I have been doing a lot of research on which cam Im going to put in my new setup. I think I have come a conclusion and I wanted you guys opinion on the cam that I have picked and if there is a better cam for my setup.

My setup:

Explorer 302
GT-40P Heads
Polished swirled valves 1.84/1.54
Mild port job
Matched Crane cams springs and retainers - 44308-1
1.7 Cobra Roller Rockers
Powermax 2031 Cam - CRN-444225
Lift: 513/529
Duration: 214/220
Explorer Intake
70mm TB and EGR Delete plate
Cold Air Kit

did you take into account that the cams lift will be higher with the 1.7 rockers?

as the specs look now, i'd say you'd be doing alright with that bumpstick

MadMan@TheWheel

1.7 rockers will put you at over .600" of lift, you had better make sure you have the piston clearance for that, or it will be quickly made for you

Other than that I agree with My77 (write this moment down) it looks like you have put a lot of thought into your selections.

1.7 rockers will make it .545/.562.

MadMan@TheWheel

Okay, splitting hairs. .542/.562 is still an area of concern with spring and pistons, yes?

I would go with a cam that has more duration.

And just for the record, the Crane 2031's advertised lift is with 1.7 rockers.

For the record you are 100% correct, click the link and it will state that. Oops on my part. I was assuming an advertised with 1.6 ratio.

On this particular cam, probably so. I'm betting it won't work with 1.7s for multiple reasons. But generally speaking, cam timing has more to do with PTV clearance than lift. I just put a .550 lift on the intakecam into a stock shortblock. But it was a CI custom, so it was designed to work. Most OTS stuff won't work over ~.540.

Springs?....yes....Pistons?.....it will depend on the other missing information, other than the lift #'s.
