Guesses for a "diffrent" set-up? I don't usaully post things like this, but since the set-up I'm building is a bit "out side the box", I'd like to get some feed back on how ya'll think it will do. Set-up consists of:
HPE 454 ci LS2. 11:5:1 (Sleeved/4.150 bore" x 4.185" stroke)
ET performance 265cc race heads
25x/26x .650+ lift 110-112 LSA (still determining final specs)
FAST 90/90
Kooks 1 7/8" stepped to 2" headers
3" or 3 1/2" X/duals dumped
M6 tranny thru Moser 12-bolt
It's deffinatlly something you don't see everyday. I'm hoping to surpass 600 rwhp on pumpgas. Feel free to post up your guesses or ask questions if you feel I left something out. Thanks

Brandon, erik hasn't really mentioned how much power it should make yet. he's been so busy trying to get all these parts ordered, that we haven't really had time to talk much about it. That's not bad or a price at all Just wondering about those heads, has anyone thought that thay could be too big and lose efficency?? I would think with that much flow you would want to fill them with as much air as possible. Say a solid roller with your duration that you want but a .700+ valve lift.

615 rwhp, 570 rwtq. If you were running something better flowing than the FAST 90/90, I'd guess even higher. The intake is going to be the biggest bottleneck of the system IMO.

That should be wicked nasty. I'd have to agree with Patrick on that the intake will be your biggest bottle kneck. I certainly hope to get my motor sometime soon and slap this sb2 intake on and 1550 cfm tb and see if the intake is truly the bottle kneck. I just have a puney 434 though, lol!
