So he you small block guys go. 69 340, 10.5:1, mildly ported J-heads, 1.6 roller rockers, RPM air gap, TTi headers 3" X-pipe, MSD distrib, 727 with mild stall and 3.55's He wants to keep the 3.55's. Now it has the stock 340 cam. I got the thing to run 13.80 w/ a 750DP and 14.08 w/ a carter 600. Carb recommendations taken too.

I recommened a 650DP but then again I don't care for vacuum carbs. I'll check into that cam.

Out-powers all others! This High Performance street cam likes 2400 RPM stall, 700 cfm carb, dual plane intake and headers. Makes un-equaled power to 6200 RPM with proper valve springs. Very strong cam with great street manners. Advertised Duration (Int/Exh): 268/276 Duration @ .050 (Int/Exh): 226/234 Gross Valve Lift (Int/Exh): .494/.513 LSA/ICL: 110/106 Valve Lash (Int/Exh): Hyd/Hyd RPM Range: 1800-6200 Your life is not my fault. My life is none of your business. Speech is free only if you agree with those in control.

Excellent idle and in-gear vacuum (11-3/4"hg in D)and it pulls past 6k. Very good street manners. 1970 YO7 A66 [Canadian Export] F8 Challenger 340 (Currently in shop for stroker assy.)
