you are a lucky dawg with the ported mn47 head, mine is a plain jane unmodded head with a stock cam. so yours should be screamer.
about the pistons you should cut them 2.5-2.6 mm of the tops and you should have a positive 0.2 mm deck height (at least mine did).
Now for the power figures -- I am planning to go to the dyno sometime next week. I am still breaking in the motor -- about 700 miles on it. About 25-30 percent increase in power compared with stock engine. -- It pulls as hard in ffth gear (0.75) as it did in fourth (1.0)
The 1/4 mile times cannot tell you because our drag strip (1/8th mile) is closed until next week. So next week is the measuring day.

awesome
about 2.5mm is what i was looking at
are you FI or carbs - hows that comp ratio working out for you - you running 91 octane? whats your timming at?
ya i cant wait to get it together - if i can get a good cam in there and some good ignition - im hoping for low 13s but im not sure what it will run
slapping it in the 70 with an early 5spd 10.5lb flywheel tripple 40s and 3.54s out back
70 yay!

A:
low 13s is pushing it, but it can be done
I am running the SUs on 91 octane and 2 deg BTDC on the initial timing (needing a race gas) but the compression ratio is fuUUUUN
Thirteens are possible, but I don't know if you can manage the low thirteens, but a good ported and polished head with triples can make it possible.
For me the next step is Megasquirt

A:
i think i can make it with good gas some timming a good cam the triples and ignition if i can hold traction
im sure that 2 degrees is hurting some i bet it would be a blast if you could get it to 10 - 15
where you from anyway?
