I don't know the specs on the chevy 307 but they replaced the 283 as the base small block in I think '68. I put one in a beater '67 chevelle. With 1.94 heads, an AFB 4 barrel, a 4 spd and 3.73 gears it ran pretty good but smoked like hell. :3gears:
The 262.A little smogger chevy V8 from 75`or 76`.An old girlfreinds brother had a Nova with one in it..gutless little bugger!! Had a bore like a quarter and a stroke a week long :laugh: Never intended for performance.Olds had a 260 which was designed in a similar style.Memories.. Later,Tony.
You could actually get a 396'' in the 60's and up into 70' I think. In 71' as I recall, it turned into a 402" and was even offered in pickups(a couple are here in the area). If you do the math, a 402" miraculously turns into a .030" over 396". Kinda makes you wonder if we hit a bad run of oversized pistons HAHA.
I plumb forgot about the 307. I had a hundred friends with early '70s Malibus that had 307s in them. Man I'm losin' it! The 366 was a de-stroked 396 for trucks. We had one at my job when I started there back in the mid-80s and it was old already by that time. Probably dated back to the early 70s.
don't know the specs on the chevy 307 but they replaced the 283 as the base small block in I think '68. you're right, different from olds. found a reference to it being a 283 with a 327 crank... 3.875 x 3.25
366 The 366 came out in 1966 as a truck engine, it ran pretty good for a truck engine. It was not a destroked engine but a small bore. I used to buy cores from the dealer to get the cranks for 396s and 427s. The 307s were left over 283 blocks with a 327 crank, everyone hated them at the time but they weren't really that bad. I used to see all kinds of arguments over Buick engines because people thought the torque number on the aircleaner was cubic inch. Jim N.
The 302 was the Z/28 motor. SCCA rules dictated a max of 302ci to run Trans Am back then. Man, that guy's lucky he didn't get in my face and try correcting me... being a jackass, I would have said, "Those are Chevy engines you douche-bag! This is a Buick! If you know so much about cars then why can't you even tell the difference between a Chevy and a Buick?" But that's what jackasses say as a retort. Usually.
at that point you could have just looked at him and said " its a hemi" lol. or better yet you could hit him with the always popular 3/4 race cam, or a 350 big block. ive ran a part store for the last 10 years, if only you guys could here some of the stuff people come up with.
