Getting the 66 3/4 ton back on the road

[BAMBAM66]

Hi Guys! have been on browsing this site for much needed restore help.
Have learned a lot and look forward to sharing what i know.

My pleasure is a 66 C20 with small block 350, 4bbl qjet, 3 sp granny with shift moved to the floor. 1st PO started rebuild and sold it I got from second restorer that added the Cragar rims. Bought for wife as anniversary gift in 07 but was in the middle of our house remodel that would not stop. Now she is ready for me to make it GO!!

Over the years I have replaced brakes system, brake and fuel lines, drums front and back, axle bearings and carb. Thanks to this site have properly wired alternator and HEI ignition. Have some play in steering and shifting is hard but is drive able.

Now what i am struggling with is I want add dual exhaust with headers, I have the magnaflow 16643 stainless exhuast kit and a set of ceramic coated headers,which hit the tranny Xmber on passenger side and the clutch linkage on drivers side. I was thinking of using a Xmber with a double hump from a later model GM truck. I am out of my knowledge zone on this, some advice will be appreciated. Oh BTW! My wife named her BAMBAM!!

Welcome to the forum

It sounds to me like you have a set of car headers. Those will likely never work with the original bellhousing crossmember and with a manual trans. There is not a different bellhousing crossmember, they are all the same. Just get a set of headers designed to fit the '63-'72 trucks with a manual trans. The ones that are designed to fit are Hedman #69260's. The coated Elite series are #69268. Some guys will use the later model truck headers such as the Hedman #69090 or the Hooker #2452's. They are a litle tight with the clutch bellcrank, but they will work, have larger primary tubes, and are a little closer to a tuned header.

If different headers are not an option, you will have to change the bellhousing and trans to a later model style that uses a trans crossmember. Either that or go with an auto trans.

Thanks Captain Fab for the reply and insight. I have been to excited on this project that I have rushed some decisions such as these headers. Future plans are to replace the granny 3 with a T-5 or T 56.
