I did a conversion on a Corvette engine L98 so it could burn 87 octane. As an unexpected result I arrived at around 34 miles to gallon on my first gallon. That was on a V8 and I do have a photo to prove it as it got that consistently. Stopping at lights and getting through about a half hour drive each way to the store. All I did was install a .30 of an inch gasket in a head rebuild. That lowered the compression so I could avoid the pre-combustion or detonation. Then I increased air flow but understand the corvette is more tunnel like.
I liked the result.
I had some other mods and would like to share some time. I have been kinda busy and it will take a while to test the tank on this 4 cyl.
If the distributor is not set it can really glow the exhaust but I am not doing that this is a cheap easy and fool proof. I think is sounds a little smoother running right now but I know that is a lot to assume at this point from a simple mod.
