And we have a winner I hope u stop right there lots of flow for a small valve 😊😊😊😊

🔔😎 Ancient technology vs 3-4 bar reminds me of the lipstick joke. 🤔 Or was it the silk purse.

High $$ valves It’s going to be interesting.. You need them though for strength and durability? Right Dr. Chucky?

[@servediocylinderheads]

@@ElvinLeadfoot Chucky? Yes.

[@jseal21]

Maybe it's just the perspective but the margin on those exhaust valves seems huge. Super thick, no???

[@servediocylinderheads]

@@jseal21 Machined down from 1.6" to 1.545"

[@jseal21]

@servediocylinderheads Ohhhhh 🤦‍♂️! You said it like 25 times and I didn't stop and think about the effect that would have on the margin. Carry on, I'll remain in the peanut gallery.

[@servediocylinderheads]

@jseal21 No problem!

[@daleanderson7629]

Could you please show how shrouded that intake is through its lift range. Would be interesting to get a feel for how that is effecting everything. In a high revving engine is it better to give up a little static compression for flow vs a lower revving setup. Thanks for sharing your work

[@servediocylinderheads]

@@daleanderson7629 A very good question. When I was young I cut the chambers hard for extra flow and swirl. Check out my fuelie videos. They worked very well. They were also street stuff limited to 7000 rpm. This is a bit different and I want to keep the chamber tight for compression. Thanks

[@rolandotillit2867]

~335ft/lb @7,200rpm or about 460hp as it is right now. You pick up a little on the exhaust and intake, and you'll be right on the cusp of where you wanna be. I feel I need to clarify, I'm not talking about crank horsepower, I'm talking about at the ground. You generally lose about 60hp through the transmission, prop, diff and axle shafts. I'm actually generous when it comes to at the wheels, it would probably read a little lower on a hub dyno.

[@servediocylinderheads]

@@rolandotillit2867 I was talking crank. Thanks

[@rolandtamaccio3285]

I'd put an eighth inch plus radius on that exhaust margin ,,, !

[@servediocylinderheads]

@@rolandtamaccio3285 I agree. I will test it on an old Chevy valve first!!!

[@No1414body]

256 could for 530, need alot of work on that intake

[@servediocylinderheads]

@@No1414body No kidding!
