6 cyl a230 ?s

budget is factor get a magnum 318 and add a 4 speed a833 you can reuse pedals but not the torque shaft/bellcrank. and you need a new bell housing for the small block. Drive shaft is the same tunnel will need to be opened up not hard to do and add a floor hump a833 has its own shifter linkages and shifter.

i have a four speed with a 318 magnum rpm air gap stock cam this motor frys the tires alot of torque and the motor was used with 150,00 miles
