    I know as far as a roller cam. I can have a cam ground to a 4--7 swap. I know this would be a great help for my buick engine or for any buick engine. But I have no need for roller cam for my engine. I believe it would be a great improvment and is anyone selling a basic 4--7 cam. And why aren't any of you guys using them? This firing order has been used since 85 in NASCAR. It relieves stress om 2 and 4 mains and generates a smother tourque curve through the crank. Looking for a cam of this sort for a 11 sec combo. Drivable!

    How much hp are you planning to make.The average 500-550 hp buick doesn't turn enough rpm to see the gains from this set up.A nascar turns 9000rpm for 500 miles they need all they can get.These guy's fight on the dyno for days to gain 10 hp.
    I don't know of anybody that has run a swap cam in a buick.As I mentioned on another thread we will be in the new block.I might be interested in having flat tappet cores made after the roller cam deal goes through but there would need to be enough interest in the project to make it happen.
