Hi everyone,
I have been looking for a 1987-1993 5.0 GT for a while and finally have a few lined up that I think will work out. The one I am really interested in is bone stock other than a K&N filter, advanced timing and a Flowmaster exhaust. The other has E303 cam Edelbrock Performer Intake, and Aluminum trick flow heads (possibly more that isn't listed, I have heard depending on how far you go with upgrades you have to upgrade your injectors and MAF and stuff).
I have never cared about gas mileage for performance/fun cars before but I am planing to use it as a daily driver for the summer months so for once gas mileage is somewhat of a concern. Luckily for me my total drive time per day is usually around 30-40 minutes so I don't need a car that is great on gas mileage, I just don't want to end up stopping at the gas station daily either.
My question for the experts here is, does anyone know what impact the above modifications would have on gas mileage? The manufacturer mileage said the car should get about 18MPG city and 23 MPG highway. Using that as a baseline however true it is or isn't, should I expect something like 16MPG/21MPG or something more drastic like 8MPG/13MPG (likely a huge exaggeration.... hopefully, lol). I have heard in some cases timing and a few intake/exhaust mods can actually increase mileage but I doubt this is one of those cases.
Thanks for any tips or information you may have.
Adam.
