Hi all i am thinking of fitting a 649 cam in my 1340cc S fitted with twin 1 1/2" H4 carbs 1.5 roller rockers , could i get away with a 3.7 diff ( for limited road use only ) i know the works cars used 4.1 but this would make it a screamer especially with straight cut box and drop gears . Your thoughts please .
Best Regards
