I guess I picked a Bad time to ask....but I was thing you worked at or for Indy.But if Indy has not started making their Mega blocks with the Big Cam bore it would help out a lot of us True Mopar racers.Being able to use the roller bearings is nice but the real need is having a bigger cam core when you go over a .475 lobe lift is very helpful.Going up to a 54mm camshaft allows you to increase the lobe life another .025-.030 and the valve train is as stable if not better than @ .475 which is about the max with the standard cam core.But with the machine work & LSM(the only one I know who makes a camshaft)its about a $1,000 up grade.If you are going to have a Fast Mopar Indy is it! I'll race them B1's and beat them!




Indy has done several World blocks with a 55mm roller cam. I believe Comp can make you one also.
