Are these worth the $$$$?

Bob West Apr 11th, 06, 11:09 PM I've heard they work on the regular VS or DP carbs better than the HP and Dominator carbs. The latter don't have choke horns and are smoothed for better flow already. ChevelleRob Apr 11th, 06, 11:25 PM I bought one for holley's with milled choke horns, I ran it with inconclusive results as I had some other "issues" that day. onovakind67 Apr 11th, 06, 11:29 PM We use a carb hat on our 2-bbl and it's worth about 8 rwhp. The K&N Flow Control setup helped to the tune of 18 rwhp on a 4-bbl 331" SBC. Rich-L79 Apr 11th, 06, 11:52 PM If you have a drop base air cleaner (such as a 66-69 stock open element air cleaner) it won't fit unless you run a taller air cleaner element. 69-CHVL Apr 12th, 06, 7:16 AM Does that aircleaner base sit on top of it raising the whole assembly? bracketchev1221 Apr 12th, 06, 9:44 AM No the stub stack sits inside the air cleaner housing. 69-CHVL Apr 12th, 06, 12:47 PM Is the Mr. Gasket version the same anybody know? bulb122 Apr 12th, 06, 3:45 PM As mentioned above, it fits inside the air cleaner base. I too noticed that it was pretty close to the air cleaner lid, and didn't have the recommended clearance. I changed to a k&n filter top to take care of that. Not the cheapest route, I know, but it works (and looks cool.... :) ) 69-CHVL Apr 14th, 06, 9:01 AM Anybody know what the recommened clearance is? I'm not sure I can get anymore aircleaner in there. bracketchev1221 Apr 14th, 06, 9:39 AM If that's the case I think I would leave it out. My friend ran a moroso air cleaner and it was close. The motor wouldn't go over 6000rpm. Without it the motor went to 7000 without a problem. 69-CHVL Apr 14th, 06, 10:12 AM If that's the case I think I would leave it out.

Without it the motor went to 7000 without a problem. :eek: Rich-L79 Apr 14th, 06, 12:47 PM I believe Holley recommends at least one inch of clearance between the vent tubes and the air cleaner lid. With a stock drop base air cleaner (66-69 open element type) you are already tighter than that. I tried a stub stack and with it in place I couldn't even get the chrome lid on at all with a 3-inch air filter element. You'd need at least a 4-1/2 inch element to provide adequate clearance. ratuned Apr 14th, 06, 2:27 PM i use one on a stock 750 dp carb. but i use a 4" tall k&n filter element. i would try to borrow one or buy a swap meet one first. mike 69-CHVL Apr 14th, 06, 2:32 PM I found a new one for 20.00 shipped, but I think I'm gonna take the advise here and check some clearances 1st. | ||
