some builds go long duration cam,big port heads,big carb etc which make an impressive hp number (at high rpm) but idle quality and lo rpm power can be disappointing without a gear and a converter.
I concur
The way I see it if you ain't gonna gear it don't build especially with small displacement. You either got to build torque in the engine ( displacement) or in the gearing. Most run 3.23:1-3.55:1 that's what they should design their engine around that's why 408 are so popular.
