LA 318 w/ roller lifters&cam - Waste Of Time?

OK, my decision is made. I am leaving the bottom end alone in my 72 318 with only 84K miles, and dropping in a 318 whiplash cam. I don't have the time or budget at the moment for a complete rebuild.

One question however,
because I also have 360 heads (308 cast) with DP Weiand and 650 eddie, will all those features help me or hinder me slightly, considering the cam I am choosing. I am guessing it is all good.

Actually, one more question,
with 3.23 gears behind my 904 auto, should I also replace my stock converter? Not right away, but eventually.


thanks
Whiplash cam , do some work on the 318 heads , or you'll have to shave the 360 heads big ,don't forget to change the timming chain , those plastic gears get eaten driving hard , thermoquad works really well on a 318 , I had an 850 off a 440 on my 318 with cam headrs and shaved heads and it ran with 400 birds and 396 chevs . Car would melt those G-60 bias ply Goodyear tires , also broke 3 71/4 diffs before I put in an 8 3/4 with 3.23 gears .
318 are decent motors , done right they have lots of go . Nothing wrong with them
