MP 509 cam

I ran that cam in my Eddie-headed 367 streeter @ about 11.3Scr.It was a wild ride when it came on, and it pulled to well past what I wanted to rev to. But with a stick car the bottom was, um, terrible. Without a TC, it wanted a lot of starter gear, or a lot of clutch. With 3.55s and a 2.66 low, the power didn't start until nearly 40 mph. Well guess what, most of the time on a streeter, I spent driving at 35 or less. So that wasn't working for me.
4.30s brought it down to 35mph. Swapping to a 3.09 low tranny, brought it down to 30,Yipee! 4.88s brought it down to 27mph,Double Yipee! But now in normal driving mode, first gear was ridiculously low. And of course I had to buy an overdrive to hit the highway. But man that thing pulled. From about 5000 on, it was a terror.
It also gulped gas like a fish gulps water, and this was supposed to be a DD all summer.
Yeah, so the first passenger that nearly giggled himself wet, he liked it so much I sold it to him cheap; BaBam!!

If you run that cam, you will want to set your engine up ,to shift near 7000rpm, so you will need to do a few mods to your oiling system; or expect to lose rods,and/or crank. I shifted that bad-boy at up to 7200.Yeah;cast cranks go there. OR at least mine does;stock 360 crank and 340-type rods, with KB-107 lightweight hypers.
Oh yeah, a 3.31 stroker will be even softer out-of-the-gate.
But I guess this is the Racer's Forum, so none of this may apply to you,lol. I just wanted to let you know a little about this cam's personality. I don't miss it;at all.
