Hey guys. Looking for some input on upgrading my stock 305 TPI in a 1988 IROC. The car is all original and in beautiful shape. I want to basically keep it as a "stock" car but am looking for some minor performance boosters. Emmissions is not an issue due to a classic registration. Any thoughts on some relatively easy upgrades? Also was looking into installing headers, but seems like these could be a real bear to fit in. Any thought/experiance with this? Thanks for any input!
