383 With Stage V Engineering Hemi Coversion Heads.

I would say go for it, something different? What are the cost of the heads and such to do the conversion? My goal was similar to yours, 700'ish hp, daily driver, though keeping it a wedge. I am guestimating I am at about 525hp at 4 psi of boost, still have some driveline upgrades to do before I bump it up to 10 psi. Keep in mind you don't need a lot of N/A hp before you boost it, I am actually planning to go to even a bit smaller of a cam than I am using now to help my fuel milage, and I also will not need as high of a stall converter for the street. So if you say your planning for a daily driver it makes sense to use a smaller duration cam, so you don't need high flowing heads and supporting valvetrain with turbos to reach 700hp, nor do you need a stroked out build either.
 
Looking at around 3400 for the conversion kit with hemi heads, rocker shafts, stainless roller rockers, rockershaft stands, and valves installed. I'm also looking at having a custom built six pak EFI set up lines, linkage, throttle bodies, rails, injectors, and manifold for another 2200. outside of that and adding turbo or turbos later I'm just gonna have the engine cleaned prepped and rebuilt to stock speck running stock cubes.
 
She sure is gonna confuse the heck out of any car show goer. A 383 HEMI?? Say what now?
 
Gotta have hemi pistons, I would think. Otherwise, the compression ratio is gonna be way too low. Plus they provide some squish towards the spark plug at TDC.
 
the unfortunate bit is I can get the pistons but do to clearance issues you have to run the plugs in the same spot as any wedge engine.
 
Wouldn't you want to run the plugs in the threaded holes that are already in the hemi heads?
 
I think you have to put the plugs in the normal location, center of cyl head. There would be no clearance issues, unless it's with the hood. Plug wires come out straight the the valve covers, between the valves.

looks like getting plugs sideways in a hemi head would be a challenge. What is the issue with the clearance?

He posted after that about the plugs being in the Hemi position so he must’ve misunderstood. As for dual plugs, I can see that being a problem with the exhaust rockers used with conversion heads.

I sure hope he did... that would be cool
 
Would have thought the expermental overhead cam heads would have worked better for this. If they had gone into production.
 
I'm in search for a pair of these Hemi Stage~V Conversion heads if anyone has a set or maybe knows of someone who does and is willing to let go of them?
 
Where those made by the company in Oklahoma. Maybe a long shot but could it be they kept record of where they went?

Stage V is still in business but no longer making the Hemi conversion head, they make standard racing Hemi stuff & Hemi heads for Ford & Chevy go figure??

Since he hasn't been here for three and a half years after posting for just one week, I'm guessing that it didn't happen.
