Yes we can do 6 cyl versions as well but i have no cores so you will need to send me one they will cost slightly more due to haveing more lobes. Yes the base circle does change, not it does not have any adverse affects. There is plenty of preload on the lifters to ensure constant contact betweent he cam lobe and lifter.
im sure its probably pointless, but have u considered making a non-turbo diesel cam.... ive got a modified pump from giles on the way and im curious to see if i can get to 100bhp with a 1.6. the pump alone should get me to around 75bhp. im sure it will require headwork in addition to a better breathing intake and exhaust setup, but id still like to try it
...all cams will be HYD lifter only...
