I got a 1972 400 block that I am planning on turning into a 500 stroker, I am planning on using 440sources 500 kit with a 4.150" stroke and a 6.760" rod, 4.375 (.035) over bore and flat top pistons, anyone know anything about these kits, reliability, quality etc and got any good recommendations for heads and what a good cam is to run? It's going into to an 1988 Dodge D150 reg cab, long box, I want the truck to be very street able bit yet lay done a good time when I take it to the strip I am not sure what trans is going behind it quite yet but I am leaning towards a rebuilt 727 I have laying around. And one other thing I want to build it to handle a blower as it is the eventual plan to have one sitting on top in the next couple years
From what I've heard the 440 Source parts are generally up to par. Their Stealth heads are the cheapest way to go, if your cam is less than .510 lift. Edelbrock also has some good cyl heads/intakes for this engine. But more money, of course. If you goin to run a blower later on, keep the C/R down to what 8 to 1? Or less depending on amount of boost. But you can build a real powerful engine with out a blower, thru research and careful planning. Good luck!
I have a 500" stroked 400 using the 440 source kit. I used an older kit when they still sold the "I" Beam rods. Not sure if clearance would be the same as the "H" beam rods, but I only had to take a small amount off the oil pickup boss for clearance. Did not have to clearance the bores or oil pan rail.I used The flat top pistons with 74cc Edelbrock Max Wedge Victor heads, so compression is 12.4:1, and I am running a 0.714" lift cam. I have had problems with the Victor heads breaking the center rocker stand, and the rocker arms are $1,000 for those heads so I'm not sure you want to go that route?On the stroker kit, the piston pin goes through the oil ring land (not a big deal), but I had to debur around the pin hole for the ring support to fit in the ring land correctly. The 440 source pistons are Keith Black "ICON" pistons. You will also have to check the rods small end bushings as some were a bit tight on the piston pins. I think part of the issue is the rods get banged around in shipping and the edge of the small end bushing gets dinged. The bearings need to be checked and maybe chamfered if they are touching the cranks fillets.
