1964 - 1990 Easy Ids
Easy Ids
Early [pre-68] oil fill tubes had a simple smooth tubular top with a
press-on oil fill cap. Late [68-up] oil fill tubes have a twist-on cap
with correspondingly enhanced tube shape, AND an engine unit number stamped
into the tube, the first digit of which matches the last digit of the year
in which that engine hit the streets [well, model year, you know].
A few more differences:
Early: Late:
1964 thru 1967 1968 and up
Big-neck PS pump Little 1" or so PS fill hole (1971+)
Early pattern flywheel/flexplate Late pattern flywheel/flexplate
SB's= 330 CID SB's= 260, 350, 307, 403 CID
BB's= 400, 425 CID BB's= 400, 455 CID
Block= A, B, D, or E Block= G, F, Fa
Heads= A thru C Heads= C and up
X/W or X/Y xst manifolds W/Z xst manifolds, if lucky
Forged crankshaft Cast crank [99.9%]
45 degree cam required 39 degree cam required
[except .921" lifter BB's] [all engines]
No divided exhaust manifolds May have divided exhaust manifolds
