Title: Cam selection for my 2276 Post by: ianmac on May 06, 2008, 09:48:38 am I took the motor out of my '63 for a good old clean up, its about 10years old, but thought whilst it is out I would go the whole way and strip the bottom end. To be honest I have never liked the FK-87 cam, I always found the engine to be all or nothing. When I originally built the motor I just wanted an animal, now I am getting older I want it a bit more streetable, for this reason I have decided to change the cam.
Spec of motor is: 82mm crank 5.5 rods Jeff Denham 044 heads (44x37mm valves) 48IDAs Do I go for an FK-10 or an alternative? Whats do you guys reckon?? Also would I benefit from dropping to a 1 5/8" header? Ian ;D By the way the car is a full weight street driven '63 bug.

Also, which carburetors are you going to use? 40mm Webers: too small for this cylinder cc really to get hp, so very mild cam timing like no more than 250 deg @ .050 44mm Webers: something like Engle 125 or K8 or FK44 or 86B Web 48mm IDF or IDA: Engle 130, Web 86C or if car is light and has really close gears, FK87 I really enjoy my Pauter R6E8 in my 2165cc, 9.7:1, 48mm Webers, comes on just under 3000, really comes alive @ just under 5000 |
