OK, I have another question. According to this NHRA spec sheet on the '79 W72 220hp 400 engine, this engine only came with a manual trans. This is also what I've always read.

However, tho this page says "Notes: Class Limits--Available with Manual transmission only", it also lists the hp factor for an auto trans at 270 for Stock, and 285 for SS/auto. So, does that mean you can or can't run a '79 Bird with a 400 and auto trans ?
It seems that if engines are legal in bodies they never actually came in, then it should be OK to run an auto behind an engine that came only with a stick. They say the '77 W72 400 is legal with an auto, only in a Can Am.

So if an auto is not legal in the '79, then do you guys think it would do any good to put in a request(or whatever the process is) to get an auto approved for a '79 220hp 400 Bird ? Maybe nobody has ever tried it. If not, would some of you guys who have a little clout with NHRA, please make a proper request for this ?
It seems to me to be a sensible and reasonable request, considering that they will allow almost any auto, besides what came in your car, stall converters, aftermarket blocks, forged pistons & rods, different rear ends, alum heads for some engines, etc, etc, etc.
Some might say, why bother ? Because there were more '79 Birds built than any other year model. Therefore there are more of 'em for sale than any other year, which, on average, will make 'em cheaper to buy. Hey, even if I never race one, it might help somebody else down the line.
If they are already legal and it is just not reflected on this spec sheet, then somebody please tell me where to find that info. Thanks !
