Name that dipstick

[Troy P.]

I have a NOS engine oil dipstick and I'd like help in identifying what engine and year(s) it goes with.

It is a one piece flat ribbon type. The overall length from end of finger loop to pointed end is 19 1/4". The finger loop end is 2 1/2" from the washer. The A dimension is 17 9/16" and the B is 18 7/16". The "Add" and "Full" are debossed.

It has a hand written tag on it that says "L 55-56" and the part number 3722960. I figure you can't trust any of that since it is handwritten by a previous owner.

Anyone know what this fits?

GM #3722960 is singularly applicable to 1956 Corvettes, 1st design, although it might also have some MD/HD truck applications.

The "A" dimension of the 3722960 is 17-37/64" and the "B" dimension is 18-27/64". These are very close to the dimensions you provided, so I feel pretty confident that what you have is correctly labeled as far as the part number is concerned.

Re: Name that dipstick

Thanks, Joe. You always come through with the good info.

Gary, someday I'll research how to post photos. You'd think I'd know by now.

Troy,
Is there a letter stamped on the upper part of the dipstick?

Troy,

According to my 1956 Chev. Parts Catalog (who I sold several years ago) GM # 3728130 is listed for the 1956 Corvette with the following description: 19 9/32" long under washer. The were no "A" & "B" dimensions given. This length is very close to your 19 1/4" measurement, only a 1/32" difference.

GM # 3728130 was replaced with GM # 3722960 in October 1956. GM # 3722960 is described as follows: 19 13/32" long under the washer.
A = 17 37/64", B = 18 27/64". The 19 13/32" is 5/32" (0.156") longer then your dip stick.

I would say your dipstick is GM # 3728130 for a 1956 Corvette. I guess that it is possible that very late 1955 Corvettes also used this dipstick.

The 1955 dipstick is GM # 3717868 (20 1/4" under washer to bottom), A = 17 13/16, B = 19 3/64".

Wow, there is some real dip stick expertise out there in Discussion Forum land.

I'm in Vegas for the night and flying to Dallas for the NCRS Texas Regional tomorrow morning. Don't have a photo of that part with me. I will get it out to you but it'll have to wait until I return home on Sunday.

the early 56 dipstick was discussed less than a month ago. type in "E1956 dipstick". another dimension that might have helped if you did not have a number is the width. the dipsticks in the 265s are known to be narrower than the ones used on the 283. this is true for the 524 block. i would think the sticks in the 991 blocks would be similiar in width.

Re: Name that dipstick

Very interesting about the width. Didn't know that.

I didn't search for early 56 dipsticks since I had no confidence at to its year being identified correctly on a hand written tag. But frankly I bought it hoping L 55 - 56 was accurate. Not that I need it but just thought it an interesting NOS part at a reasonable price.

the late 55 would be when the 991 block which used this dipstick was produced for 56 cars. no 55 model year cars used this dipstick.

Dennis Clark. The one and only official NCRS "Dipstick"

Please do not use this post as an excuse to hijack this thread I just could not resist.

[Troy P.]

Re: Name that dipstick

OK, in the future I'll address all dipstick questions to Dennis...or his understudy?

Re: Name that dipstick

Troy,

Congrats on posting the dipstick photos.

Nice one piece. The bottom end differs slightly from a known original early 1956 1st design dipstick.

Roy's correct, there's only one "official NCRS dipstick".
