Probably wouldn't need it with the $20 approved fuel ;-)

The turbo cars had a side draft Rochester. Other models had a 4GC.

The suspension is similar to a Chevelle, but the coils are on the trailing arms, like a Fox body.

I doubt anything modern would bolt it to replace the Jet-a-Way (Slim Jim)
Probably could use a later Land Rover block that might have the B.O.P. pattern.

You're (of course) right about the carb. Same as turbo Corvair, wasn't it?
As far as the alcohol injection, didn't they inject it into the turbo to cool it?!?

Looking at the pics, I guess they inject it into the carb..

Actually, the Corvair used a Carter, but similar style.

Rather than lowering the compression, Olds decided to inject the fluid to cool the combustion..
I'd suggest using an MSD Boost Master timing retard control with this one ;-)

https://forums.aaca.org/topic/108020...draft-rochest/. To complicated for 1963. I do recall at least one that came in the station I worked at. Plagued with problems. Engine and trans. The Slim Jim was poor in everything GM put it in.

Well, seeing as it's 3* outside and the wind is blowing like a banshee AND boredom is setting in,
how about a 63 Chevy II 4cyl 153/90/90 for W/S or W/SA at 2330?
Same basic engine as my 230s minus 2 cylinders.
I guess the problem would be finding one but it would be fun with a stick and probably pretty quick with a metric!

No, kinda like the "Iron Dukes" grandfather.

ok,
Iron Duke late 1960`s? I recall a 68 or 69 Nova w/4 banger, and a guy called it an Iron Duke.

The Iron Duke popped up in the late 70s and lasted through the 80s. They had some similarities to the Chevy II engine but I don't think there was much in the way of parts interchange.
The Chevy II 4s were used by Mercury Marine for a very long time. I know they survived into the 1990s and maybe later.

How about a 1982 Camaro with a 151ci Iron Duke 90HP / 120 NHRA HP

U/S or U/SA at 2570#

OR

SS/PA or SS/P at 120 NHRA HP and 2210# min weight...

Too bad that the Quad-4 never came in a rear wheel application, I think?????

That was a very trick engine…..

Also in Mail Jeeps. That's the source of the Chevy pattern 904's ,later used in Comp.

The story is they would have been real dogs, fully loaded, with a PG.

Re: Fly Weights
 
Friend of mine's father bought three old mail jeeps for his pest control business. I drove one at Southland Dragway in Houma around 1974. If I remember it ran 24 seconds with the sliding door opening on the leave.

Re: Fly Weights
 
The Iron duke was used in various cars when I worked as a line mechanic in the mid to late 70’s. It had both intake and exhaust ports on one side of the head around 1976 and was changed the following year to intake on one side and exhaust on the other side. Many engines from all manufacturers were used in industrial applications long after they were discontinued in vehicles. The iron duke was one used a lot to power generators as well as marine engines. It had a very long life in various configurations!

Ah ! Billy and I have talked about that one.
Nobody has had to use one with a 302 yet.. It might come to that, eventually.
Take a look down through one, with the throttle plates and the top flapper open, and let us know what you see ;-)

How about one of the 68-74 Opels in the Guide? A 1971 Opel 2-dr sedan or wagon with the 115/75 2bbl L-4 has a minimum weight with driver in T of 1880lbs. It can go as low as 1790lbs in R.

I thought I saw a Multi color Maverick testing one at Wildhorse. Looked like some bugs to be worked out,but I was impressed. Maybe just seeing things. I think it might really upset Capt Jack

I have already posted this one earlier:

65 Chevy II 100 2-dr sedan w/ 283-220, 229 rating H/S 2804 lbs w/driver, 223 rating H/SA 2735 lbs w/driver, 2779 shipping wt.

I've wanted to see the AMA publications on the '64-'67 Chevy II's; the variety of shipping weights from NHRA doesn't make sense to me.

Has anyone tried the '82 Mustang GT 302/2bbl - stick combo ?

Or is it factored too high ?

Would be 2,682 lbs with driver in P/S

There were a couple in the NW with automatics that ran well, until the transmission deal was clamped down on.
Definitely NOT factored too high.
I've heard of a couple being built, but never saw them out there.
Those cars did a disappearing act , even around here. Believe me ..Been looking for 5 years.
One of the few carb-ed cars I'd build in this day and age.
I'd run R/Stock , for sentimental reasons..3000 lbs , not too heavy for a stick car.

I know everyone wants 1.20 under handed to them, but this is an easy 1.20 under car with a little effort.

All 61 to 63 F85's automatics came with a Roto 5 transmission, a smaller version of the transmission used in full sized Olds and some Pontiacs. The only PG's in those series of cars was in the Tempest, used a Corvair powerglide. Only the Tempest was IRS.

I have a couple of 78-82 FOX body clutch pedal assemblies (pre quadrant, factory style cable is adjustable at the clutch fork end.) If you are interested.

Why?!? 135 HP with a 1bbl carb and an integral intake. 302 @157 HP has big 2bbl carb, big "marine" cam and aluminum intake AND 100 extra cubes. Give me the 302 and the extra 22 HP.
