Ive been using the full HSR for awhile on my SR 383. I had some crappy stock ported heads(flowed 250) and went 11.01@120 N/A. I have made some changes over the winter so in a couple weeks I will see what it does Taner. I went a little to high on compression so pump gas is out lol.

Any pics of this? I would be interested in seeing the intake modified.
I can attest to tapout's car, should fly with the new combo.

GGPC,
clearance on an untouched cowl is basically a tick under 8 inches. if the lower hump is removed you gain an inch, and you can still keep your wipers in tact.
Tapout,
did you change alot over the winter? or is it the intake only? hey i look forward to your response.
thanks!

flow numbers don't mean ****
Another board member went 10.8X on a stock bottom end LT1 with heads that peaked at 248cfm. I agree more going on than just flow numbers.
Tapout is a good friend of mine, and the heads he has now are

Most info I can find is 10.66 and I cant remember the mph. I know it went faster than that, just cant find anything on it anymore.
After spending $700 on broke valve guide replacement and valves stems all at different lengths, I sold those heads.

Hey fellows, I thought this thread was all about the HSR manifold and not about how fast someone went or who has who's heads!! There are only four posts on this whole page concerning the HSR. Keep to the subject!!!

*OFFICIAL RELEASE DATE: MARCH 7th*
That date is set in stone. I'll create a new information/how to order thread that afternoon explaining the 3 stages, options, pricing, and answers to commonly asked questions. The HSRs will be available for B,F,Y and other LT1 setups.
For those with LT4s, we are in the works of creating an option for you guys. That will be available shortly.
For F bodies, The intake will be in the neighborhood of 8.5 inches tall. Now that WILL NOT CLEAR your steel 'hump'. So, we have 2 options:
1. When you order, send in your 'hump' and we will modify it to fit the HSR.
2. In about a month, we will sell a more cut down version that will be under 8 inches. That WILL CLEAR the steel hump. With the cut down version though, the runners will be shorter and plenum volume will be sacrificed a little.
So, March 7th. I know, finally.
