I would check with Brian Tooley and use whichever of his springs he recommends.

if you are putting a carb intake on it, put a carb cam in it by calling a couple places and get something spec for your build rather than an off the shelf max effort cam meant for plastic low profile intakes

what they said ^^^^ is probably what you should do, I built my motor around the t rex cam, its definitely not a daily driver cam, as it feels sluggish when you're just trying to take off on a green light while trying to sneak past a cop, but full throttle and keeping it above 3500rpm after shifts it feels pretty good,

I'd call Geoff at EPS and see what he says; he created that cam after all.

But, that can was made more on a "I bet you can't fit it in a 346" whim... There's much better cams out there, and he'll even tell you that.

EPS makes an "off the shelf" single plane intake cam. I'd look into that as an option over the T-Rex.

T-Rex has IMO much too late of an intake valve close event for a carb style intake unless you want to turn it to the moon quite literally.

With a 6000rpm stall it would run it's cojones off though...
