I am looking for help in selecting a camshaft for my engine. I’m looking to greatly improve the gas mileage which now is between 6-9 MPG, also looking for better streetability.

The engine is made up of the following:

1969 351W block bored .030 over with TRW forged 2378 +.030 pistons.

Ford Motor Sports GT-40 “Turbo-Swirl” Aluminum heads with 1.94 intake valves with intake volume of 160cc and 1.54 exhaust valves with exhaust volume of 53cc. Ford Motor Sports 1.6 Roller Rockers.

Cam is Ford Motor Sports M-6250-A351 with these specs:
Intake events open 9° BTC, closed 47°ABC, Exhaust events 62° BBC, closed 4° ATC, Duration intake 296 or 236 degrees, exhaust 306 or 246 degrees, Lift lobe .325 I or .336 E, Valve .520 I or .538 E, Lobe center 108°, exhaust 119°.
Cam intake and exhaust events are measured at 0.050 tappet lift.

Intake Manifold is Edelbrock Performer RPM. Carb is Holley 750 double pumper with mechanical secondaries.
Carb is in a fully sealed Paxton enclosure and boosted with a Paxton SN2000 6-8 lb supercharger.
Exhaust is custom 1-5/8” headers for Cobra replica.

C5 transmission with 2500 stall convertor and manual valve body.

Any help will be greatly appreciated.
