Generation IV External Engine - vic jr questions

Hey guys i originally planned on running a set of ls3 heads with an l76 intake but i've been some what talked out of it due to lack of cash. im running an ls2 402ci motor and i am planning on sticking with my ms3 cam and prc 5.3 heads they both have alittle over 5k on them both but i wouldnt mind changing them out around 20k and possibly going with something a little bit bigger and better so right now i plan on swapping intake manifolds!
does anyone by any chance no how they might work together the ms3 and the vic jr? i was told that the prc 5.3 would be good for that vic jr down low. does anyone have any input

MS3 and a single plane won't match. That cam is way off for a carb intake. A trex is closer to what is needed. Something along the lines of 240's duration and 108 LSA.
