The 350 was the 175hp version. It ate the camshaft ( flippin’ GM cost cutting....inadequate hardening of the lobes) within 15,000 of her purchase. After this, I deduced that smaller, short stroke engines weren’t up to towing. When I get around to building the LS based engine for my ‘03 Silverado, it will be based on a 4” stroke crank. I think a 382 ought to work nicely.

Yep, that will make a very nice tow engine with a broad power band, and they have excellent cylinder heads. I fooled with the larger bore 6.0's for quite a while. A 4" crank 402/408 combo makes fantastic power for it's size.
