I think I’ll be pulling the trigger shortly on an AFCO coilover kit to replace the Vikings.
300# front and 175# rear springs.

May also be going to a Moroso vacuum pump setup running off an ATI damper, to take care of some crankcase pressure, which may have been causing my coolant issue...F body wet sump vs C6 dry sump may be causing the pressure increase

Does anyone know if AEI is still open or in business?
They make a bracket to bolt a vacuum pump to the block in place of factory F body A/C compressor.
Reached out to them via phone and email, and nothing back
Or anyone know of someone else who makes the bracket?

Responding month and half late to this thread. I'm running a GZ motorsports vacuum pump that runs of the tensioner pulley.
Bill is a good guy to deal with.

I think #175 on the rear is to heavy. I put #175 on and I can hardly get the car back to stock ride height. I'd go #150 or lower.

I'm interested in trying a vacuum pump as well. Love to see some back to back track results and Dyno results with and without one.

Very nice! Just got done reading a couple other threads of yours. Was really hoping to see a 10 second thread about your 346 setup. What is done to this ls7? Any dyno numbers? I noticed you said the ls7 injectors were maxed out. Im running those injectors and a 340 racetronix (63psi of fuel pressure) in my 99 z28 and saw 98% duty cycle by 7000rpm when i was tuning it. Its just a 346 with heads cam intake and typical supporting mods. I am kinda confused as to how id be maxing out a 42lb ls7 injector with the setup i have, i know my wideband is good, fuel pressure is more than adequate. Unless some how i am making more power than I should be.

Nice pass OP, what was the race weight of the car on this run?
