Have any of you tried, used, or are using these Air Cleaners on the Holly 4000 tea-pot 4bbl carbs. on your y-blocks?  I am interested in using them on my 312  2x4 build. I have an Edelbrock 257 intake and a pair of 56 bird carbs, and a pair of 56 Lincoln carbs. I have not made a decision as to which set of carbs to use. I will
 probably experiment with both.  anyway I am looking for some feed back on the air cleaners, as how they fit, are they to restrictive? etc.  any help or information would be appreciated. I like the "D" shape of these air cleaners. any air cleaners I use will have to be able to clear the radiator support rods on my hoodless and fenderless  chopped and channeled coupe.   Thanks for any help anyone can provide.-------Jim          http://www.spotlitekustomaccessories.com/store/p7/V8_Dual_Quad_Air_Cleaner.html
