408 ignition curver advice
The 408 in my Swinger seems pretty lazy at lower rpms and I am thinking its my timing curve . I had the engine dynoed but that only covers 3000 - 7000 rpms .
The build is as follows
W2 heads ported
246/250 @ .050 / .648 lift on 108 solid roller
W2 Victor intake
9.5:1 compression
850 Pro Systems carb
Daytona Sensors CD-1 programmable ignition
TTI 1 7/8 headers with 3” exhaust and crossover all the way back .
My current curve is 18 intial and 32 total . Would 25 by 1200 be too much ?
Looking for more torque in the 1500-2000 rpm range . This thing should melt drag radial tires at will when I roll into the throttle . IMO .
