I am thinking about purchasing Eldebrock runners are they good and worth the buy... I have the eldebrock intake already...are the gains considerable on a 305 TPI??

on a 305 with little mods, id spend the money on something else first.

well if he has the runners first, then those "other things" will be even more beneficial at the time of their purchase, just a thought

 

true, all the mods will pretty much play off each other, kinda like how a K&N on a stock engine is almost useless, but will make alot more power compared to paper filter on a supercharged engine. iv just heard people loosing HP and TQ using new runners with little or no other mods,

Don't get runners first. Your stock ones were designed for a 305, and Im sure they are good for at least 100+ horsepower over stock. If you haven't gotten new exhaust yet, that would be a better idea.

 

I've got 3 inch cat back dynomax system on it!

HEADERS, HEADERS, HEADERS & new cat. Maybe a chip/tuning. Forget the intake side until you're in the 13s with that 305.
