'71/'72 360 rebuild questions --stroker
Greetings,
I have a stock 360 motor (in a J2000) that I'd like to rebuild if it
looks nice upon disassembly.
Has anyone done a rebuild on one of these with an aftermarket (maybe a Stroker) kit?
The air injection on mine has been deleted; I don't plan on putting it back, for simplicty.
Thanks

71 ? so you have one o the first j2000 with a 360. Do you have a VIN and production date (door jamb sticker) ?
You'll find rebuild kit by maddog (ebay) or others, but unlike the later 6cyl 4.0L, no vendors for a 360 stroker kit. Some have stroked a 360 with a 401 crankshaft though, you should find a post here

From the Data Plate:
J2M241WN13054
The engine # is not in front of me right now;
last I checked it listed as a '71 made late in the year...
'N' ...
Thanks for the input.
Cheers.

Check the crank isn't the flat flange. AMC changed the crank in '72 for 727/9XX trans.

Early 1971 heads are high compression (291c). I think it was around 9.2.
Late 1971 are standard 8.5 compression heads.
The actual performance difference between them is nil.

Somewhere in the 8.25-8.5 range, yes. 1977 will also have 1.5 ratio bridged rockers.

I always thought the stud rockers were 1.6 and the bridged were 1.5. If you look at lobe lift specifications, they increased lobe lift the same time they changed over the rockers, but the 1.5 ratio brings valve liftto the same specification as before.

Here's the difference. '71 AMC cars (AMXs and Javelins at least) got 10.5:1 compression option. (photo isn't mine. It's "borrowed")

they were all 1.6. but i believe there is a listing from amc for 1.5 in one or two years,but i've never seen them or had someone say they had either. maybe some emissions application for california or something. i'll see if i can find it.
the cam changes were more likely for epa regs.
