looking for 454 mag upgrades or maybe new motor
 

was curious what i could do to get a little more horsepower out of this motor? if this would be the way to go? or look for another motor that i could drop in .. any help would be great thanks alot, motor has 600 hours on it , no smoke , doesnt burn any oil , just looking for a winter project

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.

hey
 

anyway to keep the silent choice option? kind of nice it doesnt have to be loud all the time haha , what was the cost on doing all of this ? and what parts did you use .. next question what will the bravo one leg handle?

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.

Had to run 93 octane.
Don't know the parts, was built by JC Performance.
IIRC, it must have been 5000+exhaust?
cant really remember, and try not to... :lolhit:

hey
 

haha thanks alot , ya its efi ... i may look for a complete motor and just keep this one on the shelf, or supercharge it not sure yet winter is coming soon

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.
