want to build a blown 489 stroker

Hi guys,
I want to build a bbc blower engine for my 66 chevelle, it wont ever be raced so i guess im looking for an engine that can be driven daily and be reasonably reliable for street and show.
I have the opportunity of buying a friends stroked 489 BBC engine at a good price and am hoping you all can give me some advice on what i will have to change in the engine to build a good Blower Motor ( ie dished pistons and blower cut cam, or anything else ? Like maybe an 871 vrs 671 ) part numbers would be awsome !
The 489 stroker info i have is as follows
currently it has around 750 HP it is a 91 GM 454 4 bolt mail block
13-1 30 over forged JE pistons
Eagle H Beam Rods
Eagle forged stroker crank
AFR 2101 325 cc aluminum heads w/1.7 crank rockers 13750-16
AFR stud girdle
Isky 396686 cam, 202-96 rh lifters, 9265 valve springs
2902 Edelbrock intake
Holly 1000hp carb w/barry grant regulator
B&M flex plate
Powerbond 6" ballancer
MSD 84891 crab style distibutor
with a 7 qt kick out oilpan
I could really use some expertise in what i would need to change to have a reliable Blower engine. pistons, cam, are the heads blower friendly ?
Any help with this new build would be greatly appreciated.
