Nick if you click the link in my sig it will take to my page on the 62 to 65 Mopar site. Near the top it has my first 906 headed 440 build that ended up running a best of 11.49 @ 116. A bit farther down is my 493 build that has run a best of 10.70's @ almost 125. Both are pump gas street builds I drive everywhere. Don't know if it will help you but you may want to look at it. My old 440 build used the MP solid flat tappet .557 cam and my 493 uses a Dwayne Porter solid flat tappet cam that's 264 & 270 @ .050 with .585 & .592 lift with a 110 LSA. It has a little rump rump but the car idles nicely and of course I am an old hot rodder who loves a little rump rump in my hot rods idle. Ron
