VRX460 Magnum
I'm going to play "Follow the Leader" and build a 460 as wild as I can afford. I want the added torque but not the high rpm. I was saving for a ARC billet crankshaft but the bottom line is there made and balanced for an 88mm piston. I would have to balance the crank, rod and piston over

Re: VRX460 Magnum
Sense I'm not looking to achieve more then 5000 rpm I'll use the stock crankshaft. The ARC crank would have to be balanced for the 92mm piston. I have a VC long rod at 4.510 topped with a Ross forged piston. On paper it measures .006 short of a full deck but I will know for sure when I assemble the piston and rod.
I assembled my block and external parts to figure my fastener count and make sure I have enough hardware. I bought a stud kit from NR for the head and side case. I'm still looking for my camshaft - I've learned from Ray and Mike that the rocker arm ratio is 1.3 to 1 on the stock hemi head. This changes all my numbers, now I start over with a search for the next stage cam. |

Re: VRX460 Magnum
Anyone know how many cc's the combustion chamber is on the hemi head? After checking over the head I can see that it's a better made casting over any stock casting.
The valves are bigger then stock heads and there's room for more. The quality of the combustion chamber is flawless, the valve seats are flush in the chamber and there is no shroud. Other then porting the hemi casting is perfect. |

Re: VRX460 Magnum
Can't wait to see what you come up with. Still wondering about the wedge piston with the hemi head.

Re: VRX460 Magnum
My big problem is how to hold my piston in the mill and not deform the piston skirt. I bought a block of aluminum 2x4x4 inches off Ebay. My plan is to cut a hole 3.625 through the block - this will leave me about .187 +/- web on the thinnest point of the square block. I can cut one side of the block and make a clamp to fit the piston in and hold it in the mill vise.

Re: VRX460 Magnum
I don't doubt your skills. Just didn't see an easy solution for the average builder with hand tools such as myself.

Re: VRX460 Magnum
To bad you live so far away. You need to find a friend close by that has a small machine shop. There are times I have to go to the big machine company over in Nichols to get work done thats to big for my machines. I made a cannon a few years back and had to have a breech plug made and the barrel internally threaded. You could come up for a visit

Re: VRX460 Magnum
Shepard watch Paul’s video on how to cut valve reliefs by gluing 60 grit red oxide paper on the valves and you get a exact position on the valves that’s how I did mine cuts pretty fast too
