Well, i plan on building a very streetable road warrior. No drag car, just a bad-ass 440+4. Something that starts up and drives good, but can still hold its own on the track or a street course. Will these work??? I only paid 200 (all mopar performance and in the package!) for these and an aluminum water housing+pump, E body resonators, Double timing chain, Valley pan, windage tray, HP oil pump, full BB gasket set, push rods, springs, lifters, valve covers, and more that i cant remember right now.
