Early F.I. Intake Manifold Gaskets

Re: Early F.I. Intake Manifold Gaskets

there is no need for the FI intake gaskets to have a crossover blockoff because the FI base plate that bolts to the block has no heat riser passage to block off..

Yup, agree. Besides, the GM FI side gaskets are no different than the conventional gasket that GM used for carbureted engines.

Hey Guys;

What is it that I have stuck in my photographic mind about these gaskets with the "blued" metal plates with an oval hole in them that we always used to call "fuelie gaskets"? I completely agree there should be no need for these plates, and that's one reason I am asking about them. Guess I'll try to call up some of my old hot rod buddies and pose the question to them. If they tell me I'm crazy, then I guess I'll have to go see a shrink! I used to keep a bunch of these gasket sets around for any manifold change, and I shopped at Don Hutson Chevrolet a lot. That place was torn down and replaced by a Marina (what a waist).

Well, got to go retrieve the wife at the airport. See ya.

later model carb engine used this type of intake gasket to get the correct amount of heat to the hot air chokes that used a SS tube in the intake heat riser passage crossover for a heat source

I vaguely remember a GM gasket that may be similar to what you describe but I seem to remember that from around 1970 though?? I don't think they were actually for performance engines though. In fact, I don't even know for sure that they were GM. I dunno.

There may have been some other "over the counter" special intake gasket sets available in the late 50's/early 60's but I don't have any record of any such gasket sets.

I used to use the 3772684 sets but by the early 70's, the end seals were dried out and every one split and leaked within a few days of installation. There was no baffle or block off for the heat crossover.

Add On; I see Clem just posted the same thing on the gaskets with the baffle so I guess that's correct.

Re: Early F.I. Intake Manifold Gaskets

I believe that Chev supplied block off plates in a envelope with some straight axle cars. Dave Bartish wrote a article on this in a early Restorer. I own the car GM tested them on. Engineering #6911, 56#1009.
Regards

Bob Pinkney owns a set of original 57 metal block off plates still in the original envelope.

Re: Early F.I. Intake Manifold Gaskets

Gary,Thanx very much for the info. I bought a Sony cybershot one from Office Max. A cheap one that is still in the box as a 15 yr old girl is supposed to show me how to use it. My one day a week wife has a daughter who is supposed to come to the house and show me how to put pics on the internet and then boy are you guys gonna regret it. Especially MH. Thanx for the help. Now to re-read the directions on how to print just your reply and not the whole post. God I have wasted a lot of ink. John

Re: Early F.I. Intake Manifold Gaskets

Gentlemen;

I have an apology to make. My thread is mis-titled. I have found the info on the intake manifold gaskets, altough I don't have a p/no. as yet. They were indeed GM, but not for Corvette Fuelies or any passenger car engines. Rather, are you sitting down, they are for medium duty truck V8 engines from (as I thought) late 50's early 60's. Now does that ring anyone's bell?

Back in the day, we were always looking for any advantage we could find for our hot rod dragging V8 engines and we often went through the Chevy Dealer's parts bins. We used a number of truck interchangeable parts, including heads and clutches; their driven discs had more metallic particles in the lining, the truck eleven inch diaphragm pressure plate and flywheels (my last one went a whole season w/o failure) and, yes, gaskets. Most of the draggers back then were using heavy duty "white" coil spring clutches that you needed two feet to push in and you were always bending linkage, etc. I found the truck 11" after wrecking a transmission and watching my 57 dash board torque when I pushed the clutch, as well as snapping off the pedal bracket under the dash. With that diaphragm clutch, I could power shift till the cows came home using just my toe on the clutch. The heads were a failure though as they had nice combustion chambers (less shouding around the valves), but they used a larger diameter valve spring with a different open/close rate which did not work well with the Duntov Cam. You gave up a point in compression ratio and the engine strained to make 6500 rpm.

So, I apologize for my memory confusion on this subject, but I am disappointed that I couldn't ring anyone elses bell. Surely I wasn't the only one to snoop the parts bins back then.

i can remember the bigger chevy trucks using buick "nail head" V-8 engines back in the 50s/60s

Re: Early F.I. Intake Manifold Gaskets

Clem;

I recall running across some of those back in the early 80's when I was helping my brother-in-law look for older used trucks for export to South America. Guess they used them (some Buicks) until they got the 348's up and running for some duty cycle gas engine applications. I recall the engines were painted their blue/green, just like the passenger engines and I was surprised the first time I saw one. I thought it may have been a conversion until I looked at a bunch more.

You never knew what you'd find in trucks - lots of combinations, specially with the diesels.

Thanks for your kindness and understanding on this subject. At least you know it is not wise to "never say never" about parts combinations in the automotive business.

at that time chevy only had 283 and the buicks were 322 cu in i believe

I think you "nailed" that one - pun intended.

The Buick "nailhead" was a neat engine once you got past the small ports and valves - I put one in my '53 back in 1959, and started with a 3x2 intake and a Harman-Collins roller cam. Later pulled the 3x2 setup and swapped it for a 6-71 blower with two WCFB's, and it REALLY came alive; ran low 12's at 120 with a LaSalle 3-speed and 4.11 axle - was my "Woodward" car.

[Stuart F.]

Re: Early F.I. Intake Manifold Gaskets

John;

WOW! What a combination. Guess it was the blower that really brought them to life, what with their small valves. We had a fellow that ran Union Grove with a rail job that used a reversed system, i.e. blew in through the exhaust ports, exhausted through the intake ports in order to over come the long and small exhaust porting (nothing better than a 6-71 to overcome that).

Been a long time since I heard of a Harmon - Collins Camshaft. My first thought went to "Harmon-Carden" stereos, Ha!

With your La Salle 3-speed, did you use the original floor shift? If so, wasn't that a pretty long throw? We once used a side shift model that we made our own floor shift conversion. Worked great. That was in an old 53 Pontiac that we put an Olds V8 in.

Stu -

Used the original central shift lever, shortened so about 8" of it came up through the floor - worked fine.

There was no better looking power plant than a nail head Buick with a set of polished finned valve covers and a set of multiple carbs - *itchin!
