I am looking at putting in a LQ4 or LQ9 in a '85 C10 swb. backed by a 4L80 trans. I have a goal to be somewhere around 350-400rwhp. I was wondering if the 243 heads and G5x3 cam will get me in the correct direction, open to suggestions thanks

 

Setup with a 90mm tb and manifold, with a good exhaust and intake setup, you should reach that easily.

 

What intake do you recommend? and tb? there are long tubes available that can fit into my pickup nice. the truck is dbc and im prepared to go dbw to make it easier to connect cruise control.
