All:
I finally decided to take my car to a tuner and get it dyno'd. I have a fitech and was able to get it 85-90% there but had some driveability issues that I wanted to get resolved. I went to Church Auto Tune in Long Beach CA as they came recommended as good with EFI systems. I was there for 3 hours on Saturday and the results after burning 1/2 tank of gas on just dyno pulls came to:
181.22 RWHP@5300 RPM
206.49 RWTQ@4000 RPM
If you apply the 15% drive line losses estimate, the engine is making in line with some of the other engines of similar spec out there. All in all, it was money well-spent. It drives so much nicer and pulls strongly from 2k on up. I played it conservative on the RPM limit, so next time I may go to 6k or just past.
For those wondering what the setup is:
Engine/Transmission
• 1982 200 Block
• .40 over with flat top pistons
• Stock 1965 rods/crank
• 10:1 compression
• Classic Inlines aluminum head
• Classic Inlines 4 barrel intake
• Fitech Go Street fuel injection
• Clay Smith 264/274 cam
• 6 into 1 header with 2.5” exhaust
