350 swap?

[4ward]

jahleman, yeah, I meant to say LT1 is only 80 lbs. heavier blah, blah, blah. I think you folks could figure that out on your own though :geesh:

5-90 was the whole front clip lengthened or just the header panel changed around? Still the same front fenders correct?????

LT1 & Carb? is it from the early 70s?

Corvettes in the early 70s had the LT1 badge, but all new ones have MPFI.
My setup is MPFI, 8 Injectors, and a 4bbl 1000cfm throttle body.
And it is a good point about the frame holding up. Sometimes you get a Friday Afternoon Jeep and sometimes you get a Monday Morning Jeep.
I did my V8 swap in 1995! I drove it to Alaska and back with heeps of weight. I probably have 85,000 miles on this motor/setup (with 5" of lift and 33", new lift/tires was this year)

Hear/Tell you have to cut the radiator support on pre 87'
But I dont know fer sure. Then kinda relocate it.
Mine is a 87 and I didnt have to do it

well. I know that earlier fenders fit an 89 XJ just perfectly

from what I could see by comparing the two side-by side (85 2.8L XJ vs 89 4.0L XJ), the sheetmetal immediately behind the header panel is different, and the firewall is slightly different as well. if you were to drill out all the spot welds on the core support and swap in the newer sheetmetal + massage the firewall with a BFH, it seems you could easily swap in anything, even a 4.0L!

,.I have repeatly argued that ALL model years,.of the XJ are about the same, for example on the 1985-86 with 2.5 liter-2.8 liter engine,.the additional engine compartment space ,lenght , can be found by merely cutting off the radiator supports and a small amount of metal on the front sides with your personal choice of cutting tools,..and voila ! Position your new 3-core or Be Cool or Superior Radiator,..etc over the forward most crossmember and you are good to go with I-6, Ford or in my personal preference, the light aluminum head Chevy 350 V-8 LT1 ( the 1995,..not the 70's version)- Want to change the 86 front header panel to the 1997-02 look/design,.not a problem,..rear hatch,..,...?
