I want to add some headers and h-bar exhaust on my 77 f-250. Can anyone recommend some good quality and high performance headers and exhausts? Also i have a question totally irrelevant but, say you have a tire size like 235 75 15, how do you get the rim width out of that?
Thanks

 

also a good carb.

 

Hard to beat L&L products for early 460 headers. Carb depends on how your engine is built, but not less than 750cfm. Rim size is dependent on rims, not tires. 8" is the most common.

Thanks!!! Ok, say you have a 9.25 inch wide rim, what is the biggest tire width that could go on the rim?

 

the man is right

L&L are the best of the best

 

Unfortunately I don't have it with me, but in the tire section of Jeg's they have a tire/rim size chart. I will try to post it when I get home tomorrow.

Heh heh heh....I love the cherry bombs behind my 460 with L&L headers coupled to 2 1/2 pipes to 3" tips.....some other crummy S-10's might not..... I think a few local police have taken a second look at me as they pass tickets out to others on the other side of the 4-lane....

 

While a lot of people like the sound of glass packed mufflers, they're 50-year-old technology. Heat soon burns up the fiberglass and they do get louder. Much louder.

Flowmasters are extremely popular, but they're 20-year-old technology with some of the highest back pressures available in a muffler. As they have the largest advertising and promotion budget in the muffler business, they sell a lot of mufflers.

Much automotive technology is handed down from the aircraft industry, and mufflers are no exception. In the past few years EPA noise abatement legislation has forced the small aircraft industry to rethink exhaust systems. Engines with FAA rated horsepower were required to switch from no exhaust to a mufflered system. Some of the inovations include straight-through mufflers with baffled chambers that greatly reduce the noise without creating back pressure or reducing hp.

Current drag and puller racing rules have also adopted noise abatement policies and many of the racers are using the baffled technology. Blown big blocks using 3" exhaust systems and the new mufflers are meeting abatement rules of 95 decibels. That's less noise than many people produce with their stereos.

Sound is usually the preferred benchmark for most people's exhaust systems, but if you want top performance and the ability to hear your stereo, check out some of the new racing mufflers.

Can you suggest any particular brand(s) in particular that use this
low-restriction technology?

These products have been touted on the 385 forum. I have no experience (or affiliation) with them but am going to use a set on another vehicle I have that's going from 2.5" to 3" exhaust.
