Cool. Is it the two-valve motor or the four-valve?

Re: to all 85-92 efi racers
 

I used to make my living building Quadrajets, and as I remember the only versions with the stop on the top secondary air valves were the 307" Olds.

Mark,

Thanks for "coming clean." I WILL pay attention to what you have to say, now.

You said, "There IS no problem besides the one YOU want to create."

It just seems to me that when two or three percent of the cars of one type (turbo cars) can nail down over fifteen percent of the #1 qualifying slots at national events, there is a problem in the way things are being done.

If that doesn't ring a bell with you, then we simply don't analyze situations in the same way.

You are certainly entitled to your opinion, and, to post it on here, as am I.

RE the Buicks *Grand Nationals)? They are not a good canddate for this exercise for a couple of different reasons, the first being that they have offset-ground rod throws which minimizes crankpin overlap, making the cranshafts inherently weak and prone to breakage at high boost levels. Better cranks are available, but the stock ones are not very strong. You're right about following along behind with a broom...

The second reason is, that NHRA closely followed the performance of these cars and hit them with significant horsepower, in the past, so qualifying well against their index at the perscribed factored horsepower is not that easy to do. I don't remember one of these cars qualifying #1 at any time in the recent past, do you? The four cylinder cars that usually make the #1 slot theirs, have not been the subject, generally, of such close scrutiny by the HP Factoring Committee, and it's not such a stretch for them.

Like I told Jim Wahl, I can't see NHRA doing anything about this situation, so all my caterwauling has probably been a waste of time, but I felt like something needed to be said.

Thanks again for using your name; it gives you GREATLY enhanced credibility!!!

They never built a neon with a 2 valve head

bill & jim why don't ya'll kiss and make up ghezzzzzzzzzzzzzzzzzzzz

guess we didn't help matters at memphis & atlanta #2 and # " 1 "

charlie still mad boss beat ya out of number one at gainsville other year huh ?


ok all jokeing aside 305's been hit to death did any 350 drivers do it to them ?????

jim aka the guy standing on line watchin the car go fast hehehe

Art,

You said, "They never built a neon with a 2 valve head."

Well, that was news to me. I thought the larger-displacement engine they had was a 2-valve motor, while the smaller of the two had 4 valves per cylinder.

SOHC and 4 valves per cylinder.... I learn something every day!

Thanks!!!

Re: to all 85-92 efi racers
 

Neons didn't have a larger displacement engine, except for the srt4 all neons are 2.0 liters and they all have 4 valves per cylinder.

Mark,
so, where's MY cookie???? :)

Re: to all 85-92 efi racers
 

Art,

I am sorry I muddied the water with my inaccurate information. I thought the more powerful early Neons were an 1800cc motor, but that was only true in Europe, I now find out.

Thanks for setting me straight on the displacement and valve situation.

Now, let me re-phrase my question:

Is your new race car an SOHC motor?

I can't get that wrong...

Re: to all 85-92 efi racers
 

I hope I don't get some of my friends all torqued off by bringing this up.
The 68 Firebirds had a restricted secondary carburetor from the factory. I seem to remember it wasn't the air valve but something on the secondary butterfly linkage.
It seems that there was an edict issued by Pontiac management that no car could have under 10 lbs per hp, so at about 3300 lbs, the Firebirds all had to rated at less hp than the GTOs that were using the same motors. So Pontiac just lowered the ratings and restricted the carbs. That system didn't last long,once the racers realized it was there, as you can imagine.
Doesn't matter now anyway,because you can use a 207 Chevy carb.
