I googled that casting # from the rear and came up with a 78-90 truck motor, hope that helps.

I could not find a THJ either. This is the closest I came.

THere will be a date code cast into the block, back on the bellhousing flange. It will be a letter and number code. The letter being first. The letter A is the first number of the alphabet, which corresponds to the first month of the year. The next number(s) will be the day of the month. And of course the last number will be the year.

Is this engine a TBI or is it carburated? Or did it even have an intake on it?

The casting number of the flywheel for a 454 with a 2 piece rear main seal is 3993457N
