I6 header questions

my stock in take plate that separates the exhaust and intake has got a hole and wont run now. so i got a Clifford in take and split headers they came off a 57 farline i was going to thru to put them on my 57 f1 to night and was wondering if their would be any issues with Clarence the motor mounts clutch or any thing are there any difference bewen the car header and the truck header will it work?

 

I believe the trucks have the motor mount on the front, while the cars are on the sides. So the car header goes around the motor mounts, and the truck headers go straight down.

 

i haven't put headers on the older style of inlines, but the newer 292's i have put them on were a PAIN! both the ones i have done have had small clearence issues and mounting issues- took some milling and some "massaging" into place. good luck. hr

 

Yup - Unfortunately your experience isn't a rare one. It's rare to have inline six headers fit nicely right out of the box. Sure they'll bolt up... but the build quality on most of the ones i've seen are pretty spotty. For what Clifford charges they should be ashamed too.

The only inline six headers i've seen that were "nice" right out of the box were the ones (pick your brand) for the newer 4.0L Jeeps. Anything older like a Ford 300, Chevy 292, etc will need to be massaged to make them a "nice" header. I've always had to port match and had someone finish off the welding around the flanges etc. Beefier collector flanges should be a requirement. Those suckers warp on every set of I-6 headers i've ever dealt with.

To rollin on heels... good luck with that 6, they're a blast to hotrod and you may be surprised at your results. From a guy that's kinda specialized in hotrodding Jeep and Ford I-6's... headers sound great with an original Flowmaster 40 for a V8 like sound, or a (I know this sounds cheesy) a tractor muffler from Tractor Supply. They sound better than Smitty's and cost only a couple bucks. They're heavy construction too... the Internation Harvester mufflers sound the best in my opinion and they'll give you an old fashioned 6 sound just louder. They are a similar construction to what would've come on most I-6's before 1960, they're just louder. Everyone that's ridden in my Willys pickup with 226 flathead 6 LOVES the way it sounds and it's got a tractor muffler on it.

I would also agree with Circle K on his observation.

 

Thanks for the info tips. Thinking about what cool muffler would sound good on a cammed up 330 Ford

 

oops !! 300 Ford

 

I did it two ways. On the 235 in my '53 Chevy KingCab pickup I used cast iron split Fentons. They fit fine.

On the 230 in my '36 Pontiac I built dual custom tubing headers.
