i have a 416 dynoed at 624 with a solid cam and eddy heads 12.5 compresson

I have a 414 that's capable of 600, but I'm trying to keep it down to 500 because it has a cast crank. With a forged crank, I could push it to 600+ with a bigger cam and different intake and carb.

 

[rumblefish360]

If ya can find some used W-2 heads... I'd go there and a nice solid cam.

As far as kit goes... no.
What I would look for in parts would be fordged crank, slugs and new rods of your choice, of course something beefy!

~ .040 over 360
~ Cast MP 4.00" crank
~ Eagle H-Beam 6.123" rods
~ Milodon 4-bolt steel main caps
~ Diamond Racing Pistons dished forged pistons
~ Total Seal's gapless top rings
~ Mopar Performance W-5 cylinder heads w/ 2.05-inch intake and 1.60-inch exhaust valves.
~ Mopar Performance's excellent W-5 tunnel ram manifold w/ twin 750 cfm Demon TR carbs
~ TTI's W5 1 7/8" headers
~ Crane 260/268 duration, and 0.420-inch lobe lift roller cam (this cam is very stable and easy on the valvetrain, and does not require
outrageous spring loads, and supplies the area under the curve)
~ Erson rocker kit (comes complete, assembled with rockers, shafts, spacers, and hold-downs)
~ oiling mods installing a bypass in the upper oil galleys, and rerouting oil to the #1 main
~ Speed-Pro's Competition Series bearings throughout
~ should get you....

Here's a link to a pump gas 440cid I just did. I would prefer to go 4.25 crank and 4.125 bore though...that's just the way it came to me:http://board.moparts.org/ubbthreads/showflat.php?Cat=0&Number=5529974&page=0&fpart=1&vc=1

yah everybody likes to see BIG cc#'s when it comes to port size. what they dont realize is that they need 7000++rpm
before those port sizes become an advantage. good read thanks. and excellent job too.

I'd be looking for an R3 block.

 

[chrisw21_2000]

big ports kill velocity. Want horse power get big short runner heads and turn high rpms. Want torque and throttle response, small long runners.

Best Machine can build you a "nice" small block [big inch] Call them for a price quote! or check w/them on line! Chuck or Pete!

yes big ports kill velocity, but that CID/stroke/rod ratio dependant... your port analogy is like comparing a
Top Fuel Dragster to a Tow Truck lol.

Need a lot more info. How much will you spend? What are you doing with it? Why 600hp?
