Can somebody trace these numbers??

D90E-6015-E3A Z BELOW THAT HAS A 8E23

This is a 79 block but I've tried lineing up the pulleys that came with it and the don't line up. The pulley's are v belt and it had what looks like an early model water pump on it. I bought a front cover for a late model 302 and a 79 water pump, which goes to the driver's side, and the pulley's won't line up. I tried to put the early model water pump and its the same thing. Do I have the wrong pulley's, wrong timeing cover, what???

Also I've been hearing that this motor is a 50oz and then bubba tells me its a 28oz motor and I'm going freaking nutz!!

I know I should have done more research into this but you know I got the car and just had to go! To top all that off the 351 I was going to buy for dirt cheap go sold before I could buy it.....what a day

I have seen a couple of different thickness of front balancer on 302's and that might be your problem.Take a straight edge and measure the difference in offset between the front of the balancer and the mounting surface of the water pump.Then go to a wrecker and grab the pullies off something with the same measurement.302-351w-351c should all interchange as far as bolt pattern and center hole size but watch out for the early 3 bolt pullies.If you don't have power steering then that might be a problem as well as the manual steering cars I have seen used a different water pump pulley without the deep backspacing of the regular pulley.

Your problem isn't with the block. It's with the accessory drive setup. You need to get all the accessories from one motor, i.e.: timing cover, water pump, and all the pulleys. The block casting #'s have nothing to do with your problem, other than you're relying on them to tell you what car it came from. The casting # doesn't necessarily mean that the block came from a 79 car, it could have been installed in a pickup truck, Lincoln, mustang, or any other Ford or mercury vehicle produced from 1979 to around 1984 ( when Ford revised the blocks to use one piece rear main seals.

The numbers would help me to figure out if the motor is a 28oz or 50oz motor right? The idiot that sold me my clutch/flywheel assembly goes by parts numbers and they don't tell him which weight he gave me and I want to make sure I have the right flywheel/dampner for the engine.

most likely it's a 28 oz/in motor, but could conceiveably be a 50 oz/in too. If you can access the crank, that would be the surest way to tell.

what would I look for on the crank to tell me?
