Just gonna give it to you straight …. Just because your car runs close to the 1/8 mile index DOES not mean it will run close to the 1/4 mile index AND have you weighed the car yet ??? Number two ..:: stockers are all about RING SEAL .. just remember that. … Cheers…..

Mark Lewis put the engine together for me, I think he did a great job with what he had and I trust the rings are sealing properly. I haven't noticed any extra blow-by, the valve cover breather has 0 signs of oil comin out of it after 4 1/8 mile passes. Also, I understand that this car will not backhalf and pick up time in the 1/4. I figured I'd have to go at least .10 to .15 under the 1/8 mile index to get under the 1/4 mile 13.00 index for N/SA

You need to try another q-jet for comparison, I thought I had a good one, borrowed another and was 2 tenths quicker. Also, most jet tuning is with secondary rods.

I'm not a real Q-Jet tuner, but I question the 6.5 lb fuel pressure.
N/S area vs the small float What do the experts say about that? I have had Q-Jet customers that are very particular about regulator location and fuel line routing to the carb... OK What you say Q-Jet experts??

OK What you say Q-Jet experts??[/QUOTE Quadrajet fuel pressure depends on the needle & seat size. They are available from .110 - .150. The .110 can handle more pressure than the .150. My choice is the .135 for all applications. It has been used in two of my Super Stock customer's cars who have run in the 8 second zone. You can safely run 6 - 6.5 with it but I have fast customers who only do 5 - 5.5. You will have more problems with too much pressure than too little. A well designed fuel system will go a long way in not creating problems you may attribute to the carburetor. Locating the regulator ahead of the carburetor and allowing inertia to work for you is a plus. |
