Re: VRX460 Magnum
I didn't think it would work - I posted an opinion about it and after a lot of research and a few questions -- here I am jumping on the wagon. I'm looking for that extra few foot pounds of torque. After talking with Paul the other day -- was told "I don't see any reason it wouldn't work as long as you cut the valve reliefs proper". My research shows that most parts will interchange with a GX390. This is an example of parts fitting the 420 and the 390 https://www.gopowersports.com/stage-...rformance-kit/
If you take the time to do the hunt you'll find more parts that interchange. Yes Ray -- the head has a threaded boss to hold a tin cover in place just like what we use on our engines. I bought an engine starter kit way back and this is my platform for my build. I've got most of my parts - decided I'd use the torque cam that Vegas was using. It gives me .338 valve lift. Being the valves are bigger and the rocker arms are more frail - I don't want to go too high on the lift till I prove this will work. Once I get my camshaft I can mock up the engine and measure my push rods. I'm going to order a pair of push rods from this company https://www.tickperformance.com/tick...ngth-080-wall/ They advertise custom length push rods -- will see whats up when I know what to order. |

Re: VRX460 Magnum
It is funny. I was thinking "why doesn't Shepard just run the VC cam with all the extra valve and port air flow." On the push rods will they sell you 2 ? The 1/4"ers are being used by the racers at up to 8000 rpms with the pressure of double valve springs. I see somebody asked Jody Powell from ARC if anyone was making billet rockers for the big block hemi and replied not that he was aware of.

Re: VRX460 Magnum
The question was actually for Mikey. I was not clear what base engine he started with.

Re: VRX460 Magnum
I have been following your and Shepard's hemi builds. One of the predators came as a 420 cc hemi that quite a few youtube builders modified. BUT many of us were under the wrong impression that the 420 hemi head would not fit the VC block. So you were the first to suggest that might not be true. Paul's carts had said the hemi head was no longer available except on nos HF hemi engines on shelves. Which also turned out not to be true. I didn't see how Paul cut his piston but wondered if a valve could be turned into a cutting tool. Carry on you guys are trail blazing.

Re: VRX460 Magnum
Paul glues aluminum oxide disc on the valves and spins them in the head with a drill I used his method on mine
