Does anyone on the site have a 283 motor (Stock)
in their 67-72 pick-up? I have a block freshly bored .30 over from 1958 and wondering if it will have enough torque and horspower to power this pick-up without having to go hi-performance.Currently it came with a 292 with a four speed muncie with the low first gear. |

Re: 283 small block into '67' pick-up
Boring it will help the horsepower, but torque will be minimal because of the short stroke. Its a top end racer. I think if you change the crank to a 350 this will help....Im not sure.

Re: 283 small block into '67' pick-up
I have an old tired 283 in my '67 stepside and it runs great and has enough power to get into trouble. Not sure what you are looking for but it is fun to drive.

Re: 283 small block into '67' pick-up
I had a little experience with the 283, One snappy little 8 I think you'll be happy depending on what your after. Not a torque monster though.

Re: 283 small block into '67' pick-up
If you add a 327 crank, you'll get a 307...

Re: 283 small block into '67' pick-up
The 283 is a great little motor for these trucks.V8 power w/6cyl economy.

Re: 283 small block into '67' pick-up
283 is a real nice snappy motor. You can have some fun with it. If you are looking for a race motor go with something bigger (350 or 400). But we have done a couple of 283's in the past that have plenty of snot. Nothing fancy, GM 327 high performance cam & lifters, LT1 high rise dual plane intake, and a nice set of 1.94 valve heads (if I remember right the 2.02's will not clear the cylinder walls). Good luck

Re: 283 small block into '67' pick-up
Mine has a 67 283 power pack motor with the 327/350 cam. Has a really lumpy idle, sounds killer. Doesn't take off real strong (350th trans and 3.07 rear) but does pretty well. Also, I'm used to my LT1 Impala and a 345hp Cadillac, so I guess it just doesn't take off like they do. I am very happy with the truck, but I also did not build it to race.

Re: 283 small block into '67' pick-up
Currently I have a freshly rebuilt 283 (in front of a th350/NP208) in my '69 K10 Longbox. It's a very dependable motor, nothing special but it gets me down the road. It won't chirp the tires or anything but that could be just the extra weight I'm pushing around.
If I could do it all over, I wish I would have experimented by using some of the things a few have said here when I rebuilt the 283 two years ago.

Re: 283 small block into '67' pick-up
I have a 68 C20 that I just purchased and it has a 283 w/ 350 heads and it seems fine. The previous owner said the 350 heads "breathe better". It has a RV cam and a TH350 trans. 410 gears in the rear. It was a 6cyl. w/4-speed and 456 gears, but the previous owner converted it. I just scored a 4-speed and everything to switch it back to a stick out of a 70.
Are you going to stay with the manual transmission? |

Re: 283 small block into '67' pick-up
Here's a good linky for info...It is geared to 307's, but I think alot will also transfer to 283's. After all, a 307 is simply a 283 with a 327 crank (a "stroker" 283)

Just wondering how your fuel mileage is with the 283 on the highway? How is your R.P.M. @ 60 miles an hour? Are you burning any oil and how is your top end power on the highway. I am not looking for a race unit, more reliability of the famed 283. Mine is bored @ .30 over is a 1958 vintage block, I believe I mentioned, just want to make sure I'm not wasting my time. |

Re: 283 small block into '67' pick-up
My dad has a solid lifter, bored 30 over, '65 Super Sport Chevelle style cam and old style LT1 Valvespring 283 in his '67 shortbed with a Saginaw 4-speed and the truck runs great. When he had the stock 283 with the 3 on the tree, it still ran good and would get down the road. You shouldn't have a problem with it at all.

Re: 283 small block into '67' pick-up
My 4x4 has a bone stock 283 2bbl. with a granny 4 spd. It has enough power to pull anything. With 3.73 posi gears, it revs a bit on the highway. I try to keep it under 60mph. I haven't hooked my tach up yet, but I didn't get it for over the road driving so haven't worried much about that yet.
I get better than 10 mpg. How much better I don't know. There's been too much snow to unlock the front hubs much since I rebuilt the carb. It starts on the first or second crank every morning. Even at 14 below. I wouldn't trade it for much of anything. I've never had a stronger running lower maintenance engine.

Yes I am going to stick with the four speed SM420muncie stick shift, had too many problems with automatics plus i love the feeling of pushing the clutch and shifting. Better power ratio control and much more dependable. How is your fuel mileage with that set-up? Are you getting good highway acceleration?(top end) |

This tells me the story of the little steam shuvle that could, lots of guys tell me to go high performance but, I know a lot of high performance big blocks in the shop to be rebuild after blowing them. The 283 apparantly has bigger cooling jackets and thicker cylinder walls, hence better heat displacement and less wear. |
