IVE always prefered solid flat tappet lifters as they are a bit less likely to get into valve float issues at reasonable rpm limits ,(naturally you need matched springs and carefully checked clearances) and the cost of components is much lower than with a roller valve train, on a 383 thats generally about the same 6200rpm-6400rpm band so I prefer the solid lifters, naturally your compression ratio and drive train need to match the cam sellected, and Id point out that most solid lifter flat tappet cams are a bit more aggressive than your average hydraulic cam for street use.
one combo Ive used alot,with good success, in camaros and novas, etc, is a crane 114681 cam (generally installed retarded 4 degrees) http://www.cranecams.com/?show=browsePa ... vl=2&prt=5
matched up in a 10.5:1 cpr 383 with a dual plane intake , like the Weiand 8501 or EDELBROCK RPM AIR GAP, and either a manual transmission or a 3000rpm stall converter, decent heads like the brodix -8s , the 200cc brodix IKs the AFR 195cc or 210CC or even the DART 200cc heads, a set of roller rockers, and youll want a 3.73:1-4.56:1 rear gear depending on the car weight and decent headers, but it tends to make decent hp/tq at a low cost, not necessarily ideal for long trips and great mileage but it will put a smile on your face when your accellerator pedals firmly on the floor
depending on the combo your easily over 400hp and with a impressive tq curve in the rpm range you can use on the street!
