RamHorns or Headers? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

thirdstreettito · 10-05-2008, 10:46 AM

Well, I am about to buy the truck in my sig from my brother for hopefully 300-500$. It has RamHorns on it. I know the old hot rodders used RamHorns. I want to know, what will give me more power? Headers? or RamHorns?

I've always read that ramhorns are one of the better flowing exhaust manifold designs. Do they flow as much as headers? I don't know...but if you've already got em and they're in good shape, I'd run em.

Old Chevy Mech · 10-05-2008, 11:11 AM

From what I was told by the man who built my engine and built $50K racing engines, headers will not give you anything worth the extra cash they cost, until you get into the 8-10,000 rpm range. Ram horns are just fine for most applications, according to him.

My experience also lies in the older equipment I own, CAT 4 cyl diesel exhaust is basically a center dump, my 1936 CLETRAC is a center dump, and my old International I-14 has a center dump. Most Industrial, hard working equipment engines seem to have center dump exhaust manifolds. There has to be something to it. Oh I am sure there's some techno data that says you can get a tad more here and there with their product, but all these companies have a wealth of experience to support their decisions.

Boils down to the budget if you ask me.

For street applications rams horns will do fine. The headers will get a lot hotter, and can be a PITA.
What are your plans?

hotrodhomi · 10-05-2008, 11:16 AM

if your not pushing tons of HP you won't feel the difference.

**special-K** · 10-05-2008, 12:17 PM

Headers are just

.

gator2511 · 10-05-2008, 02:16 PM

I use the vete fuel injection ram horns on my truck. The are a larger diameter inside and flow better than the standard ones. For a street truck I think they flow very well. If they were good enough for a fuelie vette, they are good enough for my near stock motor.

**WorkinLonghorn** · 10-05-2008, 03:02 PM

My understanding is that there is a reason why truck rams are smaller,and that is to raise the low-end torque. Same with the intake. For a stock motor I would go with the truck ones. I could be wrong tho, I've never had anything else.

**70cst** · 10-05-2008, 03:36 PM

Interesting...again I continue to learn off Chevy Trucks 101.

big_al_71 · 10-05-2008, 03:42 PM

Headers all the way for me..look better, perform better...

thirdstreettito · 10-05-2008, 07:14 PM

Thanks for the info guys. I'm gonna keep em, get em ported and polished for better flow. And hopefully run 2 1/2" - 3" straight pipes with glasspacks dumping at the 2 piece driveshaft cross member.

Engine plans = Edelbrock 575 Carb, Edelbrock Torquer intake, all aluminum heads, serpentine system, "raised" CHEVROLET valve covers, dual air plenum intake, dual electric fans. Built to about 375-400HP. Total price = about 2500$ Oh yeah, and a built TH350 with 3:42:1 posi.

**special-K** · 10-05-2008, 10:47 PM

Which intake,the Torker or the dual plenum?The Torker is open with straight runners for high rpm torque/high rpm flow.This is a manifold that benefits where the headers would also.
If ramshorns are adequate for the motor then so would 2 1/4" duals.Any motor that would run best with 2 1/2-3" exhaust would run better with headers,too.

thirdstreettito · 10-06-2008, 08:59 PM

Dual air plenum, it looks like a dual air filter, you know the tubing and whatnot.

Well now maybe I'll do some more research into intake manifolds.

Oh and a Lunati street cam.

drivethechevy · 10-06-2008, 09:26 PM

i like the rams i think they look much better then headers, im not 100% on the resoning but in the stock modified circle track racing that goes on around where i live, the races always run rams or a version of the rams, im not sure if they are regulations teling them to run them, but 100 laps at about 80-130 mph on a dirt track rams work better then the cars that do ocasionaly have headers

msgross · 10-06-2008, 09:28 PM

so did you get your license then?

thirdstreettito · 10-06-2008, 09:40 PM

Nah not yet, Jan 4th and I will.

My brother just talked to me while we were playing a video game online, he will sell it to me for 500$.

Thats is 200 less than before and 165 more than I have now.

I am so excited. I'll post plans for the truck tomorrow.

msgross · 10-06-2008, 09:44 PM

I would just plan on keeping/getting it in good running condition for now then. Save money for gas and girls... The trruck will be there for upgrades for awhile...

5150.4.67 · 10-07-2008, 01:42 AM

Yeah, just get it together and drive her for a bit. Match port the rams if you like. You can always change to headers later. Performer rpm intakes are hard to beat, IMHO.
