i have a 79 350 turbo 400 in a 91 s10 and i want more top end power out of my stock setup. Now i do have a set of vortec heads edelbroc intake and a new carb. now is this going to be good enough to improve my top end or do i need to add a cam to the equation and if i need a cam do i need to replace the stock springs and lifters. this is my first build and i am doing it by myself so anything u guys could add to help me out would be really awesome. like i said i am pretty impressed with my 0 to 60 it is a sreaming little truck stoplight to stoplight but i want more!
