Hi, have a 648 cam in 1275gt but far to rough at idle ...have also a 286 scatter cam would it be a lot better at idle . Thanks Michael

The 286 is a lot better at idle ,and a lot milder for road use , depends though what you want to use it for . The 648 was a good race cam in its day , but there are a lot of better ones out there these days .Are you interested in selling the 648

Thanks for prompt reply ..at moment in nz invercargill.will be back in rockinham late nov ....only to be used around town here in invercargill ...so would the 286 scatter cam be on par of a 731 at idle which I had years ago and liked.thanks Michael.

731 is a very mild cam,,, 286 is a fairly tough race cam,,, so no,,, they are worlds apart,
but a 649 is also a race cam so no-where-near as smooth as a 731
731 is a baby in comparison

You should put your heart & soul into everything you do.

What Matt said. I think neither of those would suit what you are trying to achieve. You would be better off with something a little tamer than what you have and probably enjoy driving it more as well. Also a 731 isn't the best option either. Far better cams out there for a street car. Your cam choice should be dependant on your engine specs too. No point having a big cam if you don't have the bits to make use of it.

I'm running a GR 286 cam in my turbo motor with wide LCA's to suit and in all conditions it's great, can even do 60kph in top gear no cam hopping. I had a 731 in ages ago and it's aldi a great street cam sort of stage 1, 544 is like. Stage 2/3 and 648 is like a stage 4/5 in my eyes and 286 is like a 4 I guess.

As mentioned these days there are much better cams around, call GR @ Russell Engineering he is the cam/ mini God

yes, Boosted is correct... engine "size" also plays a major part

a 544 or 140 in a small bore (998-1098) will be very lumpy,,, but the same cam in my 1510cc is tame & mild & almost smooth

wide LCAs will tame the cam also, less overlap, less lumpy etc etc etc

no black art,,, just education about physics

Perhaps a 276 may be better suited for this guy?
