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.

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!

I agree to that, I was looking through the archives and found out that steve quinn went 9.71 at 138mph on a LT1 head that peaked at 276cfm.
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

I owned those "crappy" heads. That set up was meant for race gas,more timing and an higher rpm than the stock computer would allow.

I agree Art, but now Ill go just as fast on pump gas and the stock pcm. The stock heads I got off you done me well for awhile. Theres just always something better.

WHat did you do with those old heads Tapout?

And Art, did you find where Clydes car went 10.40@128?

It was actually 10.40 @ 127 IIRC

Think I read about it on a thread about single plain intakes or something.

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.

I know it ran 10.56@127, I entered it on the fastest LT1's list on Cz28.com way back. Dont recall the 10.40, but it probably did it. Car was damn quick. And had a good bit left in it. Damn thing left like a stock eliminator car!

at Gulfport in August? not long before the car went into the wall

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!!!

...and yours increases that ratio of off-topic content .

Oops, so does this one!

this adds to how fast an HSR manifold can go. DUH car picked up several tenths after the swap from a lt1 manifold to the HSR

*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.
