421 production numbers
 

anyone know where i can find these online?

Are you looking for a specific year or engine option, or just for all 421s ever built?

numbers
 

wondering how many 421 ho's made in 1966?

Around 500 YKs (Auto A/C). Not sure about the others

actually looking for info on YJ. sorry, im sure when i put HO everyone thought 376hp

63 421 HO's
 

This is from memory (off my PHS paperwork) so it may not be 100% correct, but in 1963 there were approx 242 421 HO's built. Bonnes, Cats, etc ...

Just FYI

not to hi-jack, but...
 

Wow that is a low number. Thanks for sharing that, Bruce!

I thought the number was higher than that just for the 08b and 11b s. But im good with your number and will throw it out at the wife every time she sees a 421-related charge on the visa.

Eye candy anyone?

That is some SWEET candy! Love the air cleaners, BTW! (FWIW, my 421, built in OCT of '62, is an 11 B/T and is going in my '62 GP.)

gentile3, maybe you can call/email Rick Gonser in the POCI - he is a tech advisor and may have access to production numbers for your block code.

Great Pic ! I'll pull the paperwork out with the #'s and post when I get home this evening.

OK ... 1966 421's are as follows:

421 4bbl auto 7361 (YH, YT, YZ)
421 4bbl manual 1896 (WG, WK)
421 tri power auto 993 (YJ, YM)
421 tri power manual 547 (WH)
421 HO auto 562 (YK)
421 HO manual 520 (WJ)

These number include all Police Car engines.

I was so wrong ...:-) 63 Engine Production Numbers
 

Ok ...I was wrong ! It shows that I mentally blocked out ALL other 421 HO's that were not like mine. Attached are the 63 Pontiac Engine Production Numbers provided to me by PHS.

08B's and 11B's were much higher Bob ...(don't tell your wife :-) )

I remember thinking that 262 was a low number of 421 HO 3x2 automatics made when I was hunting for a 50Q block way back in 2003. My car was missing the original block and I wanted to find a real 50Q ....spent a year or more hunting on ebay. Purchased a 64 421 3x2 auto block (forget the code) when it became available and the logistics of getting it were right. Then ....not 3 months later a friend found a 50Q block for sale on ebay ...and I had to have it. Think I drove 1800 miles round trip to pick it up.
Ahhh ...the good old days of parts hunting !!

Just an FYI ....from the production # sheet

421 HO A 3x2 28G 444 is an Auto in a Catalina/GP -RotoHydramatic
421 HO A 3x2 50Q 262 is an Auto in a Bonne/StarChief - SuperHydramatic

421 HO A 4 47Q 155 is an Auto in a Bonne/StarChief - SuperHydramatic
421 HO A 4 25G 275 is an Auto in a Catalina/GP -RotoHydramatic

I came up with the same numbers, but have the HO numbers switched.
520 for the Auto (YK)
562 for the manual (WJ)
