depends on what you want from the car. If you like low end grunt and an engine that stops delivering at 6-6.5k it is a good choice. if you want something a bit more race with more peaky higher power I would get something a bit more "wild"

like a 286 cam?

you will find the sw5 is a cracking cam, i would leave that in and see how you like it ......?

time the cam in at 107 that will allow 1 deg for stretch

the 286 in my book is a little OTT for the road best suited to track racing

you will enjoy the performance and tractability of the sw5

ok i just thought that the sw5 is a bit wasted with the high cr and the fact it revs up to 7000rpm!

Because it can run up to 7K doesn't mean it needs to.

Never used a SW5 but the way I see it, big capacity and high CR should make up for the lack of drivability of a bigger cam at low revs.

As Steeve wrote, I would use it before deciding to change it ot not ...

Sorry to be a bit of a na sayer but IMO the SW5 has no place in a big bore motor it is perfect for hot small bore motors, but it lacks Lift and duration for a big motor IMHO. the Kent 266 is the best big bore cam for street use it gives a fantastic power curve and a mind blowing amount of torque My last 1480 had this cam with a set of twin 1.5 SU and a good head and made well over 90 ft/lb torque at 3000rpm an animal of an engine I loved it and wish I never changed it for the 286 although a great cam for fast road track it just never had the feal of the 266.

i have driven it with the sw5 in it, but just thought with the high cr it could benifit from somthing a bit more livley.
whats the sw10 like?
