My current set up is, 440 .03 over Straightline performance hydraulic flat tappet cam 226/238 duration @.05 503 lift with adjustable hydraulic rockers, Edelbrock Performer RPM intake with a Edelbrock 650 AVS-2 carb. Pertronix 3 distributor. 4 speed with 3:54's. This winter I plan on going with a Scott Brown Hydraulic Roller setup and possibly a new set of heads not sure who's heads right now. Not sure about the Eddie's as the plugs are set at a angle and if I decide to go with headers not all headers will clear the plugs. 440 source heads and Mopar Performance heads have straight in plugs like factory heads, I like the Mopar heads but are about $800 bucks more than the 440 source heads. I do know some guys running the Mopar Heads and they really like the improvement but I do have a budget and the way this country is heading who knows what's going to happen and might need my car fund for other things to survive LOL
