Xram53,
Thanks. The reference the I have is for light trucks, so the Sedan Delivery (1500 series) is listed.
Looks like the engine was changed at sometime but it could have the original Hydra-Matic (or maybe the Powerglide) in it.
Am I right to think that the major difference in the engine (besides its blue color) is that it has hydraulic lifters (and maybe a different composition timing gear)?
Thanks,
Tim
