The Search for a Original BB 427 Begins.

Originally Sent: Monday, 28 November 2005 2:42 PM


I decided I wanted to go a big block, I have the opportunity to so why not.. if I wanted to build a small block car I'd go something cheaper...
And the BigBlock I decided upon... a 427.

They came out in the special edition Yanko camaro's so I could get away with it if I had any questions from the Authorities or Vic Roads..I can say it was a factory/dealer option

Anyway, apparently it's hard to find original 427's.,. there are plenty of 454's that have been down stroked (which is a last resort for me), since they have the exact same casts it's just a matter of changing the crank. and that's it.. (as far as I can tell from my research and questions)..

Anyway I've been looking for a few and any that do come up are very expensive (almost as much as I paid for the actual car)...

I constantly have with me a 427 "bible" that I can quickly index to check if it's original or not.. don't ask me why I'm being picky.. but I just am....

Here's an example of one of the first apparent 427's I checked out...


Casting

Casting Number 3963512

From this we know:

It was produced between the years 1969 – 1972

Can be either a 427 or 454

Can be a 2 or 4 bolt main

Suffix Code


T02I3CPD

(as it can be seen it has the layout of the post 70’s code of ‘F0114CMB’ and not the pre 70’s of ‘F0114MB’)


From this we deduce

T = Engine Assembly Plant Tonawanda Engine Plant
02 = Assembly Month February
13 Assembly Day 13th
C = Motor Division – Chevrolet Passenger car
PD = only on 454



(codes shown include motor division i.e. CPD)
