273 cam suggestions

the 318 is as follows...
-87 truck shortblock W/78k decked .055 (stock cast pistons are at zero deck)
-new rings, stock 78k bearings and oil pump (looked NEW government engine)
-Cloyes double roller
-mopar '759' cam/lifters (0* advanced/retarded)
-smith brothers pushrods
-heavily ported/tapered 87 #302 heads
-70's cast iron spreadbore smog intake
-holley 600cfm 4160
-stock manifolds
-2.5" single exhaust
-recurved dizzy with mopar orange box

Lke I said, put my Cuda at 14.6@97 with a 2.5 second 60' and pegleg 3.23's just wondering if its too much cam for a low compression 273 with stock #302 heads and some work done to the manifolds or headers?
