Headers for a 4.3L
 

Well i just bought an 86 monte carlo with the 4.3L and i going to build it from top to bottem converting it to carb (is possible). 305s ar way too over used in my opinion so i decided to stick with the 4.3L. Now my question is, is who makes headers for the 4.3L i have checked the usually place such as edelbroke and heddman coming up with no luck. I would like to be able to get long tubes. Any info would be greatly apreciated

I think your going to find it difficult to find performance parts for your 4.3L and may have to look towards custom fab in some cases. Here are two links to some 4.3L builds that have source info on the second page that may or may not be of use.

Not a problem....

Keep us in the loop on your mods....


Those articles show that it is possible to get quite a bit of power out of your 4.3L...

the setup they ran was pretty much right down to the teeth of the part i got sitting in my shop. there cam setup was a little bit more aggressive with over .500" of lift. The setup i will be running is Duration 268/ 268, Lift .454/ .454. I should be up in the 250 horse range N/A. I have plans for that vortec supercharger ass well down the road. that should push me well into the 400's. All i have to do now is wait for some warmer weather and really tear into it. It sucks not having a garage.

I question i do have, though its not an exaust question but i cant find a fuel pump for the damn thing taht i know for sure will work. Im assuming i a can a mechanical fuel pump from a v8 any ideas??

If all else fails, go electric aftermarket...


Is this going to be a daily driver?

Wonder if the 4.3L truck fuel pump is the same use on the Monte????

Its going to be for sunny days only. i have a truck for the rest of the weather. its going to be carbuerted and i didn't think they made an electric that would wrok its gonna be like 6-8 psi. i'll have to look into it more. im sure it would work cuz it just has a block off plate on the side of the block now so i would assume it would work

well what do you know. during one of my trips to the can i was looking look at my summit catalouge and found a holley fuel pump made for carbs. well i'll be jiggered. Carbs are new to me every car i have ever work on has been fuel injected but i decided to go old school and run the carb
