Need help with '56 camshaft

[Duke W.]

As part of my ongoing SB camshaft research I've enlisted the support of a well known supplier to the racing industry with an excellent reputation going back over 40 years. We are now looking for a 1956 base engine camshaft, which would include the 210 HP single four barrel engine and 225 HP dual four barrel engine.

I pretty sure this is a hydraulic lifter camshaft and the part number is 3711354 casting number "355".

If someone has a new or used camshaft meeting the above description, would you be willing to loan it in order to have it analysed with a Cam Pro Plus camshaft analysing system? The Cam Pro Plus creates a complete data file of lift, velocity, acceleration, jerk, and base circle runnout every crankshaft degree (one half camshaft degree) - essentially a complete reverse engineering of the cam to understand its design.

If you can help out, e-mail me and I'll put you in touch with above individual to arrange shipping.

I don't have one of those and it's going to be a bit tough to find one. The GM #3711354 camshaft was discontinued in July, 1975, so it's been "dead" for almost 30 years. However, you never know, one might "pop up" on eBay.

Re: Need help with '56 camshaft

I'm hoping that someone has one that they removed from and original engine and saved. A new cam would be best, but a used one would be okay if not severely worn.

Another identifying feature of this cam is that is has a groove on the rear journal as do all '55-'56 SB cams.

BTW, the numbers from the Cam Pro Plus on my Duntov cam showed virtually no wear. It's still serviceable, but I already replaced it with a LT-1 cam.

Rare camshaft supplier...

Glazier's Mustang Barn gets rare old cam designs from a manufacturer who has never been stumped by them. I'd be willing to bet if they didn't have the 55-56 cam on hand, they could make one up from their records. Have GMB give them a call!
