Chevy small block perhaps?

[mjferencak]

Anyone hear of anyone putting a carbureted chevy small block in the H3? I have a 350 that I may keep a 350 or stroke to a 383. The reason I'm asking is because I cranked my truck today after work and had a huge plume of smoke come out the exhaust. So my piston rings and/or valve stem seals are going. Engine has 237000 miles and I've been noticing a loss of power lately. Wanted to do the 4BT conversion but I love the thought of a carb'd small block in the H3. Any thoughts or should I just go with the 5.3 that comes with the Alphas?

LS3 is the answer lol

it'd be possible to do the SBC swap, but for the same dollars you could to a 5.3 and have something that would be far more sellable. Something else to consider - the front differential has trouble at stock 5.3 power (even with the cast-iron case), so adding more torque of a 383 would simply make you poorer because you'd need to buy a front differential or 10 to keep it on the road.

something else to consider - I see you're protecting us in the Army.... while right now you're where smog rules are lax, that may not always be the case and such a move would pretty much guarantee that you'd be selling your H3 before you moved.

Thanks guys for the feedback. I do appreciate it. After sleeping on it last night and giving it some thought. I'm just going to bump up to the 3.7 remanded.

3.7. Booooo. No creativity with that.

I know but I can't have the H3 down too long doing a 4BT. I wish there was a conversion kit off the shelf for the H3 4BT. It would make it quick and easy if there were one.
