    Stroker kit or 347 block?

    Agree, supercharger most power for the money. Vortech strim is a solid kit. As was sItated earlier, close to 500rwhp with what you already have. And I just so happen to know where you can get a good deal on one with an aftercooler, a must for reliable/consistent forced induction power. 80k...

    YEAH IT IS. . . . And we'll make more. By the way, I just so happen to be looking through parts stuff last night and saw the box for my tb and egr setup, its only 70mm, not the 75mm I originally thought. Go figure.

    Yeah iif you're replacing the tb because its sticking then that makes sense. Why pay to dyno tune? We can do that. Just pay for the dyno time! Or wait for a dyno day. Or just take it to lebanon valley with a set of slicks and we can use the real world et and mph to tune it. Lol. -chris

    Started putting goodies in the GT!

    If you want my 2 cents, don't bother spending that much money on a bigger TB. Pulley it up +2 to +4 psig and be done with it. The pressure drop gains from the TB will not match the extra flow from the S-trim . . .or get yourself and aftercooler and crank up the timing. How much is dyno time...

    Started putting goodies in the GT!

    Well before we started tuning, remember we double checked the A/F and it pretty much matched the commanded A/F which is why we left the slopes where they were. I looked at the logs yesterday and it looks like A/F was off by 8% the other way now at idle so we can certainly change the slopes back...

    Yes about 20% off. Given that the MAF was just calibrated, I chose to believe it and put errors on the slopes (or offsets). But in reality, I'm willing to bet that the calibrations on MAF are not all that accurate at low flows (or maybe even in general), especially considering this one is...

    Started putting goodies in the GT!

    We tuned in the idle air flow functions and the WOT fuel multipliers yesterday. For the past couple of months we've been tuning injector slopes, MAF functions over the phone/email, wanted to get that straightened first :-) Worked well actually. We'll mess with the timing at the top end on a...

    Started putting goodies in the GT!

    Thanks for the props Gene. Definitely was challenging but you stuck with it and I'm glad to see it all come out well in the end. Maybe "well" is a bit of an understatement because I agree, the car is a beast. And don't forget there's more in it, especially up top. We'll wait for a dyno...

    A Cold Air Intake kit adds HP? I cant imagine how?

    Gains on CAI will depend on what else is done on the intake track, maf meter, throttle body, egr, etc. It's all about reducing inlet restriction/pressure drop and is only as good as the limiting component.

    A Cold Air Intake kit adds HP? I cant imagine how?

    Underdrive pulleys. Torque gains across the board by design.

    5.0 ranger cam suggestions

    Hmm, my bad I missed the comment on the auto but I get your point. I don't have any experience with the autos. What rpm do the stock converters lock up on? Does the stock ho cam really make significantly more torque down low than a alphabet cam?

    5.0 ranger cam suggestions

    B303 w/1.7 rockers or F303 w/1.6 pretty close cams and I think if you go on the Corral, there's a few dyno sheets comparing GT40 iron headed 302's with those cam's and like a TFS stage 1 where there was really no gain. I for one had a B303 in my cobra GT40 and it really woke the motor up. with...
