G/SA low qualifier at Thunder Road
 

What is this combo? I wasn't even born in 1964.

There is a single 4 barrel 383/330/280 that seems to come close to fitting the class, looks like it might be a good combination.

426 originally 365 horsepower, NHRA rated at 291? And people complain about new cars?

Re: G/SA low qualifier at Thunder Road
 

LIKE!
There is lots of "soft" combos out there. Racers just need to be smart enough to recognize them!

Looks like his cars are always well cared for and don't want for much either. I bet the same car with less than thoughtful testing an prep would be just another .4-.5 under car. It isn't like he bought it complete like the new cars. Going Mopar now 442?

Very well put Sean! There are plenty of fast old dodge combos just takes some keyboard surfing. However, it still takes some work it isn't always plug and play just because it's good on paper.

The 426 Street Wedge is a flat top piston, fairly low comp combo with an AFB that flows 566 and 430 lift hydraulic. From the factory it makes about the same power as a 361/305 which had basically the same carb , heads and cam. If it was such a killer combo, there would be dozens of them out there.

Biggggg differance between writing cars into classes or better yet, reading the class guide and taking advantage. It existed! Hats off to Jim and his guys.
FX_@NHRA.com Fix this please....

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.

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.

^^^^^ What he said!

Re: G/SA low qualifier at Thunder Road
 

Not sure if this combo being discussed has them, but, Mopar also gets Edelbrock Aluminum heads.

Oldsmobile?
No can do.

Re: G/SA low qualifier at Thunder Road
 

with those heads your talking about you also get weight and horspower.....If i read it correctly

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!!!

Re: G/SA low qualifier at Thunder Road
 

Yes,you are right, 5 horsepower.

I guess this isn't such a good combo after all.

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.
