If You know that intake, You know what #3 looks like, this will need a custom a/c support to use it.
I can tell You it pushed a '73 Satellite that scaled 4050# at Quaker City empty w 1/2 tank + a 300# driver to 100mph with a 280/.470 Purple Shaft. Running pig-rich (unexpected when He added an Extreme K&N top), so not near dialed in, & certainly not a hot set-up. 750 3310 Holley, 9.8:1.
