1986 Chevy K20 Scottdale Question

Hi All,

I just recently bought a 1986 Chevy K20 Scottsdale 4x4 truck. The truck has the original 350 small block motor with 106k miles on it....The truck has aftermarket headers supposedly which I am not sure of, but it does have a edlebrock carh 600cfm non-egr, non egr edlebrock manifold, edlebrock air cleaner, and edlebrock valve covers.

My question is what would be the numbers on the back of the original motor so I can do some research on performance parts...Any ideas? I cant read it on the back without totally taking stuff apart. Any info is much helpful. Thanks to all.

if it'se original motor . on the left side of engine(standing in front of truck) on the deck where the head meets the block on the front end of the deck is numbers. the a/c compressor or your alt will be the only thing in the way. and most times you can see around them..
the last 5 numbers should match your last 5 on your vin if original.

1986 truck 350
The four-bolt main 350 with two-barrel carburetor came with 8.5:1 compression, and was good for 145 horsepower at 3,800 rpm and 250 foot-pounds of torque at 2,200 rpm. 350s equipped with four-barrel Quadrajet carburetors produced 170 horsepower at 3,800 rpm and 255 foot-pounds of torque at 2,800 rpm

You can't tell if it has headers or not?
Boost adds dignity to what would otherwise be a vulgar brawl...

stock looking manifolds are stock manifolds. headers are separate tubes for each cylinder. the block codeing number is usually shrouded in sludge even if you CAN see it behind the engine accesories. normally some disassembly would be required to see the number. cant remember what my 86 jimmy accsessory looked like but you probably gotta pull something off to see it.
