Information about Oldsmobile V8 engines
In this video I talk about the "late" Oldsmobile V8 and offer tips on how
to identify them by number.
"Late" in this instance means 1964-1990. Early('49-64) Olds engines are an
entirely different block, etc.
Sometimes my info gets a bit twisted when it stays inside my head for a
while, so a correction is that '77-80 heads are 3A, not 4A. 4A heads are

Late 307 and 260 ports are half the size of any other versions.

Hello to all those Oldsmobile fans out there!!!
This is my first engine build and also my first ever YouTube Video, so

Also added an HEI distributor and R46sz plugs for easier starts and
hopefully better fuel economy on high octane(91-93). Ask if you want
details on the motor or anything else, Bill
