Building a 340 - 360 is fairly straightforward. 273 -318 are not that's why these threads go on forever and comes up with no conclusion but also why they get more views.
!st problem should build a 360 crowd starts and cause that argument, thing is their right but if someone wants to do a 318 there a very capable engine and that's their choice.
2nd is most are just looking for mild cam 4bbl and exhaust which your recommends are perfect, but you get not enough cr and displacement crowd talking them out of any mod.
3rd is if you want more power than the 2nd will provide, you got to do something about the heads and cr which most want to do on the cheap so it becomes a problem.
4th way is to build like it's a 340, with a little more gear and stall, which it becomes a pretty straightforward build.
And to the OP if this is for a 318 why the 108 lsa??
