Im sure this is a beat up question and old but I have a engine that is confusing me as far as being able to ID it . The block casting number is 3914678. Build date stamp shows E-28-8. The partial vin is 18J284645 and the engine ID is V053THH or V053IHH I'm pretty sure its a "T" but you never know.. Everything I find says its a 350ci Engine But I keep finding "HH" listed as a 1969 engine for the most part. I would greatly appreciate any help.
