F-BIRD'88 Do a compression test before taking it apart.

stallion0606 I used to race it in the mudd, but that is over. now its just for offroading purposes only or weekend beast. Rockcrawling and what ever I can find to climb. I havnt taken it apart yet and looked inside or did any measurements, sooo I am probably going to check it out and see.

F-BIRD'88 What do you do with your 4x4. Low rpm low speed rock crawling or.
high rev mudding, mud racer?

F-BIRD'88 283's are a great base for a supercharged motor using a Weiand 142 blower.
A low compression ratio is desired.
Any of the modern heads can be used on a 283 including L-31 vortecs.
305HO heads are popular. and work great when ported w1.94x 1.60 valves.
The 58cc L-98 ZZ4 350HO aluminum head is great on 283's too.
Does the 283 have flat top or domed pistons?

A low compression blown 283 with reworked ported modern heads will work great in a 4x4. big power in a small package.

high perf 283's like to rev up and like aggressive rear gearing. Especially in a 4x4 with tall tires.

what heads do you got laying around? casting number..
Does the street supercharged 283 interest you?
not hard to do. Big results.

There are lots of ways to build up a powerfull 283. Getting the heads and compression ratio right is critical.
Most of the 283's were low perf low compression engines with lame small port small valve heads.
But thats easy to fix. lots of good ways to skin this cat with very impressive results.
Does the 283 have flat top or domed pistons? standard bore or... What matters is if the basic 283 short block is in good condition or needs rebuilding. Do a compression test.
Don't be so ready to ditch this motor.

lg1969 Take that 283 put it in a vega. You will get the power and MPG. Or better yet, Build a Rat Rod

vinniekq2 I have 2x 283s I picked up for $50.I think I will look for an old chevy2 or like the other poster said (blyndgesser) some light weight car.My plan is to make about 360 HP.The 283 has very little torque so she will get some gears.I wouldnt go so far as to say I will use an RV cam far its just a whim,,,looking for heads that will flow enough air and fit

In my opinion, no. It just doesn't make the amount of torque that is needed. You'd find yourself running it floored much of the time unless you were driving on pavement.

Personally, I'd consider anything smaller than a 350 SBC incompatible w/a 4WD full sized vehicle (Chevy Blazer/C-10 truck, etc.). A 305 might squeak by, but that's the absolute bottom line. Now, if you had an import/LUV/Ranger/S10 all stripped down (meaning light weight) you might do OK w/a 283. But any place a 283 fits, a 350 fits....

1971BB427 As mentioned, if the heads haven't been rebuilt to run unleaded fuel, then they need all SS valves, and hardened seats. My local guy charges $300 to redo them, and at the same time he'll make the intakes 1.94" for a 283, or 2.02" for larger SBC with 4" bore.
I just got a pair of old 2,02 camel hump heads from him, and I just welded up a bracket to make my alternator mount on the front two header bolts, and adjusting arm off the water pump.

swvalcon 305 heads make a good update for a 283. A lot cheaper than setting up 283 heads for unleaded gas and they have all the holes.

stallion0606 i mostly deal with off road vehicles, but i do have an 85 trans am. now apparently the heads are not drilled or threaded might be a problem. now what can i do to it for a 4x4.
