I'm REALLY interested in installing a turbo OR supercharger in my '70 Nova, but my current 454 is a 12.5:1, solid cam motor which I'd prefer not to disassemble. A friend has a nearly stock 454 which I can get for a good deal. My question is, considering the following configuration how much boost will this combo safely handle? I'd replace the oval port heads, intake/carb and cam, but the short block will be left alone. My main concern is the presence of a lot of cast parts and a 2-bolt main. I'd like to end up with a combo that'll make 500-600 boosted horsepower (on a budget of course).
454 w/.030 overbore (balanced and bluprinted)
Cast crank with standard mains and rods
Cast pistons w/8.0-1 compression (NOT forged)
Two bolt mains
Stock iron oval port heads (to be replaced - best options??)
Old, old aluminum intake for weight savings only (to be replaced - best options??)
Crane 266 hydraulic flat tappet cam (to be replaced - best options??)
Roller tip rockers
Stock 6 quart oil pan
63K miles since overhaul (I'll probably change the bearings)
Thanks,
Dan
