I would agree with Ryan. To get in the 10's it will need more carb.


Mine has a solid flat tappet, ported factory heads and has gone 10.52 @ 126 with an old 750 dp. Only mod is a milled off air horn. It has gone 6.59 @ 104 in the 1/8 with that carb, which would be close to 10.40 in the 1/4. The cam at the time had 263 dur @ .050 and 607" lift. If everything is working good together he can reach the 10's with a 750 with some tuning.
