more 454 power
What is the best way to get a little more punch out of my 2000 454 (310 hp) multiport injection with a bravo III? I have ~1000 hrs on it and have lost ~ 200 rpm over the years (4600 down to 4400).
Is there an after market chip that would help? |
valve job

Valve job will help for sure.
Install the roller cam and valve springs from a Gen VI 454Mag. Have Tyler Crockett recalibrate your ECU |
1000hrs---about time for a full rebuild, not hp increase mods.

You need Rings, Bearings, Oil pump, and Valve Job as a Minimum. |
Do hp mods with 1000 hrs and it'll come apart for you ! No tools needed. BOB

Wow, I didn't think it was ready for a full rebuild. It runs strong, tight and no smoke. I guess if I've got it apart for a valve job I may as well do it all.
Thanks for all your input! |
I agree...a 1000 hours would probably be rebuild time. A fresh engine will bring your power back to where it was, but if you wanted a little more "punch" beyond that while you're doing the rebuild, then perhaps some bowl/pocket porting/short side radius work on the heads, some aftermarket exhausts, recalibrate/modify the ECU might give you a little more kick . Check with Tyler Crockett---I'm sure he can give you some ideas.

I imagine the top end rebuild will get your rpm back. If you have good oil pressure, and don't burn much oil, that's what I would do.

A good freshen up to start .
