*continued from above post.
Heads Casting No.
*was pulled from the left side head between the first and second cylinder (in the row).
Can be either out of a 454 or 402. If this was the only thing that had a 454 next to it I wouldn’t be worried, as allot of 427 were changed over to the bigger 454 heads. But it wasn’t.
Production Date Stamp
Had the date stamp of ‘A27*1’
From this we can say it was produced:
A – January
27 – 27th
1 – 1971
January 27’th 1971
All this can also be checked on this site: http://www.nastyz28.com/bbcmenu.html#engine
Also the engine number..
*Engine number (found next to the suffix code)
(last 3 digits removed for privacy)
1 - Chevy
1 - 1971
L – Vehicle Assembly Plant – Los Angeles, California
– Partial Vin number
So by doing all this I concluded that the motor was a 454.. Maybe (but a big maybe) it is a 427 but I wasn't going to rush myself into it.. I have plenty of time until I need a motor...
