Yea, I will post some up later tonight. I did ARP studs. The on3 kit went in w/ no modifications, other than I will have to extend the pipe attaching to the bonnet about 4-5".

you need to get a dist that is locked out, and something to control the timming.. 22 degrees is killing it down low, i would also start putting a degree in it at a time and read the plugs 22 is pretty low for 8 psi runing a blowthru setup..

but the carb seems to be doing great in the video..

don't have any at this time. I just ran it straight back to the downpipe. I used the extra flanges from the wastegate kit to make it removable. I will try to get some pics later

The dist is locked. I just got it running. I will be getting an MSD distributor and a 6al-2 to make my own timing curve. I will start messing with the timing more when I get the carb dialed in.

Allen, other than setting the idle/mixture screws and setting the float level, the carb has been almost a bolt on and go. Kevin at CSU is really great about working with you one on one getting the carb dialed in. The only thing the carb has needed was smaller idle air bleeds to cure an off idle stumble

it will be a beast when you get some real timing in it down low.. that 6530 is a great box to add to it...

Yea, I know and I can't wait. As soon as I get the carb going into and coming out of boost a little more smoothly, ill be ripping out the 6al and getting the 6al-2. I drove it around when I first got it running at 34* trying to dial in the off boost stuff and it was a totally different animal. It wants more timing, just need the funds lol

once you get the other box on it you may have to mess with the carb a little to get the AF right.. timming will affect it a little..

I live in concord, so we arent far apart at all.. I am also building my 2nd blowthru car...It will have a Brent Davis [Crutch] Blowthru carb on it..

Im sure I will have to mess with the timing some when I get it. Thats actually probably my highest priority.
