Greg - Dwayne didn't say. He actually recommended something a little bigger for max performance, but I talked him down in exchange for some better street manners! Mopwers - My goals and plans...well its a 72 Challenger all steel full interior street car with 4.10's, 295/65 drag radials, 3" exhaust, and 9 1/2" converter. I'm hoping for upper 10's, but I won't be legal anyhow (no cage). I need to make a decision on that one...As for why I chose solid Flat tappet vs solid roller. Mainly cost. Al - If this thing makes 700hp I will flip! Thanks for the positive vibes, man. Deaks - I get 10.5 w/82cc chambers. Pistons are a couple in the hole and gasket is .040

Guy I know stealth head setup but with more cubes and it made 610....
Early 70's 440 block (unsure of year) prepped for overhaul/rebuild. 440 source 543 balanced stroker kit: (.055 over) 4.375" bore 4.500" stroke Forged flat-top 2618 T-6 aluminum billet pistons. 4340 forged steel crankshaft 4340 steel rods, full floating .990" pins Clevite bearings Childs & Albert ductile iron plasma-moly file fit rings 440 source Stealth aluminum heads with full port job; 2.14/1.81" valves, 84 cc chamber size. Comp Cams (#953-16) valve springs Open: 456 @ 1.250" Spring Rate: 473 in/lb Coil Bind: 1.085 Cam Motion custom ground hydraulic roller cam: Lift: .540/.527 Duration: 240/245 @ .050 Lobe separation 110.2 Comp Cams: push rods, 10 degree super locks & retainers. Compression at 11.04:1 Hughes Engines 1.5 ratio cnc'd aluminum roller rockers, cryogenically treated. Hyd roller lifters. Milodon External oiling system with Melling HV oil pump. 440 Source 7 qt. aluminum oil pan 440 Source windage tray Carter HV mech fuel pump.

Well I took the 543 stroker to the engine dyno for a break-in and tune. It was awesome and I am still grinning! The results were quite good. I have about 8 pages of test results, but the bottom line is: 610 horsepower @ 5400 RPM with 651 ft/lbs of hole stompin' torque!

Your car headers will likely give more low end torque (below maybe 4500), but the larger dyno headers may give a touch more peak horsepower. (but they are likely too big for your application IMO) Too bad many car headers don't fit around the dyno.
I look forward to the results.

It's on the dyno and was getting all hooked up
sweet! thanks for dropping off the spring tool. I hope to see you tomorrow after work for the fun
WEDGIE - Very cool combo you have there. A real stump puller to the max! That thing must idle like a stocker with the mild cam and all those cubes. I like it

Yeah Paul PHJ426 bought the 508 and the heads that Chuck at Best Machine didfor me (see the tech Archives), but last I talked to him he bought a Primo Black 70 440 Cuda so I think he back-burnered the Road Runner Stroker project. Well when you get her running just get a hold of me and you can borrow my old ported SD,...the runners are around 3.25 sq in (about 15% bigger than the standard 906 window) so it's really too big to work with a standard Valley pan port, You'd have to cut the Gaskets special and seal the valley. I bet I could have pretty much filled a super big gulp cup with all the aluminum that came out of that thing. I'm trying to remember, your other motor was a low deck 4.25 crank, right? the one with the Stage VI's and the Indy dual-plane? btw....your 512 I think (if it's .030 over) is "only" a 505 Good luck Tony!!
