All too common LS swap vs unique old school small block

[L31MaxExpress]

Factory HP ratings say otherwise.

I could car less about the HP to be honest. 300-350 ft/lbs at most vs 480 tq. I'll take the torque.

I'll take the HP.

If its not already apparant, I'll take the torque and use a stock or near stock converter, an overdrive trans and tall gearing. Let the big block use its torque rather than spinning it. That big block loafing along at low rpm will last 2-3x as long.

600k seems like a stretch, but it doesn't matter to me.

Why not do a straight 6 in the Obs that would be neat they didn’t come with it and is very reliable plus you could do fuel injection/turbo anything is possible I’m considering doing it I find them all day rebuilt for cheap

They came with I6s, just not here. They were optioned with a TBI 250 I6, a MPFI 250 I6 as well as an I6 Turbo Diesel south of the USA.

Didn’t know that I knew the square body had inline 6 but not obs I’ll have to look it up mine had a 4.3 tbi v6. Thanks for the info

You won't find much info on them, at least I can't, and I service Mexico and SA when it comes to performance parts. There was a gentleman on here that joined with a white single cab that had a I6 TD.

I have driven a factory GMT800 Tahoe with a L31 5.7 and NV3500.

GMT 800 Tahoe? That looks like a GMT 400 to me. But you are right, the early GMT 800 trucks in the Mexican market still ran the L31...and manual is more common down there. The Mexican version of the Silverado is called Cheyenne.

The I6 from Brazil? I remember that white truck. IIRC he was from Argentina or somewhere down there...
