I’m thinking of adding a supercharger to my ‘66 F100 with the 300 I6. I’m not looking to go super crazy in “boost.” Maybe 5PSI but I’d like it across the board. Do any of y’all know what would fit or work? I’m fine with piecing things together.

Also what would be a good carb to run with that?

centrifugal supercharger would be the ticket but would need blow thru carb. Same with turbo.

Efi would be much better but talking lots of $$ for supercharger and EFI. If $ not a issue go for it.

So, you got your carb issue ironed out, and on to the supercharger now?

you are prob looking at 5000 to do a proper Supercharger. Where as a cheap turbo for about 1/2 that.

Without any idea what your budget is it would be nearly impossible to help.

seems to be running fine now. Just spent some time messing with it. Still looking to move to something other than the stock single barrel but now it’s running perfect. So I’ve got some time to figure out exactly how I want to go about building the engine

I’d perfer to run a supercharger over turbo. I personally like how the the throttle input matches exactly what you want without the lag. And I’d prefer the low end.

Ive worked with turbos and I love them. But I love a super more.

Im not exactly worried about the money. Obviously I don’t want to pay more than I have to but I’m not so worried if it’s $5k or so.

Ive thought about EFI but I know carbs pretty well and honestly don’t know anything about the modern stuff. And EFIs tend to run expensive. I don’t know something about having a carb just sits a little better in my heart lol.

I will put in headstuds and will do the pistons and rods and possibly the crank.

And I’ll be running 100LL when do get everything set up. I know about lead coking (I’m an aircraft mech) but it’s really not an issue. Nice part is if I run it a bit rich it’s equivalent to 130 octane. So I won’t have to worry about detonation

i will start a thread on it when I begin the process. I was thinking 5PSI just because I didn’t want to have to change a ton in the engine but then again if I’m going to swap pistons might as well change everything else out since it’s all apart.

That was the other reason I wanted to supercharge the engine. So I’m keeping that 3oT and going to find a race tranny shop to find out how I should gear the transmission and swap out the gears for stronger internals. I love the gearing as it sits but I would like 2nd to be taller and 3rd to be more of an over drive. And having the added boost from a supercharger allows me to do that and still tow when I need too.

I mean im already in 3rd gear by 25-30 mph and then that runs me all the way to 85 (but I don’t drive it past 70). I have thought about the floor shift but something about 3oT I can’t give up. If there’s no way around it I’ll swap to a floor shift but I’m hoping not.

Thinking I’ll try to get a root or twin screw style because I’d rather have a positive displacement.


Something i forgot, ignition, what would be some good options?

dura Spark dist with a msd box maybe with boost control. But 5 psi so little prob will not need.

My ‘66 F100 Ranger has 3.25 gearing with factory 3 o T. OverDrive Plenty of TQ at all speeds with stock 352. Around 35 mph per 1000 rpm It does So well not going to change a thing.
