Stockish 340 upgrades, cam needed

Sorry I was thinking of RAMMS tread, the other 340 but stock manifold thread
he will not be needing exhaust split with those heads and headers
let's see what the compression really turns out to be
right now i'M THINKING 9.5 4 SPEED 3.23 GEARS
9.5 this is easy
10.5 will take some work
can't really do more duration because of the gears and 4 speed
so spread the lobe centers or???
Rattler type cam is for low compression not this build I do not think it has Mopar lobes either

some comparisons with a similar seat duration Howards Mopar lobe
340 Whiplash ???? 223 550 107 LCA no idea seat duration

Thumper 279 227 .486 107 LCA IC 63 ABDC

Rattler 281 227 .480

Howards 279 256 232 152 .357 .535
No question you could build a more powerful cam without the gimicks
