looking into turning my 454 mag into a 525sc,wanted to know what parts are the same and what i would need,blower,carb jet size,camshaft,is the compression the same,cylinder heads the same,fuel pump?

Griff

Crane cam #132561
Roller rockers
Gil or CMI exhaust
Comp ratio is 7.5:1
Ignition Module

You could easily just bolt on a 525sc intake, blower and carb package. Just increase the pulley size and lower the boost a little to compensate for the higher compression. Stock boost is 5.5#

I would run a 1050 dominator. Dont think the stock one will be big enough.

I think that is what is on the 525SC...

Did exactly what you are looking to do...I'll see if I can dig up a parts list.

Call Tyler Crockett, he'll sell you the cam and do the headwork you'll need. He did this for me and it turned out beautiful. The motors were awesome from power to the idle. He set up the carbs for me and they idled and accelerated like EFI. I sold the boat and I don't have the specs anymore. He works with Quick Fuel on carburetors. He set up modified 850's boost referenced for me. Much cheaper than the dominators. They build what you need and test run each carb. Tyler will sell you the components you need at a good price and give you the tech support you'll need to avoid problems. He recommends mild rework of the head, bowl work, seats, guides, valves, etc...he will do, crossover, exhaust upgrade, MSD ignition, Fel-Pro head gaskets. I went with custom CNC Brodix heads although Tyler said it wasn't a cost effective upgrade. He said my package would be 650hp. I never dynoed but my speed increase would indicate this to be accurate.

eagle did you go from 454 mags and how much speed did you gain with the conversion?
