I agree with you totally Robert with fitting a warmer camshaft before a carb upgrade. NOT a hot cam but something warm up to 270 degrees duration (ie. 25/65 65/25) will wake up an otherwise totally stock motor.
The above mentioned cam will give very good gains with future mods such as more compression (10:1), extractors, exhaust (no bigger than 2"), bigger carb, some headwork, dizzy regraphing and shorter diff gears.
