Not sure of my power goals....I'm so used the old sbc and their challenge to make power, in my experience there isn't a sbc out there you can mill a set of stock heads and with a decent cam make the kinda dyno numbers I see the LS motors make (or claim). So my goal? Haven't got a clue. I read that car craft article and I get blown away at the minor parts it took to make the power they claim. So, is it outta line to think 500 hp is easily attainable? I'm not a hp junkie, I'm more of a complete package kinda guy....my last build made 375 hp at the wheels and ran 10.90's in 4000' da....
I'm lookin more for ET goal I suppose....I haven't weighed this car yet, but I would think if I could get close to 500 hp from this 6 liter, 10.90 might not to far outta reach. So, is 500 hp obtainable with the 317 heads? I have considered the L92 heads cuz I work at a GM dealer and can get em a little cheaper than the average cost...but I'd the L92's or the 317's aren't what I need, then which head is the right one? I keep hearing LS3 head, guess I don't really know what that is.
I'd love to learn the EFI tuning stuff....and once I get the car turn key then bring on the tuning challenge....the help I need is the preliminary stuff....

well... I have made the decision to go EFI....might as well...I'm just afraid of it...dollar for dollar it isnt that much different either way. Now, for what combo of intake and heads...t-body and injectors. I understand it goes back to power level goals, but like I said before I dont exactly have any. If I could make 500 hp at the crank i'd be happy. So, with that being said, it kinda looks like LS3 heads/intake are the favored choice? I am not familiar with the head numbers to which are LS3 or whatever they are LOL! What I DO know, I have 317's currently on this motor, which I read arent really worth usin...Money isnt really an issue providing the heads are GM castings...I'm not really interested in aftermarket heads. Furthermore, I am somewhat interested in astetics as well...and there are some pretty cool lookin intakes out there, OE intakes are ugly as ****...SO...anyone know where I'm goin with this?
