Got my exhaust back on now. It dont seem to be much different yet. Since I put the cat back on I pulled the negative cable so the computer would reset so it could reprogram witht he cat being on. Now I wanna seafoam this thing. Can you get seafoam at advance auto? Oh and wouldnt it just be easier to put the can of SF into the gas tank?

Well I got a cat, Just gotta get it put on there. I got the cat with the o2 mounted in the pipe also. Ima put it back on and use my Thrush turbo and run me a side pipe again I guess. I had the best power that way. Still urkes me that I cant turn the tires over on dry pavement. I will update when I get the exhaust back on and test some. Also I replaced my T-stat and it runs about 190-195 like normal now. I checked my throttle body and it was pretty dirty. What would it do if I sanded it really smooth and polished it? Help any? I will get around to making a CAI with a heat shield soon.
I also modded my front bumper and installed some lights. I will get some pics up soon.

Hmm. that gives me an idea. If I ever have an engine thats on its deathbed I'll just put steel dust from all the grinding I do straight into the intake!

just a heads up the little filter on the valve cover should have a fitting on it and be hook up to the tube to remove crankcase pressure at higway speed

and i know, but i kept replacing the hose grommit and it kept breaking from the heat so i said screw it and now instead of getting a puddle of oil in my intake, i get a puddle of oil on my polished valve cover.

and that is my breather that would go into the stock air box (which is obviously gone), the pcv valve is on the back of the valve cover, you can just barely make it out in the second picture
as for my exhaust i have parts store pieced together straight pipes, because for some reason they won't carry pipes longer that a foot long. i'll get a pic up of them in a bit.
