engine advice 1984 firebird
I have a 1984 firebird with a 305/700r4 combo that stopped working on me right before winter, im looking into purchasing the l33 and attaching a 4th gen firebird/camaro 4l60e transmission to it. i wanted to get a 5.3 but most of the ones on kijiji are lm7's, i was wondering how i could differentiate between a l33 and an lm7, is there any distinct physical characteristic that sets the two apart or do they look almost the same?
Thanks
