Except the "knockoff" was much more reliable than the original

Have a link to where they sued?

I have seen many variations of that, and believe that it is a copy as well of the chevy inline 6. I, nor any of my cruiser enthusiast pals have ever seen any factual account of a lawsuit, despite hearing claims once in awhile. Just curious about a missing piece of history.

Didnt the Toyota engine come out in the 50s ? It looks alot more like the "Stovebolt" Chebbys (216,235,292) which had 4 main bearings vs. the 7 main bearings used in the '62 & later 194,202 (Sold in the UK),215,230,250 and 292 cid engines.

I know they imported the fj25 in 58'

Gas Land Cruiser engines are manufactured by Toyota. The F and 2F engines were also used in Toyota Forlifts. The F engine is supposed to be based on the Chevy 225 I-6 "Cast Iron Wonder" and some of the bottom end of the engine is rumored to be interchangeable. The main differences between the F and the 2F are the 2F's larger bore, the F's 2 compression and 2 oil rings versus the 2F's 2 compression and single oil ring and the fact that the F had two oil paths--through the filter or through the engine compared to the 2F where all oil had to travel through the filter before the engine.

The 235 had 4 main bearings; did the Toyota use 7 ?

Drawing a blank at the moment.

The Toyotas I've worked on, all were four mains.

For the 6.2 crank question, all have been cast that I've seen. Not sure on the 6.5's.

I rebuilt the 6.2 in my K5 Blazer. It's a bored 6.2L short block, with 6.5TD heads, a 6.5TD injection pump, non-egr intake, and a much improved cooling system (6.5 water pump, twin t-stat crossover). It also has the Banks Sidewinder turbo and exhaust system on it.

The truck is an 83 K5 Blazer, D60 front, 700-r4, 14 bolt FF rear, 37" swampers, I had it on a scale and it weighs in at 6500 lbs with me in it.

My advice: Stay away from the 6.2. The blocks break, even at stock power levels. The cranks break at stock power levels. ALL the heads have cracks in them. They don't make much power without a turbo, and they blow the head gaskets when you put one on. Yeah, I get up to 20 MPG, but that's probably because I had to turn the fuel way down to keep the EGTs under control at WOT.

To put it in perspective: My 6.2 makes respectable power, for a 6.2. Not too long ago I was following my dad (stock 97 F250 powerstroke). We both stopped at the bottom of a long hill and then took off. I had the pedal floored and he still quickly pulled away from me and wasn't even trying. The kicker was that he was pulling a car on a trailer and I wasn't towing anything.

I'll run this 6.2 until it explodes, then I'll look into a 6BT swap.
