Chrysler 360 w/ W2 Econo Heads, Headers, 30.over

If you had any idea what I dumped into this engine you would know I'm not spending more on it, or tweaking it right now. My hope is to just tune the carb or replace it. I notice the Street Avenger comes with Metering blocks where the the HP 4150 does not, this should help me tune it. Not to mention all the other pieces that you mentioned. And thank you for the input about the curve tuning. All the other things you mention are too advanced for me and I haven't met anybody in the East Bay (near SF) yet to hang out with and talk cars and tool around. So, far I think I'm going to look into the Steet Avenger and see how she drives. The HP 4150 is so High with the Vacumn adapter plate I can't use my original 340 air cleaner :( and had to use the Edelbrock Pro Flo instead...maybe with the Street Avenger I can use it again! Thanks all.
