Considering 3400 swap (not DOHC) into my 88GT 5-speed, need advice (Page 2/2) phils88GT FEB 18, 04:25 PM Ok, awesome. So this is all very good information. I needed and probably will continue to need to ask for advice on this. This is my first GM vehicle I have ever personally owned. I loved the Fiero GT when I was a kid, and now that I have my first one, I want to make it unique, my very own. I have been a Ford guy (Mustang) all my life, so this is quite a change for me. Cannot wait to dive in!!
