That cam went 10.80's in the 60 over 440 with the same top end with 12.5:1... Its a race only setup but would idle nice at 1800 rpm... 1 less compression point and 50 more cubes with a 1/2" more stroke.... I guess we'll see...
I'm going 11.70's with my 440 on street tires, pump swill, mufflers. It's got more in it. It idles real mild and can sit in traffic etc. If I want to go high 10's I'll do it on a light shot of NOS and maybe these new heads, no cam.
This stroker motor, if I do it needs to be a whole other level like low 10's on the engine, 9's on the bottle.
