283? Good V8 Swap Candidate?

We are looking at a 283 for a friends Jeep, I know the big standard is 350 but any experience with 283 performance?

Re: 283? Good V8 Swap Candidate?

There basically the same engine, just different bore, and stroke may be slightly longer in 350 also. Not sure about that however. Reason not to go with 283 is 1 - age, the youngest one out there now is approaching 40 yrs old. Engine technology has evolved tremendously over the last 35 - 40 years. 2 - 350 is much more common, has way better torque curve and HP. Way better fuel systems, ignitions, Blocks are made of better alloys, heads have better flow characteristics, More parts available. The only real problem is the engine is outdated. It was a great engine in its day, but its day has come and gone.

Actually I should have been more specific...the engine has been rebuilt, new stuff, very clean looking, some guy has it in his commando with a TH400 and doesn't have money anymore....surprise, for cheap would it be OK or better to find a 350

Buy the Commando, keep the engine and tranny in it and keep looking for a 350 for the CJ. Commandos are way cool.

Re: 283? Good V8 Swap Candidate?

the 283 is a good quick reving motor, and there are many performance parts that will work on the small block. had a mild 283 in my cj7 with auto trany, it was more than enough to carry the jeep around. just swapped in a 350 and working the bugs out of the new motor. it is stronger but thats because of so many performance parts on the 350. the 283 was .060 over with 283 hp heads "power pack". planning on keeping the 283 and refreshing the bottom end and then possably going into a scout. the bore and stroke on the 283 is 3.875/3.000 stock. the 350 is 4.000/3.480 stock.

Make sure you check that it is not a early 283 with a front motor mount and no side mounts. Not that it wouldnt work you would just have to come up with some kind of front mount

Re: 283? Good V8 Swap Candidate?

About a dozen years ago, I built a 283 with early 80's 58cc 305 heads with 1.84" intake valves. The 283 was a very responsive engine, and had hard seats for unleaded gas. Another advantage with a 283 using 305 heads is the choice of brackets for an alternator, power steering pump, even a factory supertine belt could be used with the correct water pump. As for stump pulling, low RPM torque, the 283 is not the SBC champion for this type of performance.

[img]images/icons/tongue.gif[/img] The 283 was the 'engine of choice" for swapping into flatfender Jeeps and early CJs in the SIX-DEEs. At that point in history, not much was being done with axles and drivetrains, so the little 283 with only a 3" stroke was easier on the stock Jeep components, and had enough revving capability that you could actually drive the speed limit without changing axle gear ratios. If you left the engine stock, the Jeep would live. If you tried hopping it up, well.....there goes the rear....oops!....there goes the front ax.......oops!....there goes the tranny.[img]images/icons/crazy.gif[/img] The TRICK was to have the engine lug down and DIE before something broke; that way all you did was cuss and restart it, instead of having to FIX something. 283's don't have much low end power in stock form.[img]images/icons/tongue.gif[/img] One of my buddies was killed in his Shev-Lay 283 powered flattie when he blew out the front drive powering up a hill, and the Jeep got sideways on some loose stuff and rolled several times.[img]images/icons/frown.gif[/img] The 283 is a "little" engine, and it was a real performer for it's physical size which made it very popular among rodders. It is, however; as was so well pointed out; yesterday's technology.[img]images/icons/crazy.gif[/img]

"if some is good, more is better (?)"
it's the american way...... go 350 at least.
same package size.

that's like packin a li'l weenie 9mm, when you can carry a
.45 in the same package size.
