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.
