See it now, thanks, my mistake.

I think there is some confusion here about this engine. First of all this is the LS 7. This engine came in all 2012-2015 COPO Camaro's. SOME MAY BE CONFUSING IT WITH THE LSX which is a 427/450 HP version that is only eligible to run in a 2014 or 2015 car...

The LS7 discussed in the article is a good one to make 825...The LSX makes another 50 due to slightly more lift, and a different head, manifold and TB..

For the recird the L
S 7 discussed in the article races at 3200 # in the Shootout while the LSX runs at 3350#

This engine is raced in stock correct? It makes as much power as a super mod comp car in D/SM. And that comp engine has every trick in the book and more. Stock? You say stock eliminator? Did someone say stock........��

My point is stock certain has come along way!

Sorry but its not impressive.....and i think its lame to write an article like this on how "trick" they are for doing things that have been going on for ever in Stock...And as someone who makes there living in Stock and Super Stock i think those things should go unspoken, especially in writing!

Based on those air flow numbers the dyno I use would be about 800hp with the valve angle of LS another 25 would be realistic,ET @that HP,weight seems pretty close to me,just off top of my head.
The way I see it,it is their engine and if they want to tell everything they did,then that's their business.

And the bottom line to this whole discussion? Imagine being the guys racing '50 Oldsmobiles and Studebakers in 1962-64 when Detroit was releasing "Stock" Super Dutys,Z-11s, Max-Wedges and Hemis, and Side-Oilers and Tunnel Ports.
Well, welcome to the 21st century! Now we're those guys.

From the article
“so we milled down the intake flange surface to shorten up the length of the port just slightly. This gives us some extra room to touch up the short-turn radius, bowl, and valve job area and increase the cross-section a bit without exceeding the cc limit,”

From the NHRA Rule book
“Must be correct casting number for year and horsepower claimed, per NHRA Technical Bulletins or NHRA accepted. Porting, polishing, welding, epoxying and acid-porting prohibited.”

Based on this how is this motor legal?

Not quite. A bit before my time, but I believe in most cases, you could buy them off the showroom floor and drive them on the street. The one's that were not street legal went to SS. But that's already been debated. Yea, we'll just make the best of it.
