12 Valve Cummins Q&A 

Great video! Love how you guys don’t just lump “p-pumps” into just one group. No other videos I’ve watched have explained the difference.

First time listener today and this is my 5th video. Hugely underrated channel! Thanks for the educational info!

I absolutely love what you guys are doing with the 12 valve stuff!!!!! Keep it up!

A tech video of adjusting "tip in" would help probably 80% of P7100 owners.

Always awesome to watch this kind of class Lenny, thanks a million…

This was great! Please continue to do more of the same.

Good stuff 🙂

Keep up the good work, us 12valvers appreciate it!!!

My first gen Intercooled made 400+hp from 1900rpm to 3300rpm with an s300g 4" exhaust and powerjet stage 2's. I firmly believe in normal street driving it would walk away from most 600hp 12v p pump trucks.

whats your thoughts on afc live?

Please do a deep dive on 1998.5-2002 24valve vp engineering

I love this shit. I feel like so much of the 12 valve info out there is so old and outdated and now it's inaccurate compared to what you guys are doing. I'm building an 83 crew cab dodge with a 215 pump 12 valve right now and once the truck is on the road and ready to start making power, dynomite eill be my only stop.

What about the ve pumps

Please do this again next week! I bought the short wagler rods, 6.7 crank, and stage 2 head. Now I'm looking for time to put it together.

How about afc live with max rack travel , and 4k gov springs, 160 pump, stock 97 inj. I pull all the time. Also °16 timeing. 055 delivery valves. Thought about power driven stage 2 power jets.

I am about to dive into mods on a 94 p pump motor with 48k original miles. Currently in a Rv chassis. I have some serious questions. Whats the best way to contact you guys.?? Love the info and the channel... I'm a gas wrench. Still learning on diesel side. Thanks from Oregon.

Can I get my stage 4's upgraded with pilot holes?

Are you going to sell the 12.5 plungers and barrels as a kit?

I’m on that page and I answer or forward to you

I absolutely love what you guys are doing with the 12 valve stuff!!!!! Keep it up!
