I would sincerely suggest refurbing your existing one if you have one. its dead easy. i describe it
here. IMHO significantly better than any of this plastic aftermarket stuff.

Stock is ideal- this rig didn’t have one in the pile of parts. It’s not a resto so this was a solid option.I would sincerely suggest refurbing your existing one if you have one. its dead easy. i describe it

I did the same thing and bought it from redline cruisers. I bought a new OEM fender from the guy in Germany. The fender didn’t have the provisions for the stock canister and didn’t want to drill into the fender.

I have not had one for about 40 years. We have never had emissions here and removed all of the vacuum lines.
1978 was a transition year with stickers that said unleaded fuel. The manual said it would run on any grade of gas.
We did not have many stations that even sold unleaded gas and that was problematic. It never had a CC, so I fixed the gas problem by removing the necked down section in the filler neck so I could use the bigger nozzle.
I just replaced the tank and filler neck and the new neck had the spring loaded gate as well as necked down for the unleaded. That had to be removed so that the diesel nozzles will fit. Then put diesel only stickers above the fuel door and on the dash.

I used the redline cruisers kit as well, happy w/ it. Mine did not have the original canister or bracket, and while I wasn't trying to re-smog the truck, I didn't want gas smell in the garage.

I never had any fumes in doors or in the cab and forgot all about the canister. I reinstalled the vapor separator with new hoses for the new tank. I had to look in the emissions manual to see where the steel tubing went when it left the cab. I was told I needed to put the check valve back but with out any vacuum being pulled on the vapor separator the check valve would never open. It has not been there for so long it is not going back.
So, where does the vapor go from the separator then?

Outside the cab through the steel vacuum line below the vapor separator. It has been that way for most of the time I have owned the truck. If the check valve was not at the canister it may still be on the vacuum line under the cab.

Here is a better drawing from the manual.
Ah, so you have it connected to the vacuum port on the base of the carb, and it pulls direct from the vapor separator.

I removed the stock carb and replaced with a Rochester 2 jet and it did not need one. I did not connect the vacuum line again when I removed the canister but it has been a long time ago when I did this back in the late 70s or early 80s, and I have slept since then. I deleted everything for emissions and and installed a header and never had any issues until I let the machine shop removed 0.050 off the head when they did the valve job. That was fine at 6K' and above but not in the Portland, OR area. I could not get enough gas to it to keep from knocking.
I may have used the vacuum port if it still had one for the Rochester carb. I also have not driven this truck since 1991 and started taking it apart back in the 90s. Now all of the original emissions are moot since I now have a Cummins R2.8 in the truck now.
Interesting What compression ratio did you end up with the shaved head?

I have no idea and I was going for higher compression and like I said it was fine in the Rocky Mountain region but on on the coast time was against me. Work put me up there to make a pay check.
I trusted the shop that milled the head but when I asked how much they were going to take off I go "I don't know I will look it up". I was in College at the time to get back into the workforce and didn't have much money.
Seemed like anything I did to the 2F to improve the performance was negligible and a waste of money. There were times I could not do the speed limit on the highway with a head wind. Off-Road did not notice the lack of power at all.

I now realize that if you treat it like and drive it like a tractor it will do what every you need it to do as it was designed.

When I finally got a diesel with the F250 I was surprised how a low dollar amounts of change you could feel in the seat the change. I made a poor man's cold air intake and felt the change. Put dual exhaust on it but should have passed on the glass packs. When I was doing a ship turbine job in Portland the injector pump started getting air locked so went to the IH dealer up there and asked for the biggest injector pump for the 7.3 IDI non turbo and put it on. Once I got it dialed in there was improvement. But smoked like a F4 jet on every grade after that.

I had a SBC that I planned to do a stroker kit for the torque gains but the HP gain would have been to much. Then I started looking real hard at do in a diesel swap.
I wanted to build a 283 corvette motor - not so much interested in HP vs more rpm's.

Back in the early 80's a friend pulled the heads off of a 350 sbc and had .050" cut off them. It was the 1st I've ever heard of such a thing. About 8 yrs ago we were doing a cheap rebuild of a sbc, and a friend was measuring the volume of the dished piston, head combustion chambers, head gasket thicknesses and such. It was a weak 350 at about 8.25:1. We did the math and figured .050" off the head would be around 9.25:1, which isn't insignificant.
I agree about turbo diesels. The better they breath, the more power and efficiency you get.
