Headache is right. A little after posting this I bolted up my freshly ported early model blower nice pear shape outlet trimmed up inlet with coated rotors and a 10% pulley and mashed the pedal on quiet side street...boy was that fun for about 10 seconds. I developed a slight misfire and saw the magic white smoke that makes your car run exiting my tail pipes by the time I got back to my driveway. I knew full well this was not only possible but likely and i had no business doing it but you see... I have a condition. I have to learn things the hard way. The car was running fine but I had to beat on it. At least I now have an excuse to finish porting my spare heads...(see condition above). I did think for a second a donor 5.0 wouldn't be bad with a 5spd and 3:55 already in the car. And should be smog legal if done right but that's out of my budget which is zero right now. That's supercoupin'
