What is the lift on the factory 2.3 roller cam and how would they do racing in a pure stock class. I have a cam that came from a 2.3 ranger motor and was wondering how it would perform as compared to aftermarket with a .450 lift max. I know it is a great demand on e bay for these cams but didnt know wether or not they are being used for racing applications. Thanks in advance for any advice.

do your rules say you have to run a stock cam?

i believe the last time we checked they were .245 lobe lift and around .390 - .400 total lift at the valve.

Rule for my class do not limit you to a stock cam, they do allow aftermarket with a .450 lift max. which I am currently running a little bigger int. .460 exh. .480 with 286 deg duration. When checked at the intake valve my cam indicates a .445 intake lift. I was just wondering how the roller cam would compare, have seen smaller lifts outperform a taller lift is the reason I ask.
Thanks again for any input.

Lift is not as important as duration.We have to run hydrolic at the track we run this year.425 lift and we turned 8000 last year.

Duration is the key as racer said. win a 2300 most in the mid to later 80's and 90's use a .400 total lift. with my track rules we can go to a .454 lift but i think that this is to big for what at least at out track needs but just a little insight we are useing a .450 with a longer duration but if you bump up the cam remember to strengthen the cam towers and change those stock cam follower's
