| I just got done rebuilding my 1600. Have original (30 years old) Weber 34 ICT’s installed on short manifolds with a phenolic spacer. Have a balance tube between the manifolds. Ported and polished heads, 8:1 compression ratio, Scat C20 cam, Empi 1.35:1 ratio rockers. 009 dizzy with pertronix module and 45 k volt pertronix coil. Dual quiet pack exhaust. Current jetting is .055 idles, F6 emulsion tubes, .145 mains, and .165 airs. Running plug gap at .032. At 3k rpm, exhaust seems to not be a solid sound, but rather seems to have about 30% “weak” tones, like 70% of the time it runs strong and the rest is weak. Any suggestions? |
