Willys are just pretty carbs, with colored bodys etc, and the new ones have a billet base plate.

Unless your building a show car, they are a rip of period...

Thats the undersatanding i got straight from Willys a year ago or so when i was going to buy one. they are just hand selected holley carbs...

i have a willy's and it is anything but a rip off. it is not pretty colored looks bone stock with a emphasis on looks. the base plate and metering block are custom not stock holley. as a test i ran a 650 holley and my willy's on test and tune night their was no comparison the willy's turned about 200 more rpm and better throttle response i will look later and see if their is any markings on it

for your test did you have

the same jets,
accelerator pumps
accelerator pump cams adj. the same also
same accel pump squirters

if not its not much of a test. one of those being diff will make 200rpm diff, so will about 5 lbs of air in the rr, and a looser car.

correct me if i'm wrong but you cant jet a carb flowing 500 cfm the same as you jet a carb flowing 650 it would be a little lean. same goes for squirters etc. you can not tune a bigger carb to the same specs as a smaller carb. yes both carbs were properly tuned to and jetted for the motor they were being ran on. was this a highly scientific reliable test no. did it prove to me that a willy's isn't a stock 4412 it didn't need to i own one all i need to do is pull the bowl off and look at the metering plate. i am happy with the carb as well as the dozens of other top cars in my area that run them. i just don't believe that a salesman for will's told you that they are for show just hand picked holley's that would be awful bad for business now wouldn't it. i bet he said the start with a hand picked 4412 and then change base plate and metering plate and tune to their specs. matt

So you think that changing the baseplate, and metering block is going to make a 500 a 650 cfm carb, even though the body is stock??

Willy told me it wouldnt and even named several places that were more in line with what I was looking for.

For example the carb shop. which actually bores, polishes the body etc. the REAL modified carbs wont pass a go no go gauge.

Glad you like your willys and it was worth extra money to you!!

It seems you have made up your mind....not that I care what carb you run. I also had a holley 650 at one time and a stock 4412. I bought the Willys and neither the 650 or stock carb will see my engine again. You can tell a difference in performance, but by looking at the carb it looks stock!!!

I also forgot to mention.....I believe that the willys carb has different stages. I just got mine back from Willys for the annual refresh. Mine is somewhere in the middle....for another "X" amount of money I could add another 15 horse. I chose not to upgrade!!!

if you would re-read my post you would see that the the referenced carbs are two different carbs a 650 and a willy's. some people actually have rules and tech my carb gets a go no-go gauge stuck in it everytime i show up at the track. if your track doesn't have a 500 cfm rule, isn't enforced, or you choose not to follow the rules then yes a willy's probably isn't for you. that still does not make it a "show carb" and a rip off for some one who wants in my opinion one of the best carbs available

I don't have a clue on any of the info you asked for but I have a thought on your problem. If you are in doubt that you got what you paid for, can you send it back? If you can I would just send it back and find a reputable dealer for a willy's. That would beat a $450.00 loss. If you can't send it back bolt it on and run it and see what happens. If you don't like it I would send it to KPLUGNUT for some fine tuning and chalk the loss up to experience. Been in your spot before and kept what I should have sent back to play it safe. Just a thought to keep your cash and sort out the facts. If you send it back and someone finds the #'s you need you can always reorder from the same place.
