Ah very nice. One last quick question would a 2800 stall still be good for towing?

Re: 5.3 to 383 stroker

The looser the convertor, the more slip it will allow before stalling (i.e stall convertor). Unfortunately that means more heat.

If towing is a real concern, then it changes the way I look at the setup just a bit, because your at a slight disadvantage in displacement. I'd be staying with a lower stall (more like the 18-2300 range you were considering), and a cam that makes as much tq as fast as possible, more like what many of the 4x4 and RV owners choose. Too much cam and stall with a trailer means you'll end up spending a lot of time slipping and out of the power band (inefficient power), wasting a ton of energy (fuel, heat).

If you really want to tow bigger stuff like v8 boats, skidsteers etc, then starting with a 6L becomes WAY more practical. The same amount of work (cam upgrade, stall, headers) in a 6.0 lets you run way more cam and still make gobs of torque. I literally have pulled stumps out with my truck on drag radials (I really wish I filmed that).

I officially have overused the (parenthesis) in this post.

Re: 5.3 to 383 stroker

Ok that sounds good, I figured as much (that is why I considered a 2K stall first) ok I will make sure the cam I choose makes torque fast (fast for a 5.3) Sometimes I wish I would have gone with a little bit heavier truck and just got the 6.0 would have been a little bit better than my 5.3. I just thought I would add in the parentheses of my own haha. Thanks again

Re: 5.3 to 383 stroker

Its all a give and take. I wouldn't be afraid to tow something with my high stall, if it was only once a year for a few miles.

short duration cams will probably be your best bet. A higher lsa won't chug quite as much in traffic, 115/116 probably adequate. It'll also help minimize surging which becomes very sketchy with a loaded trailer or in traffic.
