82 Carb conversion
So the "emissions" check fellas out here are'nt the brightest, so I am not so worried about failing. I could easily put on an earlier air cleaner and pass the test. I have my eye on a very nice 82. Could I not just convert to a carb set up along with my plans for heads and cam? Been over on the missfire sight and they focus mainly on improving what is there. Why not forgo that injection and put on a carb/heads/cam combo (yes, of course, with upgraded exhaust)?

I want to get to at least 300 bhp and with a good cam, some nice higher compression heads and the right intake set up, I know I can EASILY do it. I was just wondering if there were folks how have converted their Crossfire cars to carbeurated set ups? I make over 300 (at the motor) all day with my '96 Impala SS LT1 on just a cam complimented with tri-y's. The car is stupid fun and runs 14's. The how too's on making the power is not an issue for me. I have seen some good examples of header's I like (some tri-y's even) and some nice dual exhaust set ups for these cars. I am sure (as with any engine) the Crossfire will respond to all the basics, but it seems to have it's limitations on up to the higher power figures. I would not mind seeing mid-low 13's on the car. I just can't have a 4dr machine that out weights AND out runs a vette. I know I could find an earlier machine...but the '82 I am looking at is VERY nice and way under priced.

My 4L60E in my '96 Impala did not like anymore power than stock either 
At least I know that the carb conversion (realisticly, you can throw a carb on anything) has been done and I am not crazy. I'd figure on making it LOOK like an 80 or 81 under the hood. Insane power can come later, I have no interest in killing a tranny/rear diff. Built motors go hand in hand with stronger driveline. I am sure to start with a mild cam, intake, carb, headers and exhaust all at once. I would preserve the injection pieces for value retention purposes...the car is a very well restored/correct car. Now my thoughts lean towards the fuel system itself... I wonder what pressure that fuel pump in that car operates at and what dictates tranny kick down (is it mechanical?). I'd start with the exhaust, see what that gets me and go from there. I can't imagine how terrible the flow is through the catalytic converter is on the wheezer pipe under the car.

This is making me more comfortable about getting my hands dirty with this car. This is the info I need. I'll keep you in mind on the HEI. I have been using the MSD billet distributor for all my carbeurated applications, those things are stupid easy to tune. Initial, total, advance rate, and vac advance are all done on the unit. No messing with turning the distributor body to tweek the timing. And setting total advance is a breeze. So I've have a running list now of things to keep in mind: Fuel delivery, tranny kick down, HEI unit... what else?
