one exhaust rocker was not contacting the push rod properly. the rod the 4 rockers were mounted on had a slight bend. swapped it and runs smooth now

i removed the original ac box and have one here for an s10 truck. just need to fill the old mount holes and drill new ones as they don't line up

[diaric]

i'm not sure which turbo it is. there's no id plate on it like other gm-x turbos, just a serial number

[Vinnie305]

just a serial number is a gm 8 the newer turbo

how are you planning on routing your exhaust

[Vinnie305]

just a serial number is a gm 8 the newer turbo

did you ever figure out what the thumping was?

[flo160]

do you have AC? did you get that engine in your engine compartment despite the AC box?

Great work on that engine!
