I agree with Gary K. don't see the gain over a well massaged Wildcat. Have ran them with 4500, 4150, AFB, and Q-Jets. Never gained anything to talk about with other intakes. That's on a 6500 rpm engine with Stage 2 heads. Now running 800 Edelbrock on the Wildcat (because of class rules) and bumping the rev limiter at 6600 at finish line. Wish I could get the latest block,crank, heads, etc to show these Mopar guys I run with that a Buick can get down in the low 9s with them. Jim N.
Not to mess up this thread, but Jim, what can you run as far as engine in NSS? BTW I caught you live on the Web a couple weeks ago. Loved seeing you pull up with all those Nopowers! I would love to see you serve up some smack down to those boys also!!!!!!!!!!
I talked to Robert Makely on who does his heads, it's none other then John Marcella of Marcella Manifolds. I explained to Robert about him doing intakes, he said he is gonna talk with John Marcella about custom making intake's, from heavily modified cast intakes to full custom billet made intakes. This is the guy That I would have my intake done at. Chad Speier of Speier racing heads is doing Buick heads, he is the guy that has been doing the cylinder heads for CP-Carrillo at the Engine Masters. Go to Facebook and search his name, he just posted a bad but flow sheet from Eddy heads. Needless to say, they are a serious contender to Ported Ta heads.
The engine is wide open, except intake (no sheet metal). Also carburetors, Buicks can only run AFBs, (including Eledbrocks) and Q-jets. Can run 2 AFBs or one of others, no Holkeys unless you can run 9.75 or better in FX. Tires are limited to 10.5W. I have ran 10.11 but can't get to 10 flat. I have a short block that has not been freshened since 2005. It's a stock rod engine that limits rpm. It would take very little to run 9s. I'm just 464 cubes. The Mopars, Fords and Chevy's are running close to 600". Have all aftermarket parts (blocks etc.). Some good TA parts in my car could run with them. Any donaters?
To bad we couldn't get our hands on a mopar intake for the testing, SP2 was 911@6700 vs 929@7100 for the SPX
