Quote: Quote: Quote: there are no stock 1/2" lowdeck oil pickups. 1/2 pickup is PAN dependent and you can get around that if you use your brain ,it's has nothing to do with the blocks deck height . if you want to get TECHNICAL there were no WEDGE MOTORS with a 1/2 pickup . if you REALLY want to get technical you can kiss my your name fits you PERFECTLY ...

BTW i was just joking something this place needs a little more of. i wouldn't say ALL wedges though.. what about the Max Wedges Last edited by STUPIFY; 07/07/08 12:15 AM.

If you build it bigger than that then even the Max Wedge sized heads won't be able to feed it past 7000 rpm. If you want a really high revving low deck motor then use B1 heads. But that is a much more expensive project than what it sounded like you were proposing. You should be able to get headers for a low deck 470 with Indy heads. Not so sure about the Victor heads since the ports are moved. Lots of things are related to each other so you have to think thru all of the issues when you select a combination of parts.

The lightweight pistons should make the engine rev really well, but I can see how the short skirt of the piston would rock more than the taller 470 cid stroker piston. I figure this will wear the rings faster, but on the type of engine I am building it might get inspected and freshened up every year or two anyhow. The 451 Stroker I had, laster 12 years with no problems then the intake valve broke and holed the piston, and nicked up the cylinder, plus made a mess out of the cylinder head in that chamber. otherwise it was a very reliable engine, but give up displacement to the bigger stroker engines. We just fired up my friends 470 last week. I guess we will see how it performs and lasts..

I built one for my 74 Dart a few years ago and the new owner says it is still going strong with zero problems. Of course if your intention is for race only then that is another story. www.picturetrail.com/hemi_ram

I would run the 500 and get a kit with the longest rods. Longer rods put less side load on the piston and the overall height of the piston (Crown to tip of skirt) should be the same. If you are dead set on a 7000 rpm motor though then get the 470 and still use the longest rods you can. If you have good machine work and quality parts then either one should last a good long time. I am not causing global warming, I am just trying to hold off a impending Ice Age!

I guess from all that have posted about this that I will probabily build a 470..but it isn't carved in stone yet..LOL I also will check out all of the aluminum heads and see which ones will flow from the bottom to the top of my RPM range. If anyone else has any other thought on this..Please let me know. Thank you!
