Best B.O.P. stock and super stockers of all time

There were some MAJOR changes for Pontiac, with the introduction of the '67 models. Many of these changes would affect Pontiac drag racing for many years to come, even to this day.

(1) The 1st 400 cube engine.

(2) The 1st 428 cube engine.

(3) The 1st Firebird.

(4) The 1st TH400 in a GTO.

(5) The 1st Q-jet carb on a Pontiac V8.

As I've mentioned in other threads, I haven't been able to find pics, or other evidence, of large numbers of '67 GTO drag cars. I think Mark posted pics of some.

But, I've found several pics of '67 Bird drag cars from the early years. There were probably lots of others, around the country.

Because the 428 was available only in the big cars, there were apparently very few 428 powered cars on the tracks. I suppose that a '69 GP was about the sportiest body a 428 ever came in.

Because of the current GT rules, in Super Stock, the 428 is now used in several strong GT cars. If somebody wanted to run a '67 428 powered Stocker, IMO, it could possibly be made competitive, with it's current 350hp factor.

2 of the '67 Bird Stockers I'll mention have done real well running a 400, with a current 338hp factor.

Therefore, at only 12hp higher, the 350hp rated '67 428 just MIGHT be competitive. Yes, the big '67 Pontiacs are heavy. BUT, there have been quite a few heavy cars & wagons that were very competitive.

NHRA allows the 428 to use the same 670 heads, with the same 65cc chamber size as the '67 400.

One indication that nobody has tried to run a serious 428 powered Stocker, in recent years, is the fact that NHRA does not list any legal replacement pistons for it.

After looking at the weight of possible '67 428 powered Stockers, I was surprised to see that several models would have a minimum weight, with driver, of less than 4000 lbs. That's not too much heavier than some later GTO's & 2nd gen Birds.

So, looks to me like the only thing that might slow the big cars down is that they produce more wind resistance. Don't know how much that would slow a car down, as compared to a '67 Bird body, with exactly the same engine.

But all this is just my thoughts. Doubt anybody will ever build a '67 428 powered Stocker.
