Re: Engine number decode

Any more info on the motor? I can't find anything with TTJ except some later 400s that wouldn't make sense...

Re: Engine number decode

No thats the only number i can see as the other engine number is down the back and not enough room to get in by the bulkhead. I do believe its not the standard engine for the truck. I think its a 1979 400 lump. Its had loads done to it with edelbrook heads etc..was just trying to confirm as i need to replace spark plugs etc. I no its mounted to a th400 box.
Cheers
