FU's 5.3 to L9H 6.2 thread

[iamdub]

I will be towing, yes. Not sure on weight yet, son is just getting to an age where we can do stuff like camping and/or boating.

I was referring to ZL1 torque converter. It stalls around 2200 and they're built tough.

Tease. I thought you meant the ZL1 engine, the LT4.

2200 is a safe stall speed.

I forgot about the ZL1 torque converter, that would retain all factory function. I did a Yank converter in my TBSS because "everyone" said it was a required mod for the heavy truck and that was the worst thing I ever did and I swore I'd never do it again. Gas mileage went to crap and drove like crap on the street unless it was WOT.

Gas mileage on the 6.2 is excellent .

Magnaflow cats and Y-Pipe is a thing of beauty and flows great. Was good for seven horsepower on my truck.

Swath what part number for the Magnaflow cats and Y pipe ?

Swath what part number for the Magnaflow cats and Y pipe ?

51578. There are other numbers for New York and California Emissions. I believe they are all physically the same with the addition of government approved numbers.
