The na torque curve is the important thing on the street car and the bigger the motor the more torque down low.
Torque also breaks things and wears tires out.

that and shorter rod ratio more torque.

I personally am doing a "mix" of the two. Kinda the best of both worlds is what I'm shooting for but we'll see how that turns out.

Convert it to a nitromethane car and you wont even have to run a radiator. The do double dry-sumps and a 16-injector, four stage set-up run by quad motecs. replace the ignition with magnetos and do away with those sissy DOHC heads and put some F1 style pnumatic valves. Rev to 21,000rpm!!! Thats tyte.
Tune it for EXACTLY 29.8764 psi at 1756.3 ft above sea level.

Or just do a stock bottom Sti bloack and have fun at 25 psi
