Hello and welcome to the forum!
Apologizes for the delay in responding!
The number you've posted, F0324TPT, is the Engine Assembly Code.
It decodes as; F = Flint (assembly plant), 0324, date code, March 24, TPT = Engine Suffix Code, this particular code I have been unable to decode. I have found several codes very close to it, FPR, FPS and FPW, they all decode as, 1989, 350 cid, truck, 210 HP.
It's a good guess, FPT decodes the same!
So, it looks like you got a 1989 350, from a truck.
That's a good thing!
This will be a Chevy roller cam truck engine, a lot of HP and torque can be made from these engines, with Chevy components!
This will make your '63 pickup a real go getter!
Good luck with your build and don't be a stranger around the forum, stop in from time to time and keep us updated on the progress of your build!
