Hello Brent,
Any particular reason for the 123 degree ECL?
That very very early exhaust opening with that ECL will result in torque loss.
I guess that might be the trade off for high vacuum requirement the customer has?
Anyhow - I love these builds.
Is the HP guess un corrected? Or corrected?
Not Brent, but I am not sure the ECL has the effect you think it does. Saying the early exhaust opening kills torque, can be correct in an academic argument, but a quick peruse of the dyno forum will show many of Brent's (and mine for that matter) That 445 should be a monster
I would assume Brent has a vacuum and/or idle requirement, that's why I do it when I have to
Some examples of mine, all in the dyno forum
461 all iron, CJ carbed - LSA 114 - 237/237 - 106 ICL - 536 ft lbs, 520 HP (15 inches of vac)
461 TFS head PI carbed - LSA 114 - 235/237 - 106 ICL - - 577 ft lbs, 568 HP (16 inches of idle vac)
461 Victor single plane Victor EFI truck engine, on carb - LSA 112, 230/236 - 106 ICL - only 9.75:1 - 554 ft lbs, 490 HP (at 5000) Didn't take vac readings
I agree in general you don't want to waste the power stroke with too early of a exhaust opening, but you are also gaining on the other end with better cylinder fill and little chamber dilution and good vacuum. This 445 should be a nice mellow monster
