Re: What class would a 66 427/425 Biscayne have run in
[ QUOTE ]
I have a 66 Biscayne 427/425 Biscayne and would like to know what class it would have been in in 1966. I have had mixed opinions and thought I'd turn to the experts on the SYC. Thanks in advance, Dave L. SoCal [/ QUOTE ] My original NHRA class guide shows 8.56 for Stock and 8.66 for Super Stock...I didn't bring any rule books with me to Michigan, so someone with a '66 book handy can chime with what class those factors fall into.

Re: What class would a 66 427/425 Biscayne have run in
I don't have the NHRA books but here's what I found in the 1969 AHRA Rule Book.
Formula/Showroom Stock Class: B/S B/SA Hot Rod Division: Single 4 Bbl puts you in Formula 2 and Multiple Carbs/Factory FI/Factory Supercharged bumped you up to Formula 1. The 8.56/8.66 factor puts you in C/HR. The 1967 AHRA Rule Book shows the following: Showroom Stock: A/S A/SA Factory Production: FP/DS Formula 2 Hot Rod: B/HR Modified Production: B/MP Sorry but I don't have a 1966 book.

What is the deal with the crunched car next to yours in the first picture?

[/ QUOTE ] Ok, had a chance to grab my '66 rule book...woulda been in A/Stock (7.00-8.69). I forgot there wasn't a Super/Stock class per se *yet*, so the 8.56 factor would've been the one you'd have used in '66...
