I have a 355 rotating assembly freshly rebuilt out of an 84 Chevy truck sittin in my shop. I originally rebuilt it fora different project but scrapped that project, now I just have it. I've been thinkin about an engine upgrade for the burban, and god only knows how much I want a full roller BBC, but I just cant afford the $8k to build the engine of my dreams. I was thinking, if I could put a set of Vortec heads on my 84 rotating assembly, then throw on all the TBI stuff up top, would it work? What I want is as follows 4 bolt main (my block does have that) 383 (decided to go with 355 since I have it) Vortec heads (We have a 97 Z71 so if I can convince mom it needs a new long block... /forums/images/graemlins/whistling.gif) Edelbrock intake Turbo City TBI unit (great writeup on them in Chevy High Perfomance) Good bumpstick Tri-Y headers & true duel exhaust Open element air filter Milodon 7 qt. oil pan I'm hoping all this will net me at least 350 HP and 400+ Tq. So, will it all work together?
