Stroker vs Stock Displacement

[JaredWOT]

Will a cammed stroker reduce gas mileage more than a cammed motor of stock displacement with equal grade cams?

all variables being the same...it shouldn't BUT you have a lot of variables to control.

Thank you! That is what I'm asking. Assuming all variables, spark, timing, AF ratio are the same, that a cammed stroker would still be daily driver friendly. It seems like with more air, a larger cam would be needed for the stroker, but I didn't know if a larger cam ALWAYS means more fuel burned. I would like to go with a forged 302 stroker kit and get custom grind cams, but not if it means my daily driver will get 10mpg around the city.
I am about to swap a t56 into the Mach though, so that should help slightly.

More displacement and longer duration cam means more air which will require more fuel. If no more fuel is added then the mixture would be lean. The difference between 281 and 302 shouldn't be much, though.

Any idea what a ballpark figure would be for combined mpg with a cammed 302 stroker paired with a t56 using 4.10 gears? Comp cams 106100's are about the aggression level I'm shooting for.
I want to go stroker because of the added power, but also because of the benefit of having more power lower in the rpm's. The car will have a p&p 10" short runner on it. I know that plus cams shifts power upward and helps it wind out farther, but that generally detracts from the low end as well.

IMO, i think it more so comes down to the tune. my car is a stock stroke 284 that makes about 400rw and i see probably about 200 a tank lately..Hasnt seen to get worse since being tuned on the 39lb injectors but i also do not daily my car.
I thought id want a stroker super bad for the torque and easy ability to make power, but Compression also allows the motor to make good power! One day ill have a BB stroker setup though

I thank you for that! It looks like it depends on he cam and tune that goes along with it. You have a pretty hefty cam in there too! I see that your cobra has the exact suspension I'm looking at, besides the IRS part. Can you tell me, so you consider the cost of the MM coilovers, tubular a-arms, tubular k-member, and the Koni SA Yellows to be worth the cost even if it's mostly a street car that might only see 3-4 1/4 mile passes a year?
