318 value

money and hassle. straight up.

you have a 318 2V car now think about what you need to get a BB in there:
mounts- 150~250
transmission- let's say you get lucky and score a $500 cast off
exhaust- what's the cheapest headers gonna run? maybe you scoop a used set for $500?

then: do you need a better radiator? does the power booster fit? power steering? gonna need to get that oil pan that fits and make sure your steering linkage is right. brakes up to the task?

so you're easily 1500 into it before a motor and other assorted sundries.
I get that, my point how many times you see people say they want great idle-4000rpm performance with highway gears, stock stall great drivability etc.. But want to get it out of a 318 or something like that.
All that spells out run more displacement, most only seem to think of displacement is when you want to make over 450-500 + hp not 300-400 hp obviously you don't need it to make this level of power but it's gonna be the most streetable way to get it. If you build it big enough 2.76 gear and a 2000 rpm stall could be the optimal gear and stall for the quarter mile and be mild as can be. There's a reason Cadillac built a 500 engine, Smooth street friendly power.
