Jack46,
I haven't even thought of how I want to configure the fuel system. I guess I need to start thinking about that along with everything else. Right now I'm just starting the short block; dropped it off at the machine shop last week. I've already got the Q45 rear and 2 sets of halfshafts. I can't imagine putting in a 9"; even though it will get mostly street and drag use, for my needs the car must remain IRS in case I take it to an autocross or road course for a track day.
As far as headers, I know someone who makes custom headers as a hobby. I plan to get him to make a set for me once the car is done. With all the research I've done and all the posts on this site about crappy block hugger headers and long tubes scraping the ground I think a good fabricated set of step headers is the way to go with a psi motor.
Later
