I came across this website outlining GM's 305 V6. It was used in school buses and some trucks.

Could this be the ancestor of our 60*v6?

I like the 478M - 254HP / 442 lbs. ft. of torque! And with a C/R of 7.5:1, you can boost the **** out of it! Now the question is, will it bolt up?

Redline 3200 rpm (on the 478) and dry weight of 925 lbs. Knock yourself out.

I think I remember seeing one of these things. Maybe in a 63 GMC pickup?
It was freaking huge! Almost as big as a SBC.

I had one in my 61 GMC PU, My father rebuilt it over the summer of 74. It was a Massive engine, as big as a big block, I went through 5, 3 speed trannys, most of them had destroyed cases. It had the shifter on the colomb. I mounted a mister gasket floor shifter. Reverse was across from first and when burning the tires it would fall into reverse and push the idler gear out the side. then We put a granny gear 4 speed and I took out 2 rear ends, my friends said I got the wheels 3 feet off the ground. Yeah it was a big strong engine.

I especially like the part where they stick two of them together to make a "double six" v12

It seems to me that with 7.5 compression ratio you could shave the heads and boost it up to about 9 and gain some significant hp and torque without boost. Can you imagine the throttle at a streetlight?
