Im pulling the motor to fix a cracked piston want to upgrade while its out does any body know best set up im not going crazy with it but everybody tells me i can do a heads and cam change that will wake the motor up thanks Randy

You can't do any changes like that without remapping the ECU.

Yea i thought I would have to do that just thought there might be a certain set up someone had tried

Don't bother unless you are going to ditch the MPI. There are a few on here that have tried it, and it wasn't worth the $$. The MPI settup really limits the hp that you can make.

Possibly sell your motor and upgrade to a 454 mag or 502? Just my 2 cents worth....

Thats just the answer i needed to make my decision Thanks Randy

If you have the 454MAG version, you can make about another 100hp or so with modded stock heads, cam, exhaust and ecu upgrade. There are a few vendors who will sell you the whole package.
Tyler Crockett, located in Michigan, 810-324-2720 came up with this upgrade several years ago for the 502mag, and it applies to the 454mag as well. Its a dyno proven package. You can send them the engine, or they can send you the parts.
Teague also has a kit as well.
