yes all the crap that could get in the way does so, lol! it is a street driven car! I wouldn't possibly think of removing the wipers. they are a must!
my measurement allows one to squeeze their fingers through the top. The option is their to keep wipers functional and modify the lower closeout piece under the cowl that creates our clearance issue.
I am an odd case, i would love to see how this performs on a combo like mine without rolling the dice on a new conversion. I think this would probably perform near the level at what is under the hood of my car, at a fraction of the price.
GGPC,
could you take another measurement. could you measure from the outside at the back of the intake to the centerline of the distributor hole. I will do the same on my intake. the dist. i run is not a conventional "round" or circular distributor, and wonder if it is tighter than what i currently have.
so someone with a stout 396 SR, pump gas motor with a healthy camshaft please buy this and try it out, lol!!! must have Jesel topend with heads that flow 305 cfm @ .600 lift
thanks!

Cam is a bit over .6 lift and 24x duration on both sides. Hoping for nice numbers, but will not be testing on the LT1 intake first since it is a totally fresh shortblock.
As long as the price is cheaper then our current single plain options - which it looks like it is - and it performs better then a ported LT1 intake - which it looks like it does - I'm in!
I'm telling you, its a great time to be working on another LT1 build
. Dart and TFS both have new heads, progress being made on a more simple way to run LS1 coils and PCM, more and more LT1 cam enhancements by LE and AI, and to top it off a more mainstream single plain conversion in the works...I get giddy thinking about it all 
.This year is going to be big for the LT1 community, and I expect more and more fast cars to be coming out of the woodwork.

I plan on running it on my big HR 383 with AI ported 21* TFS heads which should flow around 300cfm based on their testing.

Both intakes are stock. No porting.

Speaking of a single plain, I have a old dyno archive comparing a HSR and a Holley SP. http://www.eecis.udel.edu/~davis/z28/winter01/dyno/dyno031229/webpage031229.html
Both intakes are stock. No porting.

I'm also interested in your Intake. Would like to know when will you have your intake so it will fit LT4 heads. I have a moded LT4 Vette with LT1 fuel lines, see sig.
Would you have any data comparisson of an LT4 intake and your HSR???

Too bad they didn't show the TQ from 2000--3400 rpm.

This would be comparable to a ported lt1 intake flow for flow. That unit above is $900.00.
We will have a HSR to fit LT4 heads. That will be released a little later though.

I didnt realize there were two threads one this. What about an LT1 Vette? Would the HSR fit under a raised hood like the toledo pro 2.75" raised center pictured below on the left? Would there be less work/cost involved and better numbers? I have a 95 LT1.
Thanks for supporting the LT1 community.

I finally found some 1/4 mile data comparing a ported LT1 intake and a HSR.
There was a guy,sig name was 12 SEC SS on ISSF, who replaced his ported lt1 intake with a custom HSR. His setup was a 383 with a 847 cam. He picked up 3mph and .4 tenths of a second over the ported lt1. He was pushing over 450rwtq with the Holley set up.
Heres the link:

.I was checking out the fuel rails on my 93, and it does not look too hard to replace the crossover with braided fuel line of the right length, but I am still not sure if the injector placement would be correct. Not too keen on being the guinea pig for that, lol.

I'm telling you, its a great time to be working on another LT1 build . Dart and TFS both have new heads, progress being made on a more simple way to run LS1 coils and PCM, more and more LT1 cam enhancements by LE and AI, and to top it off a more mainstream single plain conversion in the works...I get giddy thinking about it all .
This year is going to be big for the LT1 community, and I expect more and more fast cars to be coming out of the woodwork.

Pardon my oversimplification. Can't you just mill the runners until it fits and forget about the "air gap"? There are no center bolt holes, are there? So there isn't a problem there,is there? Aren't the outer bolt holes the same on the L98 and the LT1? I may be looking at the wrong intake, as I see a different one with center bolt holes. Is it the Vortech headed HSR that is being modified?

I have been doing some research lately on intakes and I plumb forgot about the BRE Pro Ram intake. If I am not mistaken it used a HSR base or a ramjet base?? Interesting though http://entertainment.webshots.com/album/167818222FYslag
This thread has actually encourged me to tinker with an intake design I have been thinking about for a while. So far I have cut the top off the stock intake and air gaped it, I have some pretty trick ideas and in theory it should flow pretty damn good. The manifold weighs about 3 lbs right now
