I am seriously considering buying a new crate engine for my car. The present engine is not original to my car so I don't see any advantage to keeping it. I am wondering if my present block and heads have any value that would help off-set the cost of the new engine.
The stamp pad number is FII20HF along with 5103333. The casting number on the left rear is 3782870. The head numbers are 3782461 with K104 just above it.
FII20HF The F indicates Flint, II letters were used instead of numbers 11 = November, 20 is the day of the month, HF = 1965 327/300 horse power w/ manual trans casting number 3782870 is correct, 5103333 should be a S103333, that is 03333 serial number should be the same as your last 5 digits of your VIN number, heads 3782461 are camel hump should have 1.94 intake valves & 1.50 exhaust valves correct number with K104 is the casting date A = January, B= February and so on, 10 is the day of that month, 4 is last digit of the year 64.
Looks correct to me, that’s if you have a 1965 Corvette..... if not I'd advertise it here on the forum if it's running 1,800 is a good start, good luck!
