Yes. I had to make 1/2" spacers for it. It cost about $35-40 in materials and the bolts were a bit tough to find in the 10.9 grade. Well worth it though as I have a 3.80 upper pulley and can go to at least a 4.00 possibly larger if I have one made for it.
I took pictures of them installed if anyone is interested. I'll more than likely make a website for it sometime and host them there.
It ran, got up to operating temp and got shut off. Jon Lund will hopefully be tuning it Friday or Saturday.
Thanks for the kind words. I appreciate it, it's been a long time coming.

Very nice setup. What's your crank pulley size? I am building a 434 SBC with the Whipple 3.3 (target boost is 12-14# across the range) and am wondering where to start on pulley sizes. I have a 7" crank pulley and also a 6.66" if I need it, and I got the 3.5 8-rib for the blower.
How's yours sound under load?
Thanks,
Jim

stock crank pulley b/c it uses the factory brace.

once you drive one and have to use your go go gadget arm to shift 3rd or 5th you will rethink that idea. i myself love the way the look externaly and am in love with the blower whine and ease of making power with one but that was enough to ruin it for me.
Ive never had a problem driving one... im not really tall either.. im like 6'1"... i love driving them.

Sorry about that, it's a 7.6" pulley stock. Be aware that many sites will quote 7.5" stock but it is measured as 7.6" and I have used that for all calculations.
I'm running a 7.6" lower with a 3.80" upper and on my 284 it should be making around 21 lbs of boost with the Gen II Rotors and long tubes. We'll find out for certain tomorrow, I've got 120 miles on the setup and my appointment is at 12:30pm Friday to get the car tuned on the dyno.
As for the shifter, you're right it's not the most ergonomic. I'm also 6'3" and sit with the seat fully back and that's still not as far back as I'd like it. I don't lean back in the seat at all though and I can reach 3rd and 5th without much struggle. I do have the Pro 5.0 shifter with an MGW blue handle. That aside the seats are phenomenal, the interior is up to par and the steering wheel is actually leather wrapped. While it's not a Corvette, it's not bad for a Ford.
Wish me luck, I just want to get in boost again!

OK, thanks, that's useful. I'm mostly trying to see if I need a larger or smaller blower pulley on hand for tuning, but I guess it's going to be 'wait and see'.
Cool project - love those 4-valve heads...

634 hp 605 tq on a mustang dyno. 20.5 psi boost and not much timing at all.... we are gonna leave it this way for like 800-1k miles them add a couple more degrees of timing. It should make about 700 on pump gas with more timing.

Like Fran said, we had some conservative pulls on my pump gas setting and made 634/607 on a Mustang Dyno with very low timing and only pulling to 5900. The dyno operator quit logging at 5900 but the tuner pulled to 6700, and the power wasn't done rising.
I'd like to see 680-700 with full timing on pump gas spinning it to 6500+.
