bootlegger lunati?

[Grumpy]

I have been noticing the add for the lunati bootlegger in super Chevy magazine. Other than the page in the magazine I have never heard anything good or bad on this line of cams. I am wondering if this is just a lunati version of the comp cams thumper cam? Is it just a make noise cam or is it something different? I just remembered the add says something like all your neighbors or friends will hear you coming.

108 LSA 104 ICL narrow power bands on the hyd flat tappet cams. I'm not a cam guru by any means but they look like what I want to avoid.

love internet wisdom like that! ,
yes its true UP to a point,
but ever ask yourself ,HOW MUCH,narrower?
and narrower compared to what?
will it hurt or help my current combo?
at what rpm range, will it effect my combo?
OR UNDER WHAT CONDITIONS?
will my particular combo benefit?
do the results change if I select different heads?
change headers? ADD compression?
yes, effective cam timing, when correctly matched too,
increased compression and increased displacement both,
have a very noticeable effect on the engines low speed torque curve potential

heres the results of a test vizard did changing nothing but a cams LCA

heres a dyno of that cam vs the chevy hot cam with a 112 lca

lets use the chart above to do a few calculations

IF you have a 350 with 2.02 intake valves in theory the result finding the ideal LSA
350/8=43.75/2.o2=21.6 so a 107 lsa is about ideal

IF you have a 383 with 2.02 intake valves in theory the result finding the ideal LSA
383/8=47.875/2.o2=23.7 so a 105 lsa is about ideal

swap to a 496 BBC with its 2.19" intake valve?
in theory the result finding the ideal LSA
496/8=62/2.19=28.3 so a 101 lsa is about ideal

now keep in mind that calculation would in theory maximize the engines power curve but ,
theres always going to be compromises made in any list of components selected, to allow the engine power curve to match the application and gears, drive train, etc.
selecting the correct MATCHING PORT SIZE< COMPRESSION HEADERS<AND CAM DURATION would also be mandatory in every case to maximize the engines potential, and that might result in an engine with a good deal more peak power and torque but rather lousy off idle driving characteristics in some cases making a compromise to a milder cam duration, a bit less compression and better idle characteristic's, and less exhaust emissions and noticeably more street-able
USE THE CALCULATORS to match port size to intended rpm levels... but keep in mind valve lift and port flow limitations
