road car cam for my 318

so you're saying no 3/4 race cams then?

a stock 360 2bbl would probably work great for your application, 410/412 252/256 (for the earlier 71~74 and then 410 252 single pattern after). the melling 23103 specs out at 410/412 with 198/199 @ 50, though their advertised shows 278/282-- which i don't believe for a second-- on a 110 which is perfect for the use you're looking for.

i like the purple shaft P4452755 if you can find one. it's .405/.410 240/248 yes, i know it's smaller than the 360 2bbl cam but it slap *** works in a 318. with the performer and small heads and reasonable carb it's gonna make a ton of low end and pull vacuum while idling like a sleeping kitten.

a little more spicy, the howards street force 1 would be a good choice. 420/430 and 259/267

if you're okay with comp's units they have a tremendous offerings of XE and DE cams that are right in the wheelhouse for what you're looking to do.
