Anyone here ever use a Lunati 54743?
 

Has anyone here used a Lunati 54743 cam? I have done some searching with different cams on stock flow numbers with DesktopDyno and found that this cam made as much power as most cams recomended on here altough it made it a lower RPM when used with 1.6 rockers.
Lunati 54743 cam specs:
IN DUR - 217
EX DUR - 227
LSA - 111
IN lift w/ 1.5 rocker - .471
EX lift w/ 1.5 rocker - .480
EDIT here are the 1.6 rocker numbers:
IN lift wi/ 1.6 rocker - .502
EX lift w/ 1.6 rocker - .512

No one has looked into this cam before?

I have never heard of anyone using it before though the specs look like it would be perfect for the b-bodies with stock iron heads and a set of 1.6 rockers.

I think the low lift would turn most people away, I am not saying I personally think it is a huge problem just that I think that would explain it's lack of use.

Whay i was looking into it was with the low lift i could use it in combination with 1.6 rockers and be within the limits of the LT4 valve springs. Also, It produced peak power around 5300 rpm (accordin to DesktopDyno with stock flow numbers etc.), and at that rpm it produced the slighty more horse power, and considerably more torque than the 306 cam which also peaked about 3k higher (compared w/ only changing the cam numbers, both with 1.6 rockers). Another thing i liked is according to Lunati's website it is listed as a loppy idle cam even with the lower lift (other cams on their website with more lift were listed as fair idle)
Anyone else have any input?

The lope probably comes from the 111 LSA. I'd still go with bigger springs than Lt4. Not much lift on the exhaust side---the most restrictive side of the heads. I like the duration numbers, but would like more lift, especially on the exhaust side. Don't ask me why.:cool:

The HP peak will be higher than 5300, the software is probably not setup to recognize the way the ultra short LT1 intake runners move the powerband up compared to the same cam in a gen 1 motor.
I had a ZZ3 cam 208/221 .474/.510 112 and it peaked at 5400.

The LT4 springs are perfect for 1.6 rockers on a stock cam, and that is about it.

I plugged in the ZZ3 cam and it did make more power at less RPM than that lunati one. Looks like when I do a cam swap thats what i'll go with. Thanks for the advice. Would the LT4 springs work with the ZZ3 useing 1.5 rockers? I don't plan on reving the motor up very much and they are already on the engine.

The nose of the ZZ3 cam needs to be opened up to accept the vented style opti. Very minor modification for a machine shop, maybe $20 but something I felt it important to mention.

I am not sure on the LT4 springs. Need to consider the ZZ3 achives .510 with 1.5s which would be harder to control and .510 with 1.6s because more of the lift is coming from the heavy lifter being moved more to achieve the same lift. The lower rpms might be enough to make the LT4s work. Springs are easy enough to change later if you try it and endup with some valvefloat.

Well the LT4 cam with 1.6 rockers lifts to .525 so i think they'll be ok.
How exactly do i need to modify the ZZ3 cam?
EDIT i have a 94 LT1 with the non-vented opti

It is just having the nose hole opened up to .500" diameter and I think 1" deep. Honestly I would just bring a stock cam and the ZZ3 cam to a machine shop and say make them match.
I bought my ZZ3 cam already modified and before you ask have already sold it.
