i had the gt7 cam with my 370/mp112. 208/230 .59x 121 it was kinda dead in the middle range...maybe due to having a heavy truck. i think the gt2-3 might have been a better choice at the time.

my 224/228 .600 114 was much better. pulled hard throughout the range and sounded good, too.

i have 224/230 .595 116 now and it was awesome with my tvs1900 tons of midrange and pulls hard.

 

I think the GM LS7 & LS9 will not work with our style of engines(99-06) engine because of the cam sensor setup are different.But I'm not an expert.Somebody must know 100%.

I also thing the 122.5 & 120 LS is not as good as a 114-118 range for a F/I .Also that EVILGMC just gave us his experience with his setups that he tried so far.

 

you'll have to end up getting the LS2 timing cover conversion kit to make the cam work i believe...

LS7 Cam, Part Number: 12571251, dur. @ 0.050” I: 211 / E: 230, lift w/1.7 rocker I: .558 / E: .558, lobe sep. 121

Note: Straight from GM catalog, Stock LS7 camshaft will not work in a Gen III engines. Max Lift with 1.8 rockers .591 / .591

Of course the notes from the GM catalog means that it is not a direct fit, but does not take into account the option of switching to a LS2 timing cover/sensor and the required matching timing gears. And just the same as when performing a Gen IV swap into a vehicle originally equipped with a Gen III, one would need a camshaft position sensor harness extension.

Also, I don’t know if there is actually much performance difference between the GT-7 and the GT2-3 when in a comparable equipped vehicle, as kysilverado and I run very similar times, both of us having LQ4’s, ECSB’s with each one of having one of the cams listed.

 

Thanks for clearing this up.

 

Less lobe separation with forced induction means you blow your intake charge right through the cylinder...there's a reason 118+ LSA cams are called 'blower cams'.
