I was just curious how big of a difference I would see in performance from my 305 if I put in a hotter coil or rebuilt my HEI with a kit and upgraded the sparkplugs?
I've often wondered if any of the lost throttle response I've suffered is caused by lack of proper spark. I'm certain the coil is the original; I know the distributor is. I have no other mods, and I run my truck on Chevron 93 octane.
Also I've been thinking of upgrading the intake and carb. My truck has got all of the emissions @#%$ on it with the 4bbl Rochester, and I was curious if the Edelbrock Performer will help throttle response with the stock Q-jet. If not, what's a good carb?
Thanks for your help.
