THERE WAS NO CORRECT INFO GIVEN IN THE FOLLOWING POST AND i TRIED TO ADDRESS AS MANY AS POSSIBLE Ken, the 360 that Chrysler made is the same one they use now in the Jeeps and such, as long as it isnt the truck block it will fit in your Gremmie, CHRYSLER 360 ONLY FIT CHRYSLER NOT AMC frot shocks and springs will need to be a heavier type bacause of the weight difference between the 6 and 8 cylinder engines. SPRINGS ARE RATED STIFFER FROM 6-8 WITH A/C SPRINGS BEING STIFFER WHAT LOOK YOU WANT IU RUN6CYL A/C IN MY 401 GREM if you want a good 360 look in an older Jeep cherokee about 1974-79 it had the ford intake and chrysler exhaust on it and is still a powerful engine THERE IS NOTHING CORRECT HERE EXCEPT IT BEING POWERFUL , the 401 is basically a Chevy 400 punched out to a 401 and because of this is a weaker block. WHAT!! HOW DID THEY GET THAT DIST TO FIT AND WHY NOT PUT AMC HEADS ON CHEVY MOTORS IF THEY ARE THE SAME SINCE THEY FLOW BETTER the T-10 will fit the standard rear end as long as the splines in the tailshaft and driveline match, WHAT DIFFERENCE DO THE SPLINES MAKE? ANY DRIVE SHAFT CAN BE MADE IT'S THE YOKE THAT MUST FIT THE SPLINES AND IT IS REMOVABLE if you buy a T-10 from a wrecking yard, grab the driveline if possible, you will need it. LOT'S O LUCK WHY NOT GET THE FORD TREMEC 5 SPD IT'S A LOT EASIER TO FIND AND BOLTS UP USING LATE MODEL BELLHOUSINGS as far as the front brake conversion, Bendix makes a conversion kit that you can get from a hot rod shop, its a bit pricey but if its what you wanna do then thats how I would do it, short from robbing a Monarch of its spindles and things WOW ALL THESE AMC WITH DISC'S LYING AROUND THAT JUST BOLT UP AND WE NEED TO PUT FORD PARTS ON AND BUILD ADAPTORS TO MAKE THEM FIT SORRY I'LL USE THE STOCK BENDIX BRAKES (sorry Bart :-) ). aside from that have fun on your car and will talk to you later.
