What is your goal?

Seen ya start a ton of threads on 318 mods.
Looks like you want a mild torque engine aka idle to 4500 rpm.

First torque is mainly a product of displacement it generally ranges from low of 1 to max 1.67 lbs-ft per cid a mild engine is generally gonna fall in the 1.1-1.19 lbs-ft = 350-380 lbs-ft for a mild 318.

I like the 318 and think it has far more potential than most but that ability comes with rpm's, hp what moves drives accelerates your car and is a percentage of torque at different rpm's. In the range we care about here, hp is 50% - 100% of torque from 2626-5252 rpm's a 1.9% gain for every 100 rpm's. If your ok with those limitations fine but if you really want better idle-4500/5000 rpm power add displacement. Through cid and or blower/turbo etc..

My main goal is to have a car that has good throttle response and low to midrange torque, have the ability to get out of its own way and to have some stop light to stop light fun once in awhile. Idle quality is not a issue but to have a good torque cam means a smooth Idle, I wouldn't mind a little rumble at the pipes. From the research I've done looks like the engine will mainly be off Idle to like 4,500 - 4,800 rpm's. I may be wrong here but aren't most torque cams have a max duration at 0.050" of 204* / 216*?
