“I do not care about money.” - welcome to the forum, it will be fun to watch.
speaking as an ex-racer. I prefer EFI over Carbs every day.

I am slow..
Had to move South.. Just started on the Taj Garage.. Going to take a while longer, BUT I have welded the 2 BBL manifold boss to the aluminum base plate and did a big radius on the inside edge. I will be using the Holley 2 BBL Sniper EFI set up for the main install, it is 350 CFM.

Sorry, got cut short..
That is a Melissa M1 cam I just got back from Industrial Hard Coat in Denver NC. They cater to the small guys. The cams coatings was 250.00 and the rocker shafts were 125.00, 1 week turn around and they are the DLC originators and do the coating at 150 degrees instead of 450 like everyone else so no damage to parts. I have known them for a long time back to when they were in the DC area and now they coat for all the big teams but it was nice to call and get a good price and fast turn around theses days.

I made up a simple throttle linkage that integrates with the stock rod that pulls down on the stock throttle body arm, very smooth action

Well doo doo happens, I'm waiting on my final building inspection so I 'm not suppose to be working on anything yet but I got a hammer and Visegrips so..
![]() ![]() I got the carb mounted and have more room than I thought when I was doing the mock up and measurements. Now I'm waiting on the last part, the fuel pressure gauge is no here until Tuesday?

Curious how you plugged the fuel injector ports on the runners?

I used a large head screw from McMaster-Carr that fit and sealed it in with some Honda Bond so I can revert back If I do the Ian Carr Fuel injection in the future.

Got the car running.. Much smoother and more torque from the butt dyno, so this would show the need for the fuel distributor rebuild on the CIS because I could not get the FD to set back to the same place twice at idle. The carb is easy to adjust and needs a lower power valve size and a smaller jet in the accelerator pump to make the gas shot last longer, having an AFR gauge makes tuning easy.
All said these are easy adjustments SO FAR, and I expected some changes needed going down to 183 CID VS a 350 small block Chevy. I will post a video on my YouTube site when the weather cools off here to show how nice it starts, the pump the peddle once and bang zoom is a really nice change

nice work actually following thru!
You remind me of a guy that I used to know from some motorcycle forums years back that went by the handle "hackasaw". Just to make sure, that ain't you is it?

Hmmmm. With that moniker, I visualize you as a deadly old fart. Now, 'Old CH4' would conjure up notions of a regular stinky old fart. Perhaps some chemists out there will chime in, as my chemistry is a bit rusty now at 40 years old.............Just couldn't resist!

Well your very smart and learned something in school..You can't believe the trouble I get into, I spent lots of time working in China and I would catch the engineers with "Pull my finger" every day, they never learned. And I would fart in the slow elevator going up 12 floors most of the time, they called it " American Kung Fu" . Must have been the food.

Well, it surely sounds like your moniker is well deserved. Old H2S it is, then.........Good man for knocking them out in the elevator!!!! PS- When I was a wee lad, it took me 2 or 3 times of pulling my dad's finger before I learned his trick, but I continued to go along! Some things just never get old...........for children of all ages!!

How is this running now?
Has anyone used a Holley Sniper EFI kit in a similar manner?

Wasn't someone talking about making these manifolds? I can't find the thread now.
Getting tired of hard starts and high idle on my CIS-based car and I'm too poor and lazy to go for the ITB option. I like the idea of throwing a Holley Sniper on there.

Yeah, that's me..slow project so far. All my engineers are working on the moon shot and getting their butt kicked by Elon so getting them to work on down time is? They come down here to fish and hang out. Rarly Late has some information ( M&K Exhaust)
The Holley 4412 runs great and I just sent my tuning set up to CCS Carburetor's in Virginia Beach for his library. I might do a Sniper system when I get bored but right now it is too much fun and has more low end grunt than any other set up. I just back from the East Coast Porsche get together at Cecil County Drag way in Maryland. ICARP came from the west coast with the new Kermit and I am not aloud to say what the output was. You will have to bug Ian for that. We had fun rat racing for hours through Maryland, Delaware and NJ. ![]() Trouble brewing..
