165 MAF computer

[Shannen Durphey]

I'll vote with the horsepucky crowd.

383ci, 58mm TB, supperram intake, headers, AFR heads, 3.73:1 gears in an 86 Y
body that does mid 12's, and diacomb reports 255 gps around maybe 3500 ish rpm,
and stays there right up to the shift point at 5000 ish.
And definitaly 165 ecm, running well modified ARAP code.
