DCI RAM AIR V CYLINDER HEADS
 

Just found these online while messing around. They are pretty proud of them price wise but it looks like you could build an interesting street motor in the 455 or larger category if you had the coin. Looks like you could roll a tennis ball thru those ports.

I’d like to have a set myself. My understanding is there’s still a good bit of custom work that has to be done. No off the shelf headers, missing water cross-over. I’m not sure how difficult getting the correct pattern cam would be.

Don has posted some pretty impressive pump gas numbers to DCI’s Facebook page though.

There is allot of information in the race section about these heads. The "cool" factor is off the charts with Ram Air V heads. Making the change requires a special cam because of valve layout, Intake manifold and there are no exhaust manifolds. So custom headers also required. So the heads and associated valve train are just the beginning. It would be an eye popping, tongue wagging crowd when you opened the hood for sure. My 62 Catalina may have a set in it's future.

NOT for the weak of wallet!Tom

Not exactly for street engines in my not at all humble opinion.......

:cool:

Not a tennis ball, but a Golf ball and 3/4s!

...or the stock hood crowd.

Those are not DCI Vs or intake. That is McCarty Racing components in the pictures you posted.

I was thinking that Don has someone doing headers, dougs maybe??

According to his site, he has mad dog doing headers. I do also believe that his intake will fit under many stock hoods.

I could be wrong but I thought that was something that Don had said early on - they had the choice of making it fit in stock configurations or not and had decided due to performance to not worry about it.

That may be correct. I know I had seen something to the effect that they were at least trying for that.

Yeah, not a street head. In order to take advantage of the flow, it would be upper RPMs, and the power they would make by taking advantage of the flow, aftermarket block IMO.

DCI has many port sizes for their RA5 heads.......from just street to hold the F_CK on! :)

That I didn't know, haven't seen any street versions, only what's been posted in race.

Now I'm curious, will have to look deeper!

Wow, those as-cast flow numbers are in wide port edelbrock territory.

Yeah Don has mentioned on Facebook at several points that he designed the heads primarily for the high performance street car segment. I think he was targeting 455 and stroker 400 markets.

Guys,a STOCK factory V head is about 320!They can go to 400.My street port heads were in the 370 range.Tom

X2, have personally flow tested STOCK factory V heads very close to that number.
