Down to 2 cams

Your total combination is really close to what I use to run in my Cuda. The only major differences were I started with a Comp XE274 cam and always had headers on it. The Comp had lifter problems twice (internal tolerances were sloppy so they bled down bad after just setting for 1/2 hr.) in less than 1000 miles which comp warrantied, but I got tired of screwing with it and pulled it out and put in a Lunati 60404. IMO it turned out a little too big for the stall and gears I had because takeoff was a little soft it but ran real good on the top end. I think the Lunati 60403 would have been a better match but what is, is. IMO since you said yours is more of a driver/cruiser than racer and the stall converter isn't real loose and your running 3.55's I'd go with the smaller XE268, or even better the Lunati 60403. If you decide on tires taller than 27" I'd definitely go with the smaller cam. If your gonna run a short tire the larger cam should work ok
