If so, scan the Dyno sheet and post it.
Based on the MPH your down of H.P.

When I ran my '74 Corvette I/SA car back in the '90's one of the things I learned with my engine was that the car was much quicker when:
1. Held the car at the line @ 1,500 RPM
2. Flat footed it on the last yellow
3. Made the 1st to 2nd shift @ 5,100 RPM
4. Made the 2nd to 3rd shift @ 5,500 RPM

When I made the switch from a Turbo 350 to a Turbo 200 my car picked up .20-.25

Back then my engine was just a home built adventure and only made 378 HP. It ran ok, but would not come close to running with the guys that had there packages all iron out.
At that time, a good friend and customer, Jeff Stealy (Rest in Peace) was a First Class Stock and Super Stock Engine builder. His engines of my combination which was a 350 with 882 heads,were making 420+ HP.

Other things to look at are brake drag.... you should explore everything, front to back, and make the car roll (push) with as little effort as possible.

Interesting !!
My M/SA 1969 Impala ran a 350/255 with a Turbo and 3800 Stall Conveter.
Shift points were near identical.
Used 5.13s and 28 inch tire.
Woodro Built the Engine
Ran a best of 12.80 in WPB, Florida weather.
Before Woodro ran barely on to 3 tenths over the Index, mostly hot weather.

Always wondered how it would have done on a cold day?
