I am looking at a 99 zl 440 that needs a engine, I know my buddy has a few early 90s 440 engines but I am wondering if they will fit or if the block was changed to accommodate for the newer mounting style. Any help would be great.
What do you mean by it needs a engine? If the motor is destroyed but still there, a number of motors will fit. That being said you will need to use your exhaust, carbs, stator, flywheel, etc. The mounts off the motor in it should bolt to the older 440's. If you have none of the above it will get a little harder. The pipe for most motors was matched to carb tuning and the timing to the cdi. The pipes were normally made to fit in the specific body style also.
