I always thought they were 70s smog head 305s
A 307 cu in version was produced from 1968 through 1973. Engine bore was 3.875 inches with a 3.25-inch (82.6 mm) stroke. All 307s had large 2.45 in (62.23 mm) journals - the crankshaft is sourced from the 327. Pistons used with the 307 share the same pin height as the 327 but retaining the 283s bore size (prior to 1968 it was possible to stroke a 283 into a 307 where aftermarket pistons had to be used). This engine was also used by Holden in Australia and by General Motors' South African arm.
Right. The 307 was the replacement for the 283. And it was used in the '68 full size cars too, but by '69 the standard V8 for those was the 2bbl 327.
The 283 was way better then the 307 imo
I've got no gripes with the 307, or any small block really. They all served their intended purpose well. I will say the 283 ran as smooth as a sewing machine though.
And they took a licken too.
Wish u were closer, i need that 12 bolt
If its GM's own axle and not an eaton isnt my g80 an eaton posi?
I learned how to drive in a 73 also. A 250 straight 6, manual brakes and manual steering. Good memories.
Replaced a 6cyl in an 81 Custom Deluxe C10. Built a bored(4.00”) 307 block, 327 Corvette rotator assembly, RV cam, and a cast iron intake w/2bbl Rochester. That engine was so durable(8yrs), responsive, and fun.
Everybody wanted to tell me it would run hot. Not. That truck went through a lot until I sold it in 91.
So my 79 k20 has a d44 front. You think its been swapped, or leftover from transition?
