I'm assuming with 13:1 comp it's not a street engine. I think the heads and carb are really gonna hold it back. But if i had to guess i'd say 625-650.
no i have it in a "street stock" pulling truck spossed to have oem heads tring not to make it noticable thanks though

Heres my swing at the pitch
572 pk HP @ 5000
681 pk TQ @ 3500
Nice combo shit loads of torque
@ 5000 rpm still has 600 ft lb tq
thanks it in a pulling truck that is great if have that much torque that low shouldn't puke at the end
anyone else out there with est? just wondering how you all get the numbers?

TQ is the advantage of running the smaller head..i also run a smaller valve head on a 565ci in my camaro (with a lot of Runner work),,,cause its a Heavy pig i run in the 1/8..so i wanted it to be a little more Tq'y.
i think Slickfuel is all over it,,could be a tad more HP..But not enough to beg the differ...
ok i will say 573 hp...same Tq as what Slick fuel says....LMAO
THE OLD PRICE IS RIGHT TRICK !

Right around 600hp...the heads are limitin you with that cam...go to an aluminum head that breaths better like Dart Pro !'s say 325's goes to around 700hp, 355's around 750hp....
