No complaints with my out of the box CV1 heads. Same with my wideports.

They are known for having problems not so much out of the box but when they are highly ported and the engine is high effort. Try and run lean and mean and those cylinders that don't feed as well burn plugs, crank seats or WORSE.

OHHHHHHTHEHUMANITY !

WHO IS RUNNING THESE HEADS MAX EFFORT USING MODERN ELECTRONIC TIMED PORT FUEL INJECTION ?

OR OLD SCHOOL CONSTANT PRESSURE MECHANICAL PORT FUEL INJECTION ?

How about 2x4 tunnel rams w/split Dominators or individual runner Weber type carb set ups?

Under boost w/ electronic or mechanical port injection?

ARE THEY EXPERIENCING THE SAME FUEL DISTRIBUTION PROBLEMS?

Seems like more of a manifolding issue when single four V carb or single TBI is used?
That's always been a problem for any V or inline engine ( to varying degrees) with a centrally located carb/ throttle body using a wet flow style manifold.
The inboard cylinders will burn O.K. & the cylinders to the front & rear will have issues either running lean or pig rich.

CV-1’s...2-4 intake, injection...Nitrous...god only knows how much he spraying. 535-540 CI. Claims 3140 #’s. Must be good size cam he’s running 1200 open spring Pressure.

I’m not exactly sure on CV-1....but I think is a 330 cc port..don’t know how much the flow...the e-heads were only 270 cc port. 511 CI. And only flowed 370 cfm.

PS: 370 not 270 CFM on e-heads

The heads you have right now would tear up Fultons CVs with the right intake .
I would like to see someone do a Kinsler/Leech kind of effort with them.

Mighty TA :
I would have put a Pontiac in it too. Try to buy or build a 5000hp capable unit? Time, spare parts, and reliability wonít be on your side.

Guys! I love the Pontiac engine too. But you canít do what you can with a 481X to this level simply because of the size limitations. My 572 is 4.5X4.5 with free flowing heads built for that size of bore (no one, not even Bill or whoever is your favorite, can build a head that can match because of the space constraints in the physical size of the block and bore, period!) so if you are ever on a sticky track you will get pulled on the top , period. And yes, billet components are on the shelf with at least 3 suppliers so you can keep racing when you break, and 4500hp will hurt parts no matter how good you are. If itís a slick track everyone has a shot!

As for the BBC and Hemi discussion, a 481X is a stand alone specifically designed race engine. Itís no brand of engine other than AJPE.
Now the truth comes out...LOL
