You might try looking here at Direct Auto.com
http://store.yahoo.com/dpstore/repai...-350-5-7l.html This listing is for 350 trucks but they may also have the others too.

They did put 454 in corvettes in 71', so I'm shure they are ramhorns out their somewere for them. Im not shure when the 427 came into place with the Corvettes.

ive had both rams horns and blockhugger headers over the past 10 years and i would pick the rams horns any day over the blockhugger headers.

chevyfan420 · 05-01-2005, 10:34 PM

I was told by an older hardcore Chevy guy that ram horns are definatly the way to go.

for what reason?

k-20 · 05-02-2005, 04:36 AM

the main problem that i had with the block huggers was trying to stop them from leaking.they leaked where they bolted onto the heads and also where the engine pipes bolted on to the collector.they was made made by a company called genie.

That link takes you to the "truck" manifolds. Those are all 2" ramhorns which is not what your looking for if you want to improve performance.

Try this page Corvette manifolds and check out the 2.5" manifolds.

And the chromed rams look right at home on it too.

It's no flathead.

BBC's don't have Ram Horn manifolds.

SanitysBane · 05-02-2005, 05:21 PM

What exhuast did the bbc corvettes run?

**Captkaos** · 05-02-2005, 05:39 PM

They ran cast iron manifolds. Rams Horn is a name associated with the look of the exhaust. They "look" like Ram's Horn. They were called manifolds.

This is what a BBC Vette looks like:

Is 2 1/2" the ID or OD of the pipe?

Here is another sorce for Ram Horns:

Here is more info:

http://www.castheads.com/2into1_systems.php

anyone tried 2into1

I would like to run a single pipe to the back just like factory exhaust
but 2 - 2 1/2" into 3" with nice quite 3" in 3" out freeflow muffler.
If there is such a thing.

86swb · 05-17-2005, 08:55 AM

I have been using headers for years and never knew the Long Horns were this good. Never had any leaks with any of the headers I ever had except maby a gasket leak.

Brad_Olson · 05-17-2005, 09:21 AM

OK, from reading the posts and following the links I've come to the following conclusions:

- 2-1/2" ram's-horn manifolds are preferred.
- Any manifold with the straight-down outlet will require engine frame mount modification to fit.
- Manifolds with the angled outlets will fit with no problem, although I'm wondering if this is subject to the truck being 2wd or 4wd.
- There are no new 2-1/2" manifolds with angled outlets.

Am I on track here? Did Chevy ever make 2-1/2" manifolds with angled outlets? If not, I would think that a set of 2" manifolds could be improved by opening up the inlets and then extrude-honing, but this could get pricey. I think I have a set of angled 2" somewhere in the basement...

[It's no flathead.] I know. It's one of Louie Chevrolet's finest achievements!
Ok. flatheads are neat too. But they ain't Chevys.

Brad I think you have it. The 2.5" ramhorns were small block Corvette only. You could port match a 2" set as well, but they won't flow as much as the 2.5".
The angled outlet ram horns were truck only....

**Boog** · 05-17-2005, 11:22 PM

I have my doubts anyone could tell the difference between the 2 and 2 1/2" manifolds by the seat of their pants dyno though Ken.
