I have a 1981 coupe with 19,871 original miles on it and would like to increase the engine performance without changing the outward orignal apperance of the car any ideas, tips, products etc would be greatly appreciated.
There are a number of things you can do to your L81. Jack has given you a very good place to start. Check it out then if you have more questions please ask. I would also like to invite you to check out the L81VetteRegistry .. A website for 1981 Corvettes
I hope you find the rest of the Corvette Action Center ie. Spec pages, tech, parts sales and on and on. You see the Forum is just the TIP of the Iceberg.. so to say :J
Thanks for coming aboard,, enjoy the ride :W:
