Yes, if it is the Merc 454cid/365hp engine, then it is strong enough for the superchargers, but I am not sure if it is wise to add a supercharger to that specific engine without doing a complete rebuild. It may be better setting it up/rebuilding the engine with a supercharger in mind. I know you can add a supercharger to some of Merc's later model engines---but I am not so sure about the Merc 365hp model. Perhpas someone else can chime in who would know for sure about adding a supercharger to a factory assembled Merc 365hp engine.

If you want to SC it, then you should still pull the heads and get new inconnel exhaust valves and use better head gaskets.
You will still need new carbs and if you're going SC'd, I would recommend you have Nickerson set them up so you don't have problems. Keep in mind, you will have to run 93 octane fuel.

I cannot get lower octane than 95 in Austria!
Which carbs you would suggest?

Which SC you would recommend, without destroying the engine. I don´t need 1000 hp (not this year).:D

do you think this is possible under 10.000,-?

Holley 1050 Dominators. Have them set up by Nickerson. http://www.nickersonperformance.com/


Blower Shop 250's.

You should make about 575 or so HP at 6#'s of boost.

200 Hours isnt much for the 365 mags. I have seen them go 900 hours without removing a valve cover. Depends on how they were used and maintained.

I would definitly upgrade the exhaust first. A fresh valve job and inconel ex valves. Add a cam, roller rockers, and 250 series blowers, 1050 dominators. Like Griff says, 575HP all day.

I run 177 blowers, which are smaller than the 250's. Everyone says they are too small, which creats heat. While this is true, these blowers were used on 454's(525SC) with very reliable results.

You can just go with new exhaust, valve job, roller cams, roller rockers, and keep your Qjet and GM aluminum intake with a spacer for now. As long as the q-jet is setup right, they can be made to support 450HP or better. Which is where I think you'll be with a exhaust upgrade and cam upgrade. Then add a blower kit later.

If i will get a good offer for my engines here in europe, i think about new ones, but i am pretty sure, i will go just for the dana exhaust, then see if i am happy with it. if not, i can think about cam, roller rockers, intake, head work and carbs; maybe blowers.

Silly questions: Can I use my Q-Jets on a 250 blower?

No on the Q jets. They are way too small at only about 750cfm.

Contact MIKE KNOKE in germany,,,he will hook u up with engines.
