Carburetor Wedge Plate

no, not really. this plate discussion had me really out there. i thought i may have to go home, jerk the plate off and monkey with my floats although it runs great like it is. the 61 was a cool boat but the side drafts and y block ford was a bear to find stuff for in the pre-internet days. the bb chevy is pretty mainstream

You want to keep that pcv going, it ventilates the crankcase, keeping moisture and fuel fumes out so the don't contaminate the oil. A wedge plate most likely will cause some clearance issues with the cowling, something to consider.
I hope I didn't step on too many toes out there, but there are some issues that needed to come out. When I read a post about someone who put a new carburator on their engine and it won't perform or stumbles the first thing I think of is: whats your setup and have you dialed it in for your setup. Jetting is most likely correct, but when you tilt a carburator 15 degrees or so everything inside changes. Running a wedge plate is any easy and practicle solution, and maybe someday I might even consider buying one. Set you floats level (not slightly up or slightly down) and you should be good to go. There should be plenty of fuel in the bowls so that when the bow comes up under acceleration it won't stumble. Pick what works for you, there is no correct answer to this situation. As I stated earlier, given the choice, I'd rather have fuel injection! Cheers

Drill size 7/16, and the wedge platea were on chrysler engines.

Just installed the NEW carb from Michigan Motorz (tell them JB sent you!). Thought you all might like to know the results I got with the new carb and new wedge plate. Made no adjustments to the carb, except for setting the initial air supplies and idle. The first test was with the NEW CARB ONLY, NO WEDGE PLATE, followed by a second test with the NEW CARB AND THE WEDGE PLATE. Here's the basic, non-technical results:

1. NO WEDGE: Max RPMS = 4200; Max MPH = 38

2. WITH WEDGE: Max RPS = 4300; Max MPH = 38
****Had no issues with height restraints.

Not much difference in rpms or top speed. HOWEVER, I must say the holeshot was noticably improved with the wedge! Though top-end showed no difference to speak of, GETTING THERE DID! So, in short, I'm keeping the $45 investment from Glen-L.

Again, the wedge plate made a satisfactory improvement for MY BOAT, but it may not for yours. Should you decide to buy from Glen-L, be advised there are no instructions supplied with the 12 degree wedge plate and bag of bolts/nuts. I had to call them to talk to "BOB", the maker of this wedge, for clear instructions. It doesn't install like you would think. For instance, Bob instructed me to install the two longer studs in the manifold, then "bend" them to match the angle of the wedge plate. I was a bit hesitant to install anything that required my bending the bolts...but he insisted, and he was right. Gotta match the angle to get a good seal.

Well, enough discussing the wedge plate. The lake's callin'.............
