If this motor has a dished piston or a flat top piston and (72cc heads) and the Deck clearance was not dialed in
("0 deck") then the cr will be modest.
What piston? what installed TDC piston deck clearance?
If you want 500hp you can get it but you will have to change things.
The cam is not serious enough. The converter and gears are not serious enough if you are going drag racing.
But you need a performance baseline to verify your hunch on this cars performance.
(a day at the drags to get some time slips..."test and tune" on sticky tires)
I see a 110-112 MPH (1/4 mile) car here.
Assuming correct tune up/setup.
When ever dealing with a combo that is not performing to expectation:
Always start with doing a basic engine cranking compression test first to verify general engine health. FIRST
DId I mention EXHAUST SYSTEM and fuel system
