360 small block (big power)

I just put together a 410 stroker [360 +.040]
I bought the kit through Ohio Crankshaft for $950 internal balance/tax+$1340
This is what the kit consisted of....

Scat nodular crank
H-beams bushed w/ARP 2000
KB 356 hypers 498grams= 9.8 set up at .039 clearance to head.
Speed Pro moly rings
Speed pro main bearings
Clevite rod bearings for radius journal
Internally balanced assembly

The cam I'm using is an Engle KV-3 [custom] I had it changed a lil to .573 252* @ .050 284*adv dur 110cl
I'm using 915 j heads [was gonna use 974 74-75' heads but a friend gave me the j's witch already had seats put in the int & exh]
The j's are pretty well ported [no more roof hump at all, no more push rod pinch, long profiled guide, and cut down the bulged floor on the straight of the short side which was then lay'd back with the rest].
I have dropped these at PROAIR to be flowed [we expect 260-270cfm] but we'll find out when there done[maybe I'll post pics]

This all going into a 3192lb 4psd 3.73 geared valiant.
I was going to just throw on the set of x heads from my 340 that are 'mildly ported', in comparison to the j's, that flow 242-185cfm which is plenty enough for 498hp.
The carb is a proform 850 main body with billet throttle plate and billet metering block kit [It's cheaper then buying a complete carb]
And don't buy the regular 850 dp for a radical cam engine the calibration is lean in most cases, if you do you'll end up with aftrmrt metering blks & main bdy w/adj air bleeds to be right.
