4.3 v6 headers?

Anyone know of a manufacturer that makes headers for a 4.3 v6 in a 67 c-10 2wd with floor shift manual trans?

Nope. Maybe some later model headers, lik 88-95 truck headers with a 4.3 would work. Not sure........

Maybe some for the 4.3L V6 from the s-series would fit, have you tried the major brands yet? And craigslist.com and ebay.

Re: 4.3 v6 headers?

i agree with either S-10/ blazer header or truck, would use truck though they have better choices and better bends. Wanna see a rad 4.3, check out my buddies 4.3 on campbellautomotive.com

Re: 4.3 v6 headers?

Yeh, headers for the S-series would be tight against the block for if they were used in a S-series. Might not be a bad thing for what your using though. I cant remember for the life of me who made a great set... Thats if the modern 4.3L headers fit the older one...

Re: 4.3 v6 headers?

Thanks for the info guys. There is a place selling 4.3 header flanges on Ebay. I might just make them but I was trying to save time.http://cgi.ebay.com/ebaymotors/ws/eB...8158221&rd=1,1

Re: 4.3 v6 headers?

They did not make a 4.3 (262 CI) in 67. If someone put one in from a later model, then as mentioned I would think the headers from the later model would clear the frame areas. Problem you may have is if you are using a z-bar (original) style clutch vice the hydraulic used on the newer ones.

On another note the later model V6 (4.3 ) is a 90 degree V6, while GM's earlier models were not. I if memory serves me right I believe they were 60 degree models. This means the header flanges and piipes would probably not set or route even close to correct.

The 4.3 V6s are based off of the 350 sbc and are all 90degree blocks. The 2.8, 3.1, 3.4v6s used in the cars and S10s are 60degree.

Re: 4.3 v6 headers?

I have long tubes on my 4.3 V6 S15 Jimmy. They tuck up reasonably close to the block, close enough to make changing spark plugs nearly impossible anyways, . I have no idea who made them, as they came on the truck, but if you want I can see if I can get a good pic.
