Pertronix HEI tune-up kit? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

My truck is almost due for a tune-up, and i was thinking of hopping up the ignition system a little bit. Right now, i have a 350 motor, and a stock HEI distributor. I was looking at a Pertronix HEI tune-up kit in Jegs. http://www.jegs.com/cgi-bin/ncommerc...33&prmenbr=361
Would the kit give me any more power, or gas mileage, over my stock HEI? My engine makes about 300HP, but i never really go above 4500 rpm. Also, i was planning on using regular ACDelco spark plugs when i do the tuneup. Is there a better plug for me to use? I used to run Splitfire's in my EFI S10, but i have heard that Splitfires don't do very well in a carberated engine.
