I have a 79 Lil Red Express truck with a 408 Magnum stroker in it. The specs on the engine are 10.5.1 compression, Edelbrock ported heads, Hughes Hydraulic Roller (Custom Grind); 228/236 @ .050 .550/.565 on a 108 LSA w/ degrees of advance and Crower 1.7 rockers. Has about a 2500 stall in it now along with 3.55 gears. Currently has an Edelbrock Performer RPM Air Gap with a Holley 770 Street Avenger. My brain was wondering with this combination if the Mopar M1 4bbl intake with a rebuilt 850cfm Thermoquad if it would be a better runner in the mid range and up top? Just something I was throwing around in my head at this point.
