Thanks for the vote of confidence!!! There are so many W-Machines at Sam’s we are going to get a Convertible going first.

I would like to know what the difference is in a W-31 and a regular 1970 olds 350?

Balancer, and alum intake. I would think cam, but what else?

Now you are speaking my language!!!

Many subtle differences.

Special clutch (same as an L88)

W31 only specific items below:

Balancer
KA special water pump pulley
Flat top pistons
#6 heads (the W31 #6 heads have with 2.007 intake 1.625 ex)
Camshaft
Valve springs (also for W30)
Intake
Carb
Ignition has special calibration
Breather OAI

This is by memory.... I must have missed a few differences.

Thanks Ryan.

I've always heard of the W31 and a friend of mine built a W31 back in our High School days (early 80's). Car ran high 12's. It was a '70. We (group of car "kids" at the time) thought it should have ran better, like low 12's maybe even 11's. We always thought the Mallory Uni-lite ignition was crap.

Just increasing my knowledge base. Had an idea for a W31 "inspired" Rallye 350? I "heard/read" that unless you have a build sheet, original bill-of-sale, there is no way to tell if the Rallye 350 is a real car or a made up one? Talking to a buddy last night, he says I should do a Rallye 455!!!!!

Don't know how I missed this thread. Looks like it has been around since Feb.

Hey Ryan, how about some updates?

**Ryan1969Chevelle** · #7 08-20-2019, 08:56 PM

Pete: Thanks, I let Sam know so he can buy them. Nice memorabilia !!!

Lynn: This one stalled big time!!! I haven’t been nearly as available as I thought I would be and Sam bought a survivor 1969 Cutlass S W31 4 Speed and he has been working through the bugs to get it back on the road (sat since 1988)

What is the status of this project?

**Ryan1969Chevelle** · #9 04-11-2021, 12:50 AM

A friend of ours owns it now and is restoring it.

It will be such a killer car when completed!!!
