I need some advice on a stage II project i'm working on. First of all it's a late 153 block With 3.875 bore and 3.4 stroke. Wiseco 8 to 1 pistons , 6.5" crower rods, milodon gear drive , reed solid roller cam ,stage II heads, on center. The engine was built to be B&M blown and injected. I want to run mid to hi 9's in a 3500 lb car. It will be a street strip application.
1. What cam to run? The cam in the engine is a Reed solid roller 250 250 duration at .050 >634 lift 112 lobe centers. Sounds like alot of cam to me.
2. To port or not to port the heads? They are aluminum stage II's
Should i have them ported or just knock the boogers out of the ports. These are new castings that have never been assembled. The ports are huge.
3. With only a 3.875 bore will the 2.02 - 1.60 valves be a problem?
4. Turbo ? I'm thinking 72 - 76 . Will it be enough?I don't want to go overboard so i can keep it streetable.
5. Intake? Will there be much power difference between a converted carbed intake and a sheet metal piece?
6.Stall speed? I'm thinkin with a 72-76 turbo about 3600 -3800.
Any and all advice would be appreciated. Thanks Steve
