Hey my name is Chris i am from Mesquite, Tx and in a car club Freaks of Nature. I just picked up a 5.3L for my 85 s10 xcab bagged and bodydropped on 20s. Picked up motor for $150. It has just about everything minus cam and front parts. It has Intake, throttle body, injectors, fuel rail, 702 heads, rods, pistons, oil pan, and few other parts. What i am wondering is can i bore it out to a 6.0? If so will it be to much? If i leave it a 5.3 what are the upgrades that i can do that is cheap and will get me to 400rwhp and 370lb-torque? Is a 4l60e or a 4l80e better? I have a friend that will sell me a 4l80e (i think its an 4l80e) for $200 i kno its a good deal. Please let me know what u think.
