i like the LT1 cam with the 1.5 rockers. to take advantage of the LT4 + 1.6 rockers you are gonna want better heads or need to sink some cash into more head work. if the idea is a budget build up, that would pretty much blow it right there. the LT1 cam is also easier to find around in he 30-50 buck range vs the $100+ you can expect to spend on an LT4 cam unless you get very lucky.i would ao suggest stepping up to a good set of headers and 3 inch exhaust. the warmed up engine will thank you for it.
