I need opinions on this 318 build

Rowdy.. I like that term! LOL

Durations are 292 advertised, 244 @.050"; it's is gonna have a DCR of LESS than 6.0..... that will make you need the patience of Job if you drive off from a stop normally or pretend that you have a 170 /6.... it'll take some goodly RPM's to come up on the torque curve. And fuel economy will not be good. This is a head/cam combo for the strip. And the carb does not really match up well IMHO; it is better matched to a smaller cam.

Perhaps try it and see what YOU think. I know I'd not like it for street use; I would expect it to bog before taking off rather than leaping forward at the touch of the throttle, unless you rev it with the brakes on, and then hit the throttle to get up to the TC locking and the rear wheels spinning to keep the revs up to be on the torque curve .... not my idea of street driving. But, heck, you might like it fine.

Your static CR (SCR) is around 7.5 to start with which is lower than a stock 318, and putting in the large cam kills the dynamic CR (DCR) and low RPM torque. It's gonna take a very small cam to get the DCR even up into the high 6's. Even 256 advertised duration cam with LSA at 112 and a 104 ICL, with .028" thick head gaskets, will get you to a 6.7 DCR; you cranking compression will then be the same at a stock 318, so you could then expect a similar low RPM take-off torque if you had the stock TC. (Which I know you don't; this is just a point of comparison.)

Have you considered milling the heads? That helps to partially address the basic issue: low SCR. That will help for all your planned uses. I'd be looking at a fair amount, like .040"-.060". A .050" shave on the heads would put your DCR into the 7.2-7.3 range with the small cam mentioned above. More torque than a stock 318 now. And with the higher stall TC that you have, now you can move back up larger in cam, and not compromise low RPM torque so badly, and get it to take off better.

And BTW, I have had your engine..... 7.6 SCR with a 300 duration cam..... it did not get up on the torque curve until 3800 RPM. The only thing that saved it was that the engine was good to 8K RPM all day long, and I raced it. But driving around, if you pushed on the throttle at 2500 RPM for example, it would just look at you and go 'blaaaaaaahhhh' for a while....
