71 Starter Number/Date

[Greg F.]

I plan to order a few manuals this week to help me with these questions.

I pulled this number off the starter for my 71 small block. Is it correct and is the second number the date?

1108338

0J 3 4 (is this Oct 1970? what does the 3 and 4 represent?)

Thank you,
Greg

Yes, the GM #1108338 is correct for a 1971 Corvette with 4 speed.

"0J 3 4" indicates September, 1970. Normally, the last digits represent the day of the month, but, obviously, 34 cannot indicate a day of the month. So, it must be that the 3 designates the day and I don't know what the 4 refers to.

Re: 71 Starter Number/Date

There were two starters used on SB MT cars in 1971 (early and late). The 1108338 stater was a carry over from 1970 and was used until around June of 1971 (exact AIM date for replacement release can be found in the 1972 AIM book). The 1108418 starter is the 'late' version.

The date code sequence is explained in your copy of the Judging Guide. The first portion (0 J 3) represents the date of production (Yr Month Day). The fourth character designates 'where made' (plant/line)....

Re: 71 Starter Number/Date

Thanks Joe and Jack. I have an earlier 71, so the that number is correct for me. Thanks for explaining the date code. I thought the "4" might be the shift but I didn't think they had 4 shifts. I don't know...thanks again!
