By slick56 - 10 Years Ago Finally have enough spare to order a Mummert intake. Currently running a B intake with 2" spacer; what manifold would i order, the standard or the +1/2" high rise? Will 2-1/2" above stock be too high for torque or power? Plenty of room under the hood with 60's air filter assy. Thanks, Al.  . By Ted - 10 Years Ago Here’s the link to the article that was in Y-Block Magazine regarding 2” tall spacer testing on a Mummert intake.  Spacer design would appear to be critical. http://www.eatonbalancing.com/blog/2012/09/29/carburetor-spacer-testing/  By slick56 - 10 Years Ago Thanks Ted, quite an eye-opener! I would not be making much more than half that horsepower tho... the tapered spacer would add a few neddies, but do i opt for the standard or hi-rise Mummert initially? the cam is a Y-270-S, adv. duration 272*. @ .050 224*, .440 lift C heads with 1.84 in and 1.50 ex, mild porting, milled .025, decked, cast 292 +.040 pistons, I beam rods, balanced, 62 dizzy, pertronix, 16* initial, all in 36* @ 2200, 600 holley vac sec, runs well but the 6litre scrubs are giving me a hard time   . By Ted - 10 Years Ago slick56 (12/27/2014) ....... but do I opt for the standard or hi-rise Mummert initially? Unless you have a ’55-’57 Thunderbird, the general rule is to opt for the hi-rise manifold.  John can correct me on this if I’m wrong but I believe the high rise manifold is only about ¼” taller than the Thunderbird specific intake.
