2.8L swap out

i have a 1986 cherokee that has a wet and tired 2.8L v-6 with an automatic transmission (havent look to see what kind). i have heard that a 4.3L chevy v-6 is a direct swap. well if a 4.3L will bolt up to my transmission then wont a chevy small block bolt up too ?

99% sure it will not bolt up. 2.8 is a 60 degree v, while the 4.3 is a 90 degree, apples and oranges as they say

wont bolt up

Nope, won't bolt up....the tranny is a A904 chrysler variant...the bellhousing is a "small chevy" pattern....a variety of GM 60 degree v-6's or 4 bangers will bolt up.....but the best and easiest swap is a 3.4 V-6....use the intake, fuel and ignition systems from your 2.8....the only snag is you will need to have the stock flexplate zero balanced....any good high performance auto machine shop can do that for a few bux.

Search 3.4 swap........

not that i like chev v-6's, but has anyone tried putting one of those 3.4 DOHC's in a XJ. i know it is not the best motor. but it would be a interesting experiment. or maybe a turbo 3.1 from a gran prix?
