Instead of spending all the money on the stroker crank and block girdle huge heads etc.
That will need a ton of RPM parts and need to rev to the moon.
Why not use the stock block and crank and supercharge it. You need raw torque and power to get that heavy truck going. low cr 305 with a weiand 142 blower+750 holley/edelbrock. 400+++HP on pump gas.
stock low compression 305 short block.
ported stock heads, ported vortec heads, .....ported 083 head
ported camel back head) (1.94x 1.50)
ported 113 corvette l-98 aluminum or equal or a better aluminum head.
big power at moderate boost on pump gas. bigger power on race gasor water injection wiith agressive 10-14psi boost from a weiand 142 blown 305. Big visuals on your truck.
twice the power and torque gain for the money spent.
1/4 the complexity and hassle.
305 blown with a larger 177 weiand is another path. Even more power and visuals.
Nothing grabs the eye like a Roots Supercharger. Turns as small CID motor into a much larger motor.
