its a chevy motor , already the 318 is a better designed engine , and with a 390 stroker kit and a modified holley 2bbl carb and painted aluminium parts how cant it not do a good 400 hp and 400 ft pounds of torque if its not stroked , as i read everywere the 2bbl carbs are bad for fuel once modifed , but if a lot of work is done in iron heads or aluminium heads with some intake work and street friendly compression ratio it can be a killer little engine no ?
