I have been to decide weather i should run a sdpc intake with vortec heads or a stealth ram with ported and polished 202's. i already have both sets of heads and i think it will be more expensive to run the vortec setup what do you guys think i should to get the most power

thanks

 

If your thinking 'bout vortec style heads, perhaps
you should consider the Chevy ramjet intake.

 

Vortecs will out perform stock 202's.
The Ramjet isn't to much more than the tpi base.
Do a search. Also, S10wildside just bought one, so he know what's needed and price.
Not sure of the vortecs, but 202's don't fit a 305 IIRC.
Not that I've ever built one.
But I love my Vortecs. They were just too small for the rest of my combo..

 

For a street car vortecs are great, I really like my combo. fun to drive, plenty of torque, + decent top end. A HSR with heads and cam will undoubtedly make more HP once tuned. I don't think a HSR with stock heads, cam would be that great. My sdpc/ hot cam car is fast enough to hang with most things. I raced an old lady with a navy blue 2002 SS just like mine, ( she suprised me, she knew what she was doing) Up arroung 90-110 or so was pretty close. High speed the SS is faster. Really if you want top end go for the HSR, but stop light to stop light the vortec's are pretty cool+ great driveability.

 

holley is currently designing a stealthram for the vortec heads. If you want to run both just wait until the end of fall/early winter. That's when it's suppose to be done according to holley.

 

holley is designing a stealthram for the vortec heads right now. From what doug flynn posted it should be done around the end of the year. So if you want both you can wait until then or go with whichever combo you choose. Alot of info on the stealthram at www.stealthram.com

theres an article over there about how much the hsr helped a mostly stock camaro run into the 12's.

 

IT SOUNDS LIKE EVERYBODY ELSE IS THINKING WHAT I WAS THINKING BY GOING WITH THE VORTECS. I ALREADY HAVE MOST OF THE PARTS THAT WILL GIVE ME ABOUT THE SAME SETUP AS KENNERS (MINUS THE RUNNERS) WITH A T-56 AND 4.10 GEARS I WAS JUST TRYING TO DECIDE WHAT INTAKE SETUP I WANTED TO RUN. I SURE WILL BE HAPPY TO GET THIS L98 BUILT AND GET THE RAGGEDY OLD 305TBI OUT OF THIS CAR

 

I can vouch for that thappening.

 

The car in that article is not mostly stock. From the article itself...

A recap of the test vehicle's combination of parts shows the IROC to have a 9.8:1 compression 355ci small-block with box-stock TFS G1 heads. The cam is a custom grind flat-tappet hydraulic from Competition Cams (218*/228* duration at .050-inch lift). Fuel is added by flow-balanced 24-pound SVO injectors. A homemade ram-air system utilizing K&N filters feeds the engine through a modified mass airflow sensor and 52mm BBK throttle body. The exhaust is comprised of 1 5/8-inch Hedman shorty headers a single 3-inch Race Series Dynomax muffler with dual outlets. The TH350 transmission, TCI 10-inch stall converter, stock 3.23 rear, and Auburn limited slip unit rounds out the drivetrain. Traction is supplied by 26x11.5 ET Streets with the only weight reduction coming from skinnies up front.

Do check out that article...it's a good read!!

 

Please don't read into the GM high tech article. It's a fluke at best.

 

No intake alone will get a stock Heads/cam L98 into the 12's. just the notion of that sounds crazy. Mabey their is one or two people who are lucky, (Have a factory freak) and have tuned their car to the max who have done this. But for your average backyard racer this is impossible on a stock L98. What, I think a few people have broke high 13's with a stock L98 and stealthram, with alot of tuning. Of course add a cam, heads or both and this changes. All I know is it takes alot more torque/HP than an intake provides to go from 14.5(bone stock) to 12's

 

No fluke. I've been building engines and tuning cars at the track for over 23 years. The car ran 12.6s in near 90 degree weather and mid to high 12.3s right at 110 mph in 48 degree weather - sea level track. It's one of the slower cars I've built and tuned on in years,, but it was originally intended to be the wife's car and I was in the right place at the right time to do the story for GMHTP. I have no hidden agenda and will be more than happy to discuss any thing about the car in detail.

 

I awlays wondered what the GM HTP HSR car would do with a real tune :-) No FP and jack with timing garbage but a real honest to *** tune. Timing done to best results and the MAF tables worked thru and the PE stuff dialed in with a wideband and some track testing.

Methinks there is a decent amount still left in it sitting on the table due to tune

later
