Im building a 472 hemi engine for a 65 A990 race hemi car. It probably will never be raced.It will mainly be used for show. It has a A&A cross ram , 770cfm holleys,11:1 comp, mp alum heads(non ported) auto with 4.88 gears. Was thinking of a solid mech roller cam , around 650-700 lift with 300+dur......im just looking for a big crackle.....How would you guys do it ???

Btw.... its a good cat 4.25 water block with a ohio crank rotating assembly.
