Put the meter on it and took it to work this morning, drove great. Ran it up to about 5500rpm in 4th gear and it didn't skip a beat, so whatever it was the other day is intermittent, which sucks. I did notice it seems to blow fuel out of the scoop on decel after being in sustained boost...

Went past the point of no return, cut the hole in the hood. Actually the guy that owned the car for the last 40yrs before I bought it did it, he did a great job. I have about 300 miles so far on the setup. I had to abandon the vacuum advance idea, it seems it could not act quick enough with a...

Got the clutch straightened out. Somehow the clutch linkage was out of adjustment and it wasnt releasing it all the way. I dont know how long it will last, but its a tire burner.. Going to have to cut the hole in the hood now.

Well i def had the supercharger over filled with oil. Drained it to the correct level. Pulled the hood off and took it for a ride. After some playing with the carb got 14.4 a/f idle, 13.1 cruise, 11.4 wot. Total timing 36 out of boost, 25 in boost. Boost numbers around 6.5psi. Didnt get on...

I believe it was bone dry or darn close to it. Took about a half a quart to bring it up to the nut of the gear. Any idea where the oil level is supposed to set?

How much oil should I put in there? I checked B&M and they said to the sight hole, which this one doesn't have. I added to the center of the gear inside and figured it would be enough to idle it with.

It's alive. Learned a couple hard lessons. Apparently that extra hole that isn't used in the block when switching to a modern timing cover on a 64 273 goes into the water jacket... Found that out Saturday. Tore it all back down, installed a plug. Put it all together, holds coolant. Runs...

Doing the math the setup I have on the 273 shows 12psi, 7psi on a 340, and 5.7psi on a 360. I am going to start out with a pretty fat a/f, and around 24 degrees of total timing. Hopefully will be getting the radiator tomorrow and hoping to fire it up this weekend. If she comes apart, she...

Using that formula comes up with 12psi. Think a stock motor will hold it?

How big of a motor are you running? I want to type the numbers in the calculator to see what boost numbers it comes up with. Depending on the eff% for my setup it says anywhere from 12-24psi. Stock 273, 144cu/in blower, 3" upper, 6" lower. If you put the numbers in for a 340 and it comes...

If you are asking me how much boost, I haven't run it yet. According to the online calculator I should be ordering a bigger pulley before I fire it because its going to make too much boost for this motor to handle. If you type your setup into the calculator link does it come up with the boost...

What size motor and what size blower are you running?

Want to sell the bottom 6 rib pulley? Mine has a couple teeth knocked out of it. Whatever this thing does, its going to do. It is strictly a fun driver. Though I will def. take it to the track and see what she will do. Question for everybody running similar combo's, when you type your...

End of mounting flange to end of pulley is around 11 7/8"

Thanks, it was interesting painting the intake, timing cover, and waterpump to look like it hadnt been touched in 40yrs.

Getting closer. Had to change everything. Waiting on the radiator and a few other things.

This is the setup I was thinking about with the 273 w/roots blower. Did you put a check valve inline to the distributor so it did not get boost to it? I am just curious what the timing would do if the pod saw boost.

Finally started mocking this up. Boy the ports on this intake are huge. It is going to be very interesting to get them to seal up to the factory 273 heads. lol.

Well i am sticking with the manifolds and the 40yr old side pipes for now. I have a msd digital programmable ignition that was going on the f.a.s.t. Duster but it doesnt really need it, so it may make it on the barracuda so i can lock the dizzy out and build my own tables, i think i can...

Where did you get 4-5psi from? Everything i am reading with a 273 and a 144 50% overdriven is at least 7psi? Just curious and trying to learn.

Its a stock 2bl 273 w/ felpro gaskets. I assume somewhere around 8:1 but honestly never did the math. The cam is a summit hydraulic .454 lift. http://www.summitracing.com/parts/sum-k6900/overview/make/plymouth?ibanner=MobileSwitchNo Runs fine with 87.

Bought the setup jimjimjimmy had. He gave me a killer deal and is a great guy! Showed up in the mail today. Has a 6" lower pulley and a 3" upper pulley so is 50% overdriven. Based on the online calculators could be anywhere from 7-14psi based on the efficencys of both the engine and...

I think it is begging for a blower...

I know there are a few posts from years ago. Just curious if there are any "easy" ways to put a small roots blower on a smallblock. After buying pretty much everything to throw a turbo on my barracuda i decided it would look much cooler with a small roots blower. Not looking for maximum hp...

I think the procharger will make up for the larger plenum.

Well according to the company I bought it from, in the package it should have had 3 flanges, 2 for the v-bands, and 1 that has an interference fit in the wastegate to seal the valve. I got all the other components I should have had, except the one flange that acts as a seal. Of course, they...

This one is the same way, but the flange in no way seals against the valve.

I'm thinking there should be a pressed in sealing ring or something? Don't know. The b.o.v. and turbo look pretty good. Got the manifolds, piping, flanges, carb, etc. Need some time to get this thing going.

I have an email into them to see what they are going to do about it.

Here's a pic of what I am talking about.
