I was wondering if anyone has upgraded their cam from stock and what effect it had on driveability and mileage. I have a 85 K20, 350 4b with a 4 speed manual (1st is granny gear) Im not sure what the ...
I have had nine different small block chevys/gm motors. All fun and easy to work on make additional horse power.
They were 283's in a flat fender jeep, 63 Suburban, and 60 El Camino. 305 in a boat. 350's in three pickups Buick Rainier with 5.3 And the winner was 1967 Camaro SS350 which was 295 HP with 10.25 compression ratio.
The 76 K25 Chevy got a Competition 260(maybe 268) cam advanced four degrees and headers. It ran pretty well.
