did they ever make a solid webbing 403 and what applications did they put them in? thanks

 

Only in Mondello's dreams.

Kind of makes one wonder how, in the 34 years since they were allegedly cast, there has not been one photo taken of a SMW 403.

 

There are more photos of Nessie , Bigfoot , and UFO's than the SMW 403

 

The only solid main web 403 is a .015" overbored early 400 lol.

 

Good one, Joe!

 

I have a buddy whos build a few 403's. The ones that came in sedans with towing packages and a select few asembly locations

 

And yet, still no photos or other hard proof...

 

Of coarse, thus the legend lives on, lol,

 

Rumour is they exist... but nobody's ever seen one.

Chris Witt in MI has a standing high-dollar reward offered to anyone who can produce proof of one. He's still sitting on his money.

If I had to guess which cars might have gotten one, it would be 1977-78 Toronado, maybe 77-78 wagon, maybe 1979 TransAM.

But people have yanked the original 403s out of all those cars and torn them down, and still nobody's ever seen one.

Maybe that .015 over E-block 400 is where the SMW 403 myth came from.

 

I'm about to tear into my 79 ta. I have beat the motor pretty hard. (1 hr, rush hour, with a busted harmonic balancer) and the motor held together. If it is solid, I will definitely let chris know. I doubt it thou.....

 

Thanks for the reminder... I'd forgotten that I bought a 403 out of a Trans Am in 2009 that's still sitting in my garage.

Now I'm curious...but I'm not holding out any hope...

Rockettruck...

 

I am starting to think there are certain things that should be put at the top of the first page on this board. A few examples would be:

(1.) There is no such thing as solid web mains in a 403
(2.) There is no difference in headers for a Cutlass Supreme
(3) Which motor mounts to use when converting a 350 to a 455
(4.) If you are putting a Chevy engine in an Olds, you will not get the welcome mat rolled out by many people.
