Yeah I probably ended up with stock 350 power, but I enjoyed the build, how it wound out, and 13 mpg in a '71 K/20 with 4.57s,37/14.50 rubber, utility bed full of tools, materials in the bed, and ladders/scaffold on the racks. I always wanted to try that motor in a shortbed 2wd.

Re: Funny truck stuff from the board members

I rebuilt the 305 that was in my '85 Pontiac Parisienne wagon and stuffed it in my '68 Skylark. With the 700 trans, I got 18.5 MPG in rush hour traffic. That low first gear made it a great hole shot car, even with the 2.73 axle. I put in a little Edelbrock cam and added a 600 CFM carb and the smallest cam Edelbrock sells. It really could have used a 3.42 or so axle, though. I sold it and the guy who bought did that.

My father bought a new El Camino in 1968 that had the 307, it was a damn good motor. They were an under square motor, 283 block with a 327 crank which made them quite torquey for a 2 barreled carb engine.

1968 - 1971 with 2 Barrel Carb
Max Brake Horsepower: 200 @ 5800 rpm
Max Torque: 300 @ 4200 rpm
Stroke: 3.25
Bore: 3.875
Compression: 9.00
Firing Order: 18436572

For what it is worth a 307 is an over square engine, 3.875 bore x 3.25 stroke.
a 307 is basically a factory built 283 stroker.
My brothers and I had alot of fun "racing" a built 307 we put in a 62 Chevy II.

A much better engine than the tiny piston, tiny valve and 350 stroke = 305 smog motor

Yea for sure, Iíve had a few 305ís and never been a fan of a single one of them. Between cracked heads and no torque they arent my favorite. The only one Iíve ever been somewhat satisfied with was a buddyís vortec 305 in a 97 regular cab short bed, the vortec heads helped it for sure but not enough that Iíd want one.
I donít have any experience with the 307 but Iíve heard decent things about it. I like the 283ís a lot, revving little bastards they are, and the 327ís arenít much different. There love child canít be too bad... A de-stroked bigger bore engine like the 302 or 307 is a great combo for high rpms. A small bore longer stroke not so much, especially with weak heads.

I was designing a piece of equipment that would absorb the radio frequency energy from a transmitter, many years ago. I got all the parts lined up, and then flipped them around to check the model for clearances, and sent the drawing to manufacturing. All the parts came back, and it didn't go together, because I had flipped the model around. Luckily, I was able to use a few parts off the shelf to make my design work. About $1000, which is chump-change in the defense biz. Pretty embarrassing, anyway. Magic fingers can still miss the target.

You do that too?? Sorry to say this, but your shortcoming sure makes me feel better about myself

I had a 307 wear the fiber timing gear out. I had a new dbl roller for it looking for time to install when it jumped. Ended up with bent valves, 120k on the motor. That's the one I rebuilt. Minimal machining required. The crank was micro-polish ready, no cylinder ridge, and they only needed a light hone for hatch marks. Everyone was impressed with how little wear that engine showed.

LOL. Just a thought, someone spent many hours looking for a part off a frame-off and searched everywhere, came up empty. Turns out it was right next to this computer

Can't tell you how many times I've looked for a part, and the last place looked was literally the last place possible.

From another board just now..
