FIRST PICS PRC LS-3 Aftermarket Casting Cylinder Heads Sneak Peak INSIDE!! - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Lonnie@Texas-Speed · 05-13-2010, 03:24 PM

After nearly a year of development we're finally to the point where I can show you guys our newest LS based PRC castings! This all new casting is the PRC LS3 cylinder head & will be available in MANY different configurations ranging from LS1 friendly LS3 heads all the way up to large cube LS3 stroker applications! We don't have flow data or anything like this at this time, this is simply a post to let you guys checkout the progress & know we're working hard to make these cylinder heads a reality. The new changes to our castings will allow many new features on both the LS3 head & the cathedral LS heads! Keep your eyes open & we'll keep you guys updated on progress!

Hey Matt,
sorry im not good with car language. But what can these improve and what do people swap the stock ones ou for these for?

ron10 · 05-13-2010, 03:36 PM

very nice.

Lonnie@Texas-Speed · 05-13-2010, 03:38 PM

Without being able to go real in depth about the details, we are working to give the option for a smaller chamber than the LS3 head with more valve drop, which means more compression without milling and increased piston to valve clearance and the ability to run larger camshafts without flycutting!

Does that help?

awesome

wbt · 05-13-2010, 04:54 PM

Any additional unshrouding of the vavles as a result?

Jason 98 TA · 05-13-2010, 07:42 PM

absolutely, as well as much smaller runner options!

R1CH · 05-13-2010, 09:44 PM

Can't wait for more progress.

COOL! I see you're looking at smaller runners, too? So are you guys working on LS1/2/6-styles, too? I got a little lost in the original post regarding that.

How about this: What style (cathedral or rectangular) runners do you guys think is superior? I'm seeing some huge rectangular port heads that flow all the way up to +400 cfm (@ like .700"+) but haven't really gotten a feeling of low-lift flow. I know there are some large cathedrals out there, but I haven't noticed any that are reaching the flow of the squares.

Thanks and looking great!

I'd be interested in the velocity as well. Large flow number's don't mean diddly if port velocity is compromised.

Looks awesome jason!

Jason 98 TA · 05-16-2010, 11:48 AM

Guys we already have cathedral heads completed. We have a 215,227,237 cylinder head already available. We're currently adding this LS3 based head to our line!

danraz98 · 05-16-2010, 01:04 PM

Ok don't really understand the tech talk. So about how much hp would these add on average?

Jason 98 TA · 09-30-2010, 10:16 AM

Just to give everyone a update we're working hard to get this project completed & ready for production in about a month!
