508 mopar cam

I have a 360 that was rebuilt with a Summit kit that included pistons. the block is a 76 truck block that was bored 40 over, rods and mains were 10, stock rods, heads are a set of late model (non magnum) 318s that were ported on bolth sides and have the big valves and high lift springs(not sure what size). The cam i was running is a custom grind that is just a hair bigger than a 340 cam. There was no milling done to the block or heads.
I have a mopar purple 292/508 cam with hyd. lifters that was broken in and has only 4 passes down the 1/4 mile before the guy yanked it out cause it wasn't big enough. I also have a Eddy street T-ram and 2 450 holleys. Anyone forsee any major problems with putting the 508 cam and T-ram on the motor? I am wondering about HV oil pump (would I need one with this cam?) and pushrods but I can get a custom set from the local cam place if I need to. I also have a carter HV fuel pump.
I will be running a 518 OD tranny and a 8 3/4 with 2.7something gears (for now), this is ganna be a fun driver that may see the 1/4 mile about 2 or 3 times a year when done.
