Quick cam question
Wonder if any out there can give their opinion of a pair of cams.
I am looking to upgrade my Cobs 460ci cam and I am looking at Competition Cams Xtreme Energy Hydraulic either 274 or the 284.
Remembering the UK we have more that our fair share of bendy twisty roads and very little long straights, and a lot of sitting at lights and behind traffic, I wonder if the 284 might be an over kill.
The engine spec is:-
Std 460 block honed
Holly 750
KB 137 pistons flat top with valve cut outs
Edelbrock Performer RPM inlet
Edelbrock RPM Performer alloy heads 75cc chamber complete with 2.19 inlet and 1.76 ex valves.
Scorpion roller rockers which I believe are 1.73 ratio
Comp is approx 9.75 to 10
Just wondering if any of you use any of these cams in the 460ci in the Cob and what you think of them before I buy.
Thanks
