good power from even below 2500 probably, and you are just wasting it with too high of a stall speed converter. If you want a higher stall speed converter, you should get a higher RPM cam. Get it? Low RPM cam, low stall speed converter. High RPM cam, high stall speed converter.

And you have already been given the best possible advice, get the converter that Circle D suggests
