Technical 1957 Chevy HEI & wiper motor options?

Hey folks.

I have a question.

On my '57 wagon I have a newer 350 w/ 700r, and the vacuum wiper motor. If I get a stock 55-57 electric wiper motor, will it fit ok with the HEI dizzy? I hate to spend the $$ getting an og motor only to have it not fit.

 

Wow. Not one reply?

I am going to have to talk to the management around here.....

Looks like a good alternative and could provide you the room without any interference.
A large standard bodied OEM HEI will always cause clearance problems, a smaller diameter HEI is different as it's the same size as OEM distributor.

 

I've done it with my old '55.....worked fine

 

The electric wipers might interfere with the operation of the HEI magnetics. If so there is a polarity fix out there , let me know...

 

Does the HEI interfere with the vacuum motor ? If not, why change it ?

 

what he said

 

Did it several times in a shop I worked at. No problems.

 

Thanks guys.

I found a rebuilt stock electric motor in craigslist for $100, but I missed out on it. I am trying to get the stock vac motor to work, new gaskets etc, but it still isn't working right. I need to tinker with it some more. I figured if I could grab a good elec motor for 100, rather than spend 200+ on a rebuilt one, or the expensive raingear kit, I'd be good with that.

 

Just a crazy question about GM vacuum wipers then. My 55 Olds motor has a dual acting fuel pump that helps run the wipers. From what I remember about all the tri-5 chevys I had many decades ago, chevy never did that?

Silly question, but I was just wondering why some car brands had different setups

.

 

I think chevy did that with some of the inline 6 engines?

 

How a Tri 5 thread got past me for 3 days, I can't understand. Let alone one with 1957 Chevy in the title.. Engine out of mine at the moment, here's a comparison. Nice wagon BTW!

 

awesome pics!

what is the dimension comparison say from the centerline of the motor to the bottom of each when mounted?

 

Hope it helps ..... That's from top down . 1" difference give or take

 

My 57 Fuel injected BelAir had a factory auxillary electric trico vacuum pump that was triggered by low vacuum and it worked very well but they are kinda scarce and pricey as well.

 

FWIW I would try NEWPORT Engineering for an electric wiper. I've had one in my Safari for 10 years with zero problems after smoking a NOS Chevy motor(same as Pontiac)I bought at a swap meet.Bolted right in in less than a half hour.Biggest problem was the switch:the set screw was in the wrong place for the Pontiac dash.Finally got it installed and contacted New Port about it and I think they changed it on their subsequent models.
As I understand it they are the same as the early Corvette and they usually want telephone numbers for a price for that stuff.

 

Newport is the way to go, used a bunch of them. Never had a problem.

 

Thanks for the pics!

I am just not ready to spend that much $$$ for the Newport set-up.

 

The clearance Clarence will be with the firewall not the wiper motor. Depending where ur engine and body ended up on that frame sometimes you need to massage the firewall. I just run msd plug and play distributors. No fitment issues. And I swapped all my tri fives to electric. My .02
