Just to relate, I will share my experience too. I noticed mine (efi) had HUGE ports compared to the old PP. IIRC, you already have 205cc heads on that and that intake is prolly really gonna wake it up man. I dont see u losing much low end ,we already have too much.
If I keep my car, I may eventually go with a spider or something considering I am revving higher with the 3.90's. It revvs so fast now, I barely have time to shift it! Rick says mine will spin to 7k NP. Of course cam is also part of it. The cam I have now gives me more low end than the other one I had but still should spin pretty good to like 6500 I think. But I stop pumping out power @52-5500RPM IIRC. I am making roughy..450rwhp now street tune. I say roughly bc I was making 421rwhp on a dynojet and Rick with RNH Performance got me another 50rwhp from that baseline on a mustang dyno. Let us know what you get.
Also, I remember changing from a street to a track Heat intake on the 306 and it kept the power low and revved much higher. Felt like a 32 valve!! I hope u get the same result.
