assuming that it has a 302 now, any year model 302 will work without hardly any mods. now if you get into the injected computer model, that is a little different story. even they will work easily if you stick with the carb. good luck------------------

I have a 351W four barrel in my 68. When it came time for headers it was really tight. I ended up asking for help from ScottH. He was able to make it fit when I couldn't. If I were changing the engine, I think I would go with a late model injected 302 (5.0L). I used to regularly get about 25 mpg on my 87GT and I have a rather heavy right foot.Craig

A couple of thing to watch for when comparing late model 302 or 5.0 to an early 289 is that the 5.0 have a different imbalance than the 289. Meaning that some of the items will not transfer between motors. Flywheels or flexplates, harmonic balaancers, water pumpsare some. Also if you have a manual trans, the late 5.0 blocks do not have the provisions for the clutch linkage on the rear of the block.Mike
