New LS1 swap headers?

[Jewmont3]

I found these... http://www.speedwaymotors.com/m/1120_Stree...Camaro-LS1.html
while browsing around. Curious if they might fit our obs ls1 swaps. the clipster headers are midlength or so but have 1 3/4 primaries and 3 inch collectors. Largest I have seen for anything but long tubes. Does anyone have demensions of what would fit in this swap? Maybe if someone had them we could call the company and see what their dimensions are for these headers. for $370 coated they dont sound like a bad deal!

Those are similar to S&P headers that Nitrous and Motoxlifer run.

I used the S & P&#39;s also. They fit my LS1 OBS very well. Gar

Do you guys know how much power you picked up with them? The s&ps are 1 3/4 primaries and 3 in collectors? I am planning a 402, 408 or 418 LS2 block so im gonna need to get some exhaust out&#33;

If you don&#39;t mind the extra expense I would suggest you get the LS2 or an L92 base stroker. Lighter weight and deeper cylinders help prolong the life of the engine.
As for headers, I think the S&P should work nice. It would be cool if someone could do a before and after dyno run on their setups before doing header installs.

Plan is an LS2 based block probably aluminum unless someone can convince me otherwise. L92 heads and L76 intake.
