Hey... I am pretty darned active.

350 will fit, but will need the radiator support modified to move the radiator, and condensor foward.

I kinda wish I would have gone ahead with the 350 vortec motor, 4l60E...:)

Trust me.. We are all very aware of SBC/BBC 90 degree interchange, and have done the research necessary to decide the best option for us. We are kinda an "outlaw" group here though. Not blinded by total brand loyalty.... just do what we feel to make our trucks "better"

4.3 TBI is a modest 200 HP, and 250 ftlbs. I think thats adequate for a raider. BUT.......... Put 35's on there, bigger axles.... and you start having thoughts of 5.7 Vortec motors.

109 Hp upped to 200 or so HP. Imporoved Gearing, Strength upgrades. grunt grunt grunt.
