Anyone use them for a custom BBC grind? Otherwise who is recommended these days.

I use bullet if its custom and isky or crane for off the shelf.I like getting the double swaps from bullet.

Sorry, I couldn't help myself.

whats Bullet's approx. cost for their billet cores

what is it about the swapped firing order that you like?

I know that that Bullet keeps the nice Callies cam cores in stock. As far as changing firing orders, you really need no other evidence than the fact GM saw enough of an advantage (albeit likely very incremental ) to change the firing order in their latest gen motors. If you are running a carb, supposedly there is an advantage to be had in fuel distribution.

I like the grind you sent me that was from bullet just want to change lsa to a 110 or 111. I would imagine that will probably change the valve timing a little. I wasn't sure how much input they'd have on pertaining to my specific builds but would only make sense to call them. I should have thought of that. Thanks! I saw some 565/572 builds that had little more duration and close in lift making close to 800 @ 6,300.

I would like to see what duration they'd put me at with a solid roller. There has been some who have used the 1075sci cam with NA build and claimed good results however I don't have first hand knowledge. Only read it on an old thread here.

I cannot comment on their boat cams but I had a custom grind done for my 565 bbc drag race motor and it works really good. Better than the erson custom grind I had before and nice people
