89 305 needs power
I have a Stock 89 RS with a 305 and am looking for a good mid range power upgrade. Can someone please let me know the best every day power upgrades they have found for a TBI set up. I already have a Holly intake with ported and polished throttle body. Looking for the best match on Heads, Cam and exhaust set up to get all I can out of the stock 305 with bolt on upgrades.
