I'm not a big fan of 347 or bigger budget small blocks. I would say stay in the 302-333 ci range, work over some 289 heads, 11-1 comp, RPM intake, big ass carb, cam that peaks somewhere around 7500-8000 RPMs. Then put it on some gas.


also recommended for 400 hp:

headers, e fan, ignition, decent rear end, locker or spool, sub frame work, probably air bags, brakes, tires, clutch, decent gauges, AND mufflers and more
why air bags?
