xj to 283 chevy motor swap

[texasxj]

I have a 84 xj with a 4 banger. I have a v8 283 chevy sitting in the garage with screwed up pushrods. Does anyone know anything about replacing them or what is causing the motor to bend them???? Also I need some motor mounts-anyone know who makes xj to chevy v8 mounts-besides frickin rip you off advance adapters.

Thanks clayton

If that engine has bent pushrods there is probably something major wrong. 99 percent of the time pushrods get bent when a piston slaps a valve,which could be anything from a broken timing chain to broken valve stems. That engine would probably have to be completely rebuilt to be safe

If you're going to put a smallblock in there, why not go balls to the wall and get a 350 or 383? I know you already have that other engine, but since it sounds like its damaged beyond basic repair, junk the damn thing and buy a running 350 from a junkyard for like $500 tops. Same physical weight and size and buku's more power :gigem:

id say dont bother with the 283 and get a 5.7l vortec from a chevy truck to put in there. more power and fuel injection all in one plug and play package. i went to the junkyard today here in town and they had three or four of them. if they'd had them when i was in the market for an engine, that's what id have in the scout. try to find s low mile for around $1000, you'll have that much in the 283 by the time you rebuild it.

you're all wrong, just go the the yard and pull a mildly used I6 for super cheap and be done with it. its got all the power youll need to throw around the 84 unless you're planning on racing it

[uglyota]

does a 4banger mean he has weaker tranny/tcase/axles too?

[JeepPhisherman]

should be the same 30/35c
tranny is almost deffinitely some pos
dont know about the xfer


edit:
if hes got the 2.5 he either has the AX4 manual or the torqueflight 904? automatic and either the np229 or 228

[uglyota]

Probably gonna need to source a tranny/xfer before you think about motor mounts...and if you think AA is gonna rip you a new one on those, try pricing their bellhousings and tranny-transfer adapters ;)
does an xj even have room for a v8?

[JeepPhisherman]

several 350s have been done, but by the time you adapt everything and deal with fitment issues, a 4.7L stroker could be just as cheap. but like i said, unless you're racing the thing/mud bogging/ dune jumping, the I6 is perfect.

The real question is, does an 84 xj have room for an I6?

Here's one of Troy's people. "Corvette LT1" according to the description :p

[agjohn02]

yeah, id be more worried about fitting an I-6 in there than a v8. those suckers are looonnnggg.

edit: thats not a "corvette lt1" thats a tpi l98.

[uglyota]

that thing's PIMP!
You'd probably come out ahead buying that instead of building one

[texasxj]

yep i got those "beefy" 30/35-and POS NP207. BUT i got 410's while the 6's dont

already have th350 mated to np231-got adapter from jb conversions $200 less than AA
If people cram a 350 in there I can surely get a 283 in there.

you may be right but I want something smaller than a 350-I only have around a 15 gallon tank in my jeep!! you aint kidding about the 350's though-i love the one in my truck

[uglyota]

well if all you need is motor and tranny mounts, fix that engine and build the mounts, then start breaking axles

[texasxj]

that 283 will definitely snap my little 30/35 shafts and smoke my 31's/32's bald!!!!

[uglyota]

yeah by the way, why don't you get 4 matching tires?

[texasxj]

are you talking about the at's-well its just sitting on those baldies-why get flat spots on my brand new muds? IT DOESNT MOVE ANYWAY :flipoff2:

[texasxj]

Well all you hardcore 350 guys will be happy. I was going to rebuild the 283 and supe it up a little but it is too far gone!!! parts are undeard of and i would have to bore it out so much i wouldnt have any block left plus it has been rebuilt already and the company is out of business-wonder why!!!! New plans: guy that was rebuilding 283 has a 98 vortec 350 so we are starting over-now time to start stripping the engine compartment to make room for a 350!!!!! Watch out ben you got some competition!!!!

[BigRedFord04]

Gerthy!

So are you saying that you think you're going to have to "make more room" for a 350 over a 283?

[texasxj]

somewhat more room-bigger heads, all chevy small blocks have the same core size but defitnitely a 350 takes up more space than a 283. plus have to make room for bigger radiator and lots of other cooling stuff

[junior88mj]

i have swapped a 4.0 in the place of a 2.8v6 in an 85 xj you have to cut out the radiator support from a 4.0 xj and weld it in the place of the 4cyl or v6 support and beat the fire wall back about an inch by the rear of the intake and the cross member holes dont line up either you have to redrill them an make a nut plate to put inside the frame ,,, the front drive shaft will be to short and the rear to long unless you have a doner xj that was a 4.0 need any more info on xj's i only own 5 of them and one mj at this time send me an pm

you have no idea what you're talking about do you? I will bet you 5 million dollars that a 350 has the same exact outer dimensions as a 283.

[savvyaggie]

thanx...

[Fredo]

thanx...

what, you think I'm wrong?

[savvyaggie]

what, you think I'm wrong?


no, thanx because I am agreeing(4 pointing that out), there is no difference from a 283-400ci.

yep all the stuff is coming out-there is so much wasted space in those compartments. will be getting new custom driveshafts-scrapped np207 and rear pencil driveshaft-with 8-11" of lift i will definitely need new driveshafts
