Breathing new life into the 318 in the Scamp!

The exhaust is Hooker 1-5/8" Super Comps to 2.5" straight out the back (no X or H) with Flowmaster 40's. Real basic setup. This build has been the art of "if I can get it free or cheap, or trade for it, and it can reasonably work, it's good enough", even though it's not 100% ideal, but it's come together pretty well. Like I said, the only part that may not be workable is the cam, but I'll give it a try before swapping.

I'm also sold on the Demon. I can find bad things written about any carb or product, but I'm impressed with what I've seen. I'll get the smallest one (I think it was 625) and give it a shot.

I think we're both going to hurt some feelings of guys getting beat by grocery getters.

That's my approach! haha... The exhaust on this car was salvaged from the same setup you are running, only from my '68 Charger that is going to get bigger tubes down the line. It was all in good shape, but needed shortened, so I used it under this car. hahaha...

This is the 625 Street Demon. I think it's a little overzealous for the 318, but those primaries and tunable secondary air door will keep it doing the right thing on vacuum.

And yes, this car literally gets our groceries. No joke. Fetched our christmas tree. Love it or leave it!



I'm glad that I went through the heater. It was cold!

Hey Dave how's it going? Not sure if you remember me from Moparchat a few years back...

Anyway I have a pair of exhaust manifolds that might be of use to you, one is a 2-1/8" outlet Magnum manifold (pass. side) and the other is an original '68-'70 340 A-body piece (driver side). Only reason I didn't use them for my 360 is the 340 manifold has a crack that was brazed but in the process of grinding the brazing to make clearance on the cylinder head I broke through to the crack and didn't have time to fix it so I went with headers.

BTW you would get a big bump in torque and no loss of economy with a small fast-ramp cam like the Voodoo 256/262 or Comp XE, or pretty much anything besides the stock 318 cam that thing is *tiny* lol

It's been a while! I still visit there (TrashedCharger) and have been since 2002, but it's slow? It's been a while since I've been active on a car forum, oddly enough.

I'll take the manifolds off of your hands. I'm not afraid of fixing parts and eventually, I'll use them on something. I have a matching left for the magnum and the 340, even if it's damaged, I can fix at work. Don't chuck them for boat anchors. I may have some junk for your Duster. Josh, Jerry and I still have tons of A body stuff.

Tell your pops I said hi and check your PM. We should meet up soon, play some pinball and BBQ at my place with some other car people.


I'll post the prognosis of the valve work here, after I decide what to do with the heads. The seats look good on the heads, but these exhaust valves, while I think they will lap ok, I'd like to see a better seat on them that isn't so spread and pitted.



I think at the very least, I'm going to have the heads tanked. I don't want to try and get all of the carbon out of the runners with a media blaster. I think that's a few bucks well spent. I also have a fresh set of open chamber heads with valves in them that look nice. I may rob them. We'll see tomorrow, when it's not so late.
