Real world Hughes Steamroller experience?

Hydraulic Roller Cam. Great performance cam in 340+ c.i. applications. Works well with computer modifications or increased induction systems. Likes headers and 3.42+ gearing.
Part Number: 20200715
Badaboom you got it!
the events are
264intake/270exhaust/122 compression/107 extraction/43overlap, in at 106. and 58* ICA , and the 112 LSa is more suitable to the 904s ratio splits when using smaller stalls. But the 51 degree ramps from advertised to .050, are more suited to a hot streeter. Quiet and long-lasting, but sacrificing overlap and extraction, the latter which is not a big deal in a racecar. And for you, the 43* of overlap seems more in line with your mild idle requirement, altho the 340 Mopar cam had 44* and you could always hear a 340 on the parking lot, back in the day.
So, all-in-all a pretty good choice......... IMO .
But since you asked about the steamroller, lets compare them side by side
260/272/125/111/48 overlap; in at 105-ICA, steamroller.
264/270/122/107/43 overlap, in at 106.Lunati 715
So;4 more intake degrees is about a half a cam size, or 10 hp, maybe 12
The exhaust is a wash, both adequate.
The Lunati at compression of 122vs 125,loses some cylinder pressure, perhaps 4 psi
The Lunati with 5* less overlap you would think will idle with a lil less lope, but in fact with a lot less. This because the exhaust actually closes 6* sooner, because the Installed center Angle of the Lunati is speced to be 106* as a way of maintaining the cylinder pressure. If you actually installed it where it maybe should be at 110, the numbers would be;
264/270/118/111/43 overlap; in at 110 Ica; Lunati 715
260/272/125/111/48 overlap; in at 105-ICA, steamroller.
As you can see compression is down to 118*, 7* less than the steamroller,so for a streeter this will not work at 8/1; no how, nor with the factory stall TC. But the exhaust now closes where it should and the overlap period is optimized, and with a closing point now within 2* of the steamroller, it's gonna idle sorta like the steamroller.
The penalty is, that the engine will require an SCR boost to recapture the cylinder pressure to maintain lower rpm driveability and midrange power. The more effective overlap might be good for a few more ponies as well,with headers.
So in a race car with a hi-stall, it WILL work, sacrificing only a lil midrange power, but the upside is more operating rpm and more effective overlap, so more absolute power at the top. But then, with a hi-stall...... you wouldn't need the 114LSA anymore lol.
And, of course, if you brought the Scr back up, you could pump up the midrange power a fair bit, and so reduce your stall some, if you wanted to drive it on the street.
