Okay now that it is available again I need to make a decision. I have a fresh rebuild with raised compression and a comp 252 cam. Original carb and distributer and mild porting. 1966 mustang original engine. How much power will this add to my motor? Of course a 2 or 4 barrel and headers will prob have to come also. If I change to headers now and a duraspark how much extra will this head get me?
Aluminum head

have U read the "Classic Inlines" archive on any Index page here on this site @ every forum?
It's stared for this forum.
Nother good source many of us use is the "Performance Handbook" sourced from Matt at vintage inlines dot com.
While waiting for delivery go to the 'archive' for good info on that head and intake...

There are a bunch of dyno results that you can find in the old archived site. You can access is through the vintage inlines llc page. One used who upgraded to the CI aluminum head, dui ignition, dual outlet headers, 4 barrel carb and a t5 TRIPLED the motor's horsepower (211) and almost double the torque (227). In a 2500 pound car, that's not bad at all. 27 mpg to top it all off.

This link has an interesting chart showing an increase of 17 hp for DSII and headers on a stock 200. Not sure which mod provides the most. I have always thought that a DSII could add up to 10 hp approximately but have no proof. Hopefully some experts will provide some info on this.

Sorry I did not read your question correctly you want to know what the headers and DSII will produce when later adding the CI head.
As far as your question about hp will you get with a cam and increased compression I would like to know that my self because I considered building a 250 for my Bronco like that (and the mild porting).

I get that but another 12 from using an hei module/dui distributor? It was after the aluminum head and all the other upgrades, but the 4 barrel, that seems like alot. Maybe they never recurved the DSII, like rich said, after they put on the head
RE:Cost of the head.IIRC from reading the post on vendors site it will include the intake manifold also.Good luck.Have fun.Be safe.

Good to hear you got a definite power increase with those mods. The Falcon Performance Handbook has lots of info on DSII/carb upgrades and is a valuable resource in general. Check with a member on this forum, wsa, he can get you a rebuilt custom curved DSII for your 200.
