The Stovebolt Site Forums The Parking Lot Big Bolts 42 GMC COE Manifold ?

I checked the stamping on the block. The engine is a 248.

Trucker,
The truck is a lot of Fun. I bought it early this year and drove it 100 miles home (SOLD my tow rig and had not bought another yet).
I actually enjoyed the trip though. Just could not get in a hurry.
