I had a 454 bored 30 over, balanced crank, new cam, new head, new intake, new everything.
Dyno'd 560hp and has been running for years.
Don't forget you'll need a new exhuast.

I had one in my old Carerra and it had thru the prop exhaust and I could get 4200rpm out of it and I put on,Holley750,eddelbrock performer manifold,MSD ignition system,roller rockers,highflo sparkarrestor and ran the exhaust out the transom with stock manifolds and I picked up almost 400rpm and it ran like an injected motor,I would have got more with better exhaust but sold it before I did that and I had about the same hours when I did that and ran it up to almost 800 hrs with no problems.Those are great motors and respond well to mods.These parts are a good start without going into the bottom end and are all reasonably easy to install.You can just go to a mail order house like CP performance and get all parts from them.Have fun,I did.

Don't know the parts, was built by JC Performance.
IIRC, it must have been 5000+exhaust?
cant really remember, and try not to...

You are better off building/buying an HP engine, and keeping your stocker for when its time to sell.
Or even have a backup just in case.
Not a bad piece... especially if it comes w/ the exhaust.
