Has anyone seen the new Dart Ls3 11,000 rpm, reversed intake and exhaust valve position, 2.3" int 10 degree canted valve, Jesel rockered head? Makes ls7/lt4 and Mast heads look like toy's. It even has an old style Hemi plug location right in the center of the dome in the chamber.

 

 

Whoa..... haven't I seen this before? Deja vu all over again....

 

 

Dart has just gone insane with these things. I just happened to catch there add on u-tube and they stunned me. I clicked on the add expecting to see the ls3 pro1's I have on backorder for over a month and a half now at Tick Performance for a new ls3 426CID stroker, Jesel, Drag race specked Cam Motion build and they were huge in comparison. Good thing the valves are canted or they wouldn't fit in the dam stock ls3's 4.065 holes. lol. Just sick!

 

Saw a set of the Dart canted valve LS heads for sale on Racing Junk - just a little over $9,000 with titanium valves

Sounds like a 1,000+ hp capable head NA, ideal for a Horsepower Research 454, 468 & 527 cube LS engines.

That's a pretty expensive engine to build. I talked to a guy who owned a Mallet LS1 Corvette. Back in the day, Mallet charged 30K for their head and cam package and it still had the stock LS6 intake.

 

Now I have.
