1" Carb spacer or not?
Just wanting to get some imput from anybody with carb. smarts. I've got a 388 sbc Eagle rotating assembly, 6" rods, solid cam, 544 lift with 256 duration, 108 LCC. Dart 200 angleplug heads, 9.6 compression. Victor jr. with a 650 Mighty Demon. Would a 1" spacer help my engine combo on the street and on the track? It runs really strong on the street right now, dosn't load up too bad just puttin around town, and is very responsive when given the chance. Thanks. Trond...

Each individual motor likes a different spacer or no spacer. My RAIV 400 Pontiac motor with a 73 SD Qjet, 72 HO intake picked up 8 hp with a 1/2" 4 hole. Friend true 72 HO motor with same carb model, same intake different heads, cam and CI lost HP with it! Just got to try them.
