I had thought about going from my current 47# flywheel to the 30# steel, but I understand the Weber ones don't warp with street use like the Mopar Performance ones. The larger lifter makes a big difference in flat tappet cams. Chevy is.842", Ford is .875" and Mopar is .904". I think the siamese runners hurt the Chevy and Mopar heads. Using rocker shafts makes more sense to me also as it should have better control over the valvetrain gometry. The biggest factor in my first Mopar engine for the Cobra was $1300 for 406 horse. It helps to have connections.
