[QUOTE]Originally posted by copcar: [QB] Wow, I can't believe I missed this thread. I must be slipping. As to the OP's question of whether to go boosted or H/C/I. Always go forced induction first. Why? The reasons a-plenty. 1) It WILL make as much power as a top end kit and do so much more smoothly and safely. 2) Assuming you have the correct head unit it WILL be emissions legal 3) If done right it WILL be bullet proof and provide years of motoring bliss. 4) It's a freaking supercharger. it wins at the local turd burger hangout spot and hood pop. These statements assume the combination will be used mainly on the street and must pass emissions. As to the rest of the posts. I love reading how GT40 heads are "junk" and that AFR/TFS/Dart/ etc are the only way to go. Let me put this to the reader. I have tested NUMEROUS HCI packages on my own car (it was a test mule after all)on the dyno as well as at the track. My lowly gt40 setup makes within 10% of the power of some of the best numbers on the dyno and runs right on their heels at the track. And I'm running stock valves.... and stock block/rotating assembly. Here's the problem. Nearly every build I have seen never utilizes the HCI to it's FULL potential. What I mean by this is as follows (this is relevant to the op's question so bare with me). Why would one buy a high flow set of heads, intake and cam to match and install them on a stock block and call that a performance engine? To me that seems like a waste of time. Will it make better numbers than stock? of course it will but if one were so inclined to make this decision why wouldnt he/she maximize the combination. The answer is simple. Get the right bottom end to compliment your top end. OP, this is a real delima for you. If you were to go HCI only I would strongly suggest getting a fresh block, run at least 10.0:1 compression and go with whatever ad looks the prettiest for your heads and intake. For the cam stick with a custom grind or a F/1.7 combination (TFS stage 1/1.7 freaking rips on that combo as well) I know this combination will easily go mid 11's. hell my lowly gt40 combo ran 11.90's on slicks with all emissions hooked up through cats. I think you can see where I am going with this. Just get the supercharger. Set it up with a nice, safe tune and go light the tires up. Run whatever heads you happen to walk across for a 20-30 hp increase and call it a day. [/QB][/QUOTE]
