Hi all,

just finished installing a12 into my off road race buggy and need to know what cam to run.

It is an a12 with forged 40"flat top pistons, balanced everything, A14 head ported and polished and port matched to twin 40mm webbers.

Is running great with the slightly hot cam that came with it before I rebuilt it but feel there is more. It idles very easily at 700 rpm and seems to start to make more power around 3000 rpm and revs okay but not heaps.

I dont have a dial indicator or degree wheel so cant work out what it is.

Anyone know a grind that might work off the shelf?

Also is it possible to change cam without removing the head? Magnets to hold the lifters perhaps?.

And finally is it true that there is a crossflow head to suit the A12 and if so are they of much benefit.

Cheers
