@heyoldguy ok, i'm fairly new to mopar and in germany it's an even more uncommon hobby. My knowledge is still on noob-status (but the library is growing!) Right now i have in the car a 440 with 906's, rpm-intake and a 770cfm carb.... I have no further info on the internals (only the number on the pistons told me that they are stock). So my guess is this combo is around 300HP. Since i want some more bang  i bought an unused 0.30over 76 block. With the block came a 4.150 stroker-crank (+ pistons + rods) and so i'll go for 493cubes. Compression 11:1 would be fine on pump-gas. The goal is 750HP (means around 600HP on rear-axle). I red threads where you also posted, that for reaching 750 maxwedge is not really needed. I assume that everything has to be built properly from the right pro without any mistakes to reach the 750HP. To be more on the secure side (some imperfections might happen in the engine-building-process or the builder is not 100% perfectly doing his job) i had the idea to go with mw-heads and a double plane indy 440-1 intake. Ok, still would need someone to pick the right cam for me.. ;-) ANY ADVICE what combo would also bring me to the 750HP-region ( no problem if it's "only" 725...  ) is welcome. The only things i have right now are: Eagle 4150 crank Eagle 6760 rods Speed Pro forged pistons L2266F Clevite M bearings (think "M" is for racing and i should go for "H") ARP bolts 440 block bored 0.030 over thanks + regards,smoke

well what i found on L2266F is with a 4.15 stroke and 6.678 rod they will stick over .100 out of the block?? Other than that I would go with Indy 440-1 kit right from the get go and have CNC ported before it is shipped to you comes with everything you need then you just need a cam. what you need for where you want to go!! comes with intake and all. and maybe upgrades in valve springs for roller cam and upgrade rockers to harland sharp or T&D and so on. Guys can give you the names of some guys on hear to buy from or wes at mancini racing. http://www.manciniracing.com/440-1 head kit! they will get them CNC at modern or by Indy and upgrades you need http://chucker54.stores.yahoo.net/in44hepr850h.htmlmaybe get the open access valley plate too well for sure!

You may want to slide over to "Unlawful racing and engine tech" section and title along the lines of "help me build a 750 hp pump gas motor" Lay out exactly what you have and goals EZ heads are only needed where clearance is an issue like an A body. on a B body just get the TTI indy headers 2 to 2 1/8 step headers for 440-1 and SR heads can be boght through Mancini's ask for you moparts discount! :-) http://www.ttiexhaust.com/Header-TTI440-218/HeaderDetails.htm

No, its the SR heads that are needed for A-body clearance issues. The EZ heads have a standard height exhaust port, SR's have a raised port.

Sr's are raised and extened very tight in an A body
The EZ's with stock location give more room!

X3 , the EZ's are best used in A bodies.

I believe Indy actually made the EZ heads for the A-body since it is a tighter fit then the B-body. The other Indy heads with the raised exh port had problems in the A-bodies with fitting right and not hitting things. So this Indy head (the EZ) was done by Indy as one of their good heads but with the exh ports in standard location so headers made for A-bodies made for standard exh port location will fit good in the A-body. Indy raised its exh port to get better flow on their heads. But after seeing the problem with fitment on A-bodies they came out with the EZ heads and standard exh port location. Of course you can use them on any car but they do fit better on the A-bodies then other Indy heads. Also the EZ heads use stock rocker gear and not offset rockers. I myself use the EZ heads on my 63 as I wanted the standard exh port location and standard rocker arms. Its less hassle and cost then if I used any other Indy head. I could probably make more power with a different Indy heads but the EZ's make pretty good power for having the standard exh port location. Ron

The SRs require the expensive TTI headers or a custom set, but they probably have more potential than the EZs due to the raised ports. The EZs, though designed for A-bodies, will work in B and E-bodies as well and don't require the special headers. The EZs might be able to make 750 HP, but you'd have to ask around. The SRs can make 750 HP more easily, in my opinion. Both the SRs and EZs use standard rockers, but the 440-1 heads (which aren't necessary if you're only trying for 750 HP) require off-set rockers. Ithink that the Super Stealths would require quite a bit of work to make 750 HP.

guys, thanks for all of your valueable input. The picture gets more clear... from post to post... I will have a very close look for ported and matched EZ (opened to mw) + indys 440-2d intake. Since i want to go with stock hood i have only few options regarding the intake in mw-size. If there is another solution (maybe opened but not fully to mw-size and taking a better flowing intake) that will have nearly the flow of the components above... let me know. For now i'll have a  on you.
