Good Day, Was the engine an Oldsmobile or Chevy small block? If Chevy then they will probably bolt up to the heads. Then of course if they were from a passenger car they may not have enough clearance, between the collector and the floor.

God Bless, Terry

If it is an actual Oldsmobile 350, then no, they won't fit. If it was a Chevy 350, then they'll bolt up to the heads, but will they fit the truck chassis?

If they are a freebie, then get them and try it. Nothing ventured, nothing gained.

If he wants you to pay for them......unless it's extremely cheap, I'd pass.

My $.02

Olds used small block chevy 305 engines in the 80's. Chance of them fitting your truck very slim. Olds 350 NOTHING like a chevy 350.

from an olds it would have to be 78-87 i think
to be a small block

1tonchevy · 06-09-2011, 04:14 PM

he says they are from an 86 cutlass

motornut · 06-09-2011, 05:32 PM

86 would be right
i would think the bolt holes etc would be further apart
you would know quick
maybe run a part#?
but the BB olds headers fit real tight underneath
my buddys 72 sylark with 3 inch exhaust
