Whew!!! My first gear ratio is similar to M20 2.50 and 3.91. (Mine is M22Z 2.99 and 3.42)

Thanks for accepting another package, I need to have a set of gauges delivered too. :-)

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!!!!!

Depends if you are talking Pure stock or modified... the record for pure stock is 12.38 ET, modified is unlimited.

Rallye 350’s are cool, especially the Sports Coupe’s!!!

Ryan W31

So is there any way to tell that the car is a legit Rallye 350?

- - dash dash special order Sebring yellow paint would be a good first step.
As far as I have read no W31 Rallye 350’s were built but W27’s were built.

Sam’s F85 is getting some barn find ink in Bone Stock and Modified Muscle Cars.

PS: Talked to a few shops this week to see about starting the sheet metal replacements/repairs.

Found an XT wheel for sale here on sYc so now we have 2....

Anybody got more singles?
