Re: G/SA low qualifier at Thunder Road
All the 383 Dodge and Plymouth engines from 1963 to 1967 had an almost flat intake, 550 cfm afb carb, small exhaust valve heads, and a 430 lift cam. The factory rating horse power was to help in the showroom. Paul covered the 426 street wedge. Hats off to Jim Hale and John Shaul who found a way to make these combinations run very well. A lot of R&D. Not a fat wallet.

Re: G/SA low qualifier at Thunder Road
I wish NHRA would de-rate the Olds 400 engines. I haven't seen any in NHRA since Sam Murray's car in 2006. There are a number of old combinations that would be good to see out there but they were factory rated for showroom appeal and are too high for today's competition.

Re: G/SA low qualifier at Thunder Road
NHRA will not derate combos at will. They rely on statistics. If a combination is run and it meets the criteria to have hp removed and it is requested, it will be removed. Read up on the AHFS at nhraracer.com.

Re: G/SA low qualifier at Thunder Road
I think Edelbrock sells some Oldsmobile heads. Maybe you should write NHRA and see if they would consider allowing them Daryl. It can't be too easy to find good cores anymore. Pretty good case for allowing them. Heck, it is hard enough to find SBC stuff, some of the BOP stuff is getting rare.

Re: G/SA low qualifier at Thunder Road
In my case a 29 HP penalty and the Edelbrock aluminum head is NHRA approved but NOT LEGAL AS SOLD!!!
