Would it be possible to run blowers off of 525SC mercs on Mark IV 454s? I have edelbrock alum heads but am concerned they might not mount up. If they don't is there a way to make them?

525SC blower packages have rectangular port intake manifolds. You may have to modify your heads where the intake ports meet or switch to an aftermaket manifold.
It will certainly work, but you may have to make some changes.

If you're asking if the bolt pattern between the manifold and head are the same, yes. So is the deck height.
As was pointed out, the 525SCs manifolds use rectangular port heads. Are yours oval or rectangle? If oval.

The Combustion chamber size on an Eldebrock head is less than a 990 casting hi-po head. This means your compression ratio will be higher than stock and you will risk the chance of blowing a head gasket or lifting the head. Do you have the performer, or the performer rpm series , The rpm 's are offered in a square port which has the 119 cc chambers, any of the ovals are a 110 cc chamber.

Thanks for the replies, it sounds like I may be in a good spot. Heads are rpms, rect port with open chambers. When I built them I used cometic head gaskets and faria exhaust valves. Compression is about 9:5 now.
Any idea how much boost I could run and what sort of hp increase to expect. I run a cam with 112 lsa and about 564 lift, 230 duration or thereabouts.
