Ok the 340 is done for the challenger Now My brother is working on getting this other 340 built for his 72 charger,and Kinda looking for ideas for a cam etc, thinking solid roller? It will be a 416 with a eagle crank, eagle rods, J.E Pistons for a 10.1 comp with edelbrock heads, Probably just stock as their bought?, A Rpm Air gap Intake, or a single plane? 770 avenger? Headers,3:91 sure grip,auto with probably 10" 3500-3800 stall? Would still be steet driven, as well as taken to the local drag strip too. Welcome any and all Ideas!
