Re: Is the 307 combination as Terrible as what Ive read ?
 

Ya know, the best 307 combo would be a 71-72 Camaro. It fits U at 168 HP.

Thanks gentlemen

Im actually talking about the

1973 - 307 Nova

They have it at 195 HP

That has it falling in P/SA which has a 13.45 index and this ex Jim McDonald Nova hasnt even made a 13 second pass even with good parts in it. When he ran it it was a T/SA. I asked NHRA if the 195 is a misprint because its ludicrous to have this car factored to 195

Apparently it happened on 9/27/01

Does anyone know who it was that got the combo hit that hard ?

Not exactly the way it all went down..
The original 307 was at 200 hp
The 73 is actually showing the de-factored (SS) rating of 195 ,only .
All other years have S and SS split ,with lower ratings for Stock, in most cases
The 73 supposedly has a tad less compression but I don't see it as correct, in actuality.
The case could be made for the 73 to be a few hp less than Billy's 165 rating
But good luck .There are entities involved are going to make this a lot more difficult than it should be.
Are you an NHRA member with a Stock permanent number? You might be able to clear this up somewhat, by next year.
Meanwhile, I wouldn't spend a dime on that combo.

I believe that I've had my hands on this car at some point in time. The 73 307 is the absolute worst of all the 307s. It's the only one that has to use a 350 (993) head with big valves and big intake runners. Everything that a small carb, low RPM combo definitely doesn't need.
Best option? IMHO, run the 350 2V combo at 224 HP. It's not as good as the 69/70 2V deal but it uses the same head (993) and the 1.250v carb. I remember this car being a hatch? It would fit M/N/O.

also easy to maintain during winter storage!
