Hi guys,
Just come across this 390 $450 obo.
it was pulled from a thunderbird in the eighties, my thinking is to buy & gradually do a rebuild over time, then put it in my 68 fastback gt390. Would this work?
what questions do I need to be asking.
can someone tell me what the engine tag relates to.
cheers Mark.

Not much use. The heads will have to be replaced, and the intake manifold, and the pistons, and the camshaft… So basically you'd be buying a block, crankshaft, and rods.

(The heads are the wrong exhaust pattern for a Mustang/Fairlane application.)

Also the exhaust manifolds not fit. Believe those would hit steering column on that side.
Also on that tag, where it says "311", should be "322" engine code for a mustang 390 is what that is. It's on my orig build sheet for my 67 390 GT.

The tag tells us the engine is built to 1967 Thunderbird specifications 311 Revision A. Not much except the block, rods and crank would be the same as a '68 Mustang. Depending on whether you care anything about date codes it might not be the best for you.
