Dyno a 7.5:1 400? Sure, why not?

My wife drives a '74 four door newport that we've had for 20 plus years and just for sh*ts and giggles I put on a performer intake, carter 600 afb, performer plus cam, mp distributor, a cloyes double roller timing chain ( just in time too, one tooth broke off and multiple cracks on the cheap stock one ) and a dynomax turbo muffler so it could pass slow traffic easier and you could really feel the extra power, you should hear her pulling out of the driveway, BAWWWWAAAAAA. I stopped there so it still has the stock manifolds and single exhaust, now I'm gonna put on a 750 holley and dual x pipe exhaust, all things just lying around anyway, she'll love it. She will want a bigger cam and headers next.
