mind you my dyno reads a tad lower then your average dynojet, regardless of numbers this car runs hard, it has gone 6.45 @ 109 mph in the 1/8th @ 2000+DA on the Base break-in tune

DAYUM! 600+ NA! Well done!

Wow!! Nice combo. I bet it has amazing street manners for a car with a big cam like this. Great work.

Does it run on 91 octane?

0Cunningham Motorsports

Yes it can but this build was never intended to run on 91... For this motor to run on 91 alot of power will be sacrificed ... For a pump gas motor I would something with 11.1-11.5:1 compression
