A while back i was told that it couldnt be done. I already had the intake mounted and ready to go but i has been a long times since i have even messed with this car. I broke down Sat working woth oldsrocket and this is what she ends up looking like Its a 263 straight eight in a 50 special with a pair of 94's The car is still 6 volt im running an electric SW fuel pump that feeds into a holly fuel reg and then a old block splitting it.. Yeah i know the fuel line is huge the motor is nasty right now and i need to fix that wire on the generator. Wiring is next then pipes ...
All the '41-'42 compound carb setups around here used 94 or 97 with no problems. Damper ***'y was always removed and solid linkage built. 302
I'm a little confused about the "motor mount issue" that the '41 dual exhaust set up supposedly creates. It doesn't appear to be an issue for Road devil, but it looks like that same exhaust set up wouldn't clear Fat***buicks motor mount. Road devil, do you forsee any problems runing your pipes?
I dont really see too much of a problem its going to bet a touch tricky but i have room to play with the exhaust is going to curve till the pipes about touch then run down together thru the x frame and im keeping it too pipes close together all the way out the back. the ends of the manifold are farther away then you think being such a long engine. THe motor mount heal is a whole other story that want as easy... fat*** the port on the front of your intake is for cooling right why did you never hook it up? This is from the front the little odd ball deal under my rear carb you can sync the carb with the big round knob it was stock in the 41
Actually that port on Fat***'s (Edmunds?) manifold is for carburetor heat, not cooling. Running with it disconnected is no different than running a Flathead with the heat risers blocked--no affect once the engine is warmed up.
You don't have to tell the whole story, but I'm wondering if it is stock or if you had to modify it for some reason. I p***ed on the old dual manifolds set up because I thought the mounts would get in the way. Does anyone know if the motor mounts are the same on the '50 and my '52? Yours just look lower to me in that photo.
RD, That thingie under your rear carb is not for "syncing your carb" ... it's an air damper which must open before the carb will even function ... 302
My mount looks lower do to i had to cut it and lower it to make the manifold work. I put a unisnyc on the carbs and got them dialed in then fine tuned it with the "air damper"
A friend of mine has this in his 41 Buick. It was allegedly worked on by Mickey Thompson back in the early fifties and this is how they figured out how to get round clearance issues! The car was never finished and left in storage from around 1953-4 till he bought it a few years back. It's still a work in progress but it'll get done one day. And in case you're wondering it sounds incredible!
Chub, someone pm'ed me about how I did mine a couple of years back and I couldn't rememeber until I saw these pictures. On the O.E.M. intake you have to turn the block mounted motor mount upside down. Then fab a plate to mount your frame side motor mount to. The frame side motor mount I believe I cut in half and fabricated a small portion to lower it on the frame. Fat***ssss's intake has a single center dump exhaust port I believe. I had put mine on a 53 buick. TP
Thanks TP, I'm not looking to do mine any time real soon, just gathering info for when the day comes. Wrong-Un, that is amazing! I would love to see it in person, do you have any more pics?
did one of these last year right before round up (like minutes before) and yes, the exhaust was hellish. buy yourself about 7 2 1/4 mandrel bends from imco and you will be alright, but be ready to do some cussing. getting it through the frame is a sum*****. aaand outlaw deleted the damn pics, so all I can tell you is you have to enlarge the holes in the crossmember right next to the trans and stagger your muffs. I ran my exhaust out of a hole in the frame before the rear tires. sounded killer.
"RD, That thingie under your rear carb is not for "syncing your carb" ... it's an air damper which must open before the carb will even function ... "!!! Yes! It is a kind of air valve secondary, and the eccentric knob is actually a weight that holds the shutter shut until it is PULLED open by airflow! I really don't think you want to leave that thing in there. It may actually be preventing all use of the carb back there... You really want both carbs full time on this thing. Having the full time carb way down at one end was one of the reasons the stock dual setups had an evil reputation.
Bruce and 302 are right , that flaper is for the stock rear carb which had no accelerator pump and was used as an idle circut , when the intake ****ed the flapper open it got more fuel , but when you over tighten the carb bolts , the aluminum body crushes and the flaper will drag , which is why you can "dial " it now, when woking well , it will flap and the weight will close it , you need to remove it if you are using 94 or 97 carbs , and use strait linkage so the carbs open together . Also check that the heater flaps in the exh. manifolds , if they get stuc closed , like they do when they sit for a long time the manifolds will keep heating and will crack , best to just wire them open.
I was wondering about the exhaust port configuration on these motors a while back. The set-up looks a lot like some V8 set-ups (i.e. SBCs). Is the spacing close enough to a common V8 pattern to use a set of regular aftermarket headers on one of these beasts? That way you might have halfway decent flanges, and you might be able to save a buck or two...
TP, I IM'd you last week and said I was going to get you pictures of the motor mount on the '53 but I never did, sorry. I actually have Fat***'s buick but its no longer ' Fat***' Buick. Oh, it still has a fat*** but the name has changed partly out of respect to the old owner and partly due to the fact that the car is starting to evolve again. Its now called the Suicide Sedan due to the rear doors being suicided recently. I have a set of the 41-42 exhaust manifolds ready to bolt on. I was looking for more info about the motor mount if possible. If you need me to post more pics, I can (Sure I will). Fryguy
