Using the cam you have, 90mm x 66mm, CR 8.5/9.5:1, 40IDA Webers, 32mm venturies, 150 mains, 180 airs, 55 idles, F3 emulsions, will make a nice quick, pleasant to drive, street 911.
For track use hotter cam, higher compression, maybe 34mm venturies, 155 mains, 200airs. These are starting points, subject to change based upon dyno readings, plug readings, etc. Have fun.
'76 911S 2.7, webers, solex cams, JE pistons, '74 exhaust, 23 & 28 torsion bars, 930 calipers & rotors, Hoosiers on 8's & 9's.
'85 911 Carrera, stock, just painted, Orient Red
