straight vs. angle dump ram horn exh manifolds
What trucks are suppose to have which exhaust manifolds? I saw a 307 in the yard today that had straight dump manifolds, but was thinking that most had angle dumps? Can anyone shed some light on that.
Thanks Brian |

See already we have conflicting information, hence the questions....
Stocker, are yours original and what year / model / engine is your truck? Classic heart beat shows angle dump....I believe LMC shows both angle and straight, but I don't think they clarify which is used in what appliation. Keep the information coming.... thanks Brian |

When I bought my 2WD 72 it had angled on the passenger side and straight on the driver side. Who knows if they were original or not. I replaced the straight dump with an angled dump because the bolts were a pain to access on the straight dump.

the 2wd trucks had angle dumps. if you were around back in the 60's(I am that old lol!)....the cars had straight dumps . the manifolds will fit the 2wdtrucks, but it makes getting the nuts started on the ex studs a big PITA! Now if you slide that smallblock in on I 6 stands, the straight dumps will fit just fine

I had an extremely difficult time finding a good driver side angled manifold. I don't blame you for going the header route!

Well it sounds like the answer, by popular vote is, 4x4 = straight, 2x4 = angle. I will have to check that truck in the yard (with straight dumps) to see if it was a 2x4 or a 4x4.
Thanks Brian |
