If it's a four speed auto it's either a 700R4/4L60E or a 200 4R. Charlie gave you the pictures for ID.

For the flat tappet engine you'll want some type of strong zinc additive, like ZDDPlus or something similar. Even better is running a racing oil, like Brad Penn's or others that carry high zinc. Sorry, I cannot help more with your engine details from the numbers.

No that's great! What if I put the zinc additive in and it's not a flat tappet cam. Can adding high zinc cause any problems?

Nope, zinc & zinc/phosphorus are good stuff, focused on high pressure wear zones. Adding Zinc, or running the oil with high zinc is not a problem for any engine, but it's become all but mandatory for flat tappet, non-roller lifter cams.

Great! Zinc it is! Any other newbie tips for a wanna be hot rodder?
