Which exhaust manifolds are correct for 69-70 307?
Ramhorns or rear dumps?
Thanx Dano

Hey jsbgump
The reason I ask is because Classic Industries shows only rear dumps as replacement manifolds. Which ramhorns? Straight down dump or angled back dump? Thanx Dano

ram horn manifolds are the ONLY ones that came on 67 - 72 GM 10 - 30 series trucks witha small block engine.
I *THINK* straight dump was 2 wheel drive, and angled dump was 4X4... but I may have that backwards. |
