    In Jim Wangers book, he said they discovered this (air cleaner base only) when they took the new 400 Firebird racing in the stock class. It went fastest with just the air cleaner base.

    Scott, contact Oldschool85 he had 1000 TQ for sale a little while ago here on the board rebuilt by Norm Dile and never ran. Unfortunately Norm had passed away years ago.

    My modified 850 TQ wouldn't run right without a nice smooth base. Quadrajet didn't seem to care.....

    My mistake. I assumed when he said he had an 850 TQ I thought he had the 850 Competition Series carb. I have one on my '76 and it loves it. I've have both and at this point the difference is nill. The physical difference between the 850 and the 1000 is the double ring primary booster and very slight primary venturi compard to the non-existant one in the 1000. If you could get a 1000 I'd get one.

    Edelbrock would have done the BBB a better service to make a Performer RPM Airgap instead of the heads and they would have sold hundreds and hundreds. Way more than they ever will sell of the heads.

    Yeah Mike, years ago I called Edelbrock about making a Performer RPM....they said market too small not worth it. Then I said but you make it for Pontiac....and AMC.
    Geez they think AMC market is bigger than Buick???

    Contact JollyGood on here for a fabulous deal on a very clean anular Holley 1000 he has for very reasonable $. It was slightly too much for his 462.

    Scott, I think you’re past the point of the stock oil pan.
