The bottom line is ... ... He asked about the difference in Ramhorns and Sandersons ... not real headers

Sanderson makes real headers not just block huggers

I apologize for the quality of the pictures, the car was being wet sanded prior to paint so it's pretty messy.

As I mentioned a few nights ago, I had bought a set of Sanderson Headers on ebay from a guy that goes by the name of Nova Joe. I contacted him today and he's still selling them and in fact has a contract with Sanderson. You can contact him on his website www.novajoe.com. He is still selling the ceramic coated Sanderson Headers for $325. to your door. Below is a couple of pictures of my '32 with the Sanderson CC5 headers that gives ample hood and spark plug clearance. Hopefully this will save some of you guys some $$$

I thought he was comparing RamHorns to these Sanderson iron exhaust ... more of a apples to apples comparison ... not a apples to oranges comparison.

that is not what I deduced from the title of the post, it states "ramhorns vs Sanderson headers"

Please advise me on these 2 different styles of new and cheap (probably Chinese) ram horn manifolds.

I'm thinking about them for a bone stock 1991 305 TPI engine I'm putting in a '57 Chevy pickup for my wife to drive for errands.

Wow. Hell of a deal on these.

Would these gain me anything on a stock 305 TPI? to justify the extra cost?

So, this is the reason I'm looking at the rams horns:



These cheap stainless block huggers I bought on ebay won't fit. I've got the new CPP 400 power steering box and they obviously not very header friendly. Sanderson's has a couple of designs that will fit but they are expensive. Those JBA's will fit too but I'm not sure about the port shape because they are designed for LT1 type heads.

So, I'm leaning towards these ram horns:





I'm pretty sure they are made by Wysco Products. I think the castings look better than the Dormans.

Comments?

For that truck I'd use a set of 1993-97 Camaro/Firebird LT1 or 1994-1996 iron head LT1 manifolds. Or even a set of IROC-Z manifolds with their 2 1/4" exit manifolds.

1993 LT1 F-body manifold


94-96 Caprice manifolds 2 1/2" exit


These have D ports though, the exits look perfect though.

p.s. ratrods and half assed traditional hotrods suck

It depends on what you mean by "half assed" many "uglier than sin" cars run wicked fast times, they just spend all their budget on speed rather than paint and chrome.

BTW Round Rock, TX is in one of my favorite areas of the country- you lucky SOB.

Thanks for your reply and help.
Sorry for the misunderstanding. My engine for the truck is a stock L98 305ci TPI out of a '91 Z28 and doesn't have D ports. I'm thinking that the rear exits on those manifolds might be problematic too. I know the ones that come straight down in the middle will work easily.

I've been doing a little more research and have found some information about the flow of these that is real interesting. The old 2 1/2" cast Corvette versions of the ram horns flow just about the same as headers up to about 6000 rpm. But, the standard 2" outlet versions do not. I saw a dyno chart where this was documented.
Since my displacement is only 305 and my rpm will never top 5000, I think it's a given that the 2 1/2" ram horns won't hurt me in any way.

I've pretty much decided on getting the Wysco 2 1/2" ram horn reproductions that I posted the pic and link to above.

On a bone stock 305 you're probably only giving up about 25hp/25ftlb... if it is modified in any way those numbers can start to quickly escalate.

Manifolds give up a LOT in the power department, and its not just because of flow, manifolds have no scavenging effect and if you have a larger cam they can cause a lot of unwanted reversion.

If power isn't a concern though a bone stock 305 with stock exhaust manifolds will still run just fine, its ran that way in millions of cars.

I don't think so. Not with the 2 1/2" version and lower rpms.

Take a look at this dyno info:

Dyno results - headers vs rams horn manifolds - ChevyTalk --The Social Network for Chevy Fans

Looks like it's only 5hp/5ftlbs difference at 5000 and below and that was with a 383.

But you are pretty close with your numbers if you compare the headers to the 2" ram horns with the 383.

Another thing is that for my case, I would also be comparing block hugger header style to the 2 1/2" ram horns on my 305. Block hugger are not going to flow like full-length headers. So, I might not really be losing hardly anything by going to the 2 1/2" ram horns.

The flow is only part of it, the harmonic tuning can have a HUGE effect on power, ram horn manifolds are not tuned.

Compared to block hugger headers though you won't see much of a difference, there will still be some but probably not more than 10 ftlb.

Again, it doesn't appear that power is a concern and there's nothing wrong with going with what is cheap and fits.
