1990 1/2 ton Silverado specs
My neighbor has a 1990 2wd Silverado with a 350.
My question is... does this have vortex heads? And what auto tranny comes in these. I see that it has overdrive Thank you |

Vortec heads didn’t come out until 96. All 87-95 tbi engines have centerbolt valve covers.
Your transmission is a 700R4/4L60. It is not electronic. |
