Please keep the p pump content going. LOVE IT!!!!!!!!!!!!!!!

Ohh yea! Love the 12 valve tech and all the pump talk with the differences in pump plungers, cam, ect!! Keep it up!!!!!!

That is one minty 12 valve body and paint in that truck is amazing

Lots of good data and testing, thanks for sharing!

Would love if you did some testing on AFC live show adjusting

So I went with 3-4k governor springs and when I was in it I noticed one side had 1 shim and the other side had 2 shims. I finally tracked down shims out of another pump but I'm thinking of doing what ya did, pulling out the thin shim and giving the springs an extra click and bringing the idol screw down to keep it from jumping up to 1800 rpm while I'm parked 😅 down to and 750 to 900 while parked and a/c going.

Thanks for featuring the 12v content! Why no AFC Live?

🔥🤙🏻🇺🇸

Awesome job and video Lenny… quick doubt about gsk, you’ve removed a shim and add 1 extra click… how many total clicks? 5? 1soft + 4 hard clicks?

What supply pressure are you running? I've heard they like a lot of pressure. And what did egts hit on the final pull? I'm running a 160 pump (gutted afc no plate, I know I have wanted to fix it) 191dvs and 5x.014s, 60+ psi supply on my 12v in my 94 gmc with an he351 with a 475/83/1.10 and am wondering if I'm leaving a bunch of power on the table. Egts will go as high as I let it, drive and boost are about 1:1, but I'm also running 60/40 waste motor oil which runs it hotter. Need to play with my gov springs some, I have to barely touch the throttle for it to start and at low speeds low throttle it will sometimes start bucking.

I have had 160 pumps with the non reversion cams and flat top 12 plungers that would smoke a 913 pump with those retard notches.

Didn't you run into this before? Guy brings in used truck thinking he's got a 215 yet you guys can't time it correctly. Come to find out it's a 160

Do u guys dial in other other people's 12 valves? Lol
