What is your opinions on the holley systematic 2 performance package it comes with heads, intake and cam??? does anyone havve this?? how will do u think it will perform??
I was thinking about that to, it seams like a pretty awesome deal, but you never know if its really worth the money until you hear from someone that has it. seams pretty sweet though
Do a search this has been brought up many many times...
Holley has revised the cam and heads and intake a few times since the begining and alot of the issues have been solved.
With the kit I went 12.60 @ 108mph, bad heads...24# inj, 76mm C&L, 65mm TB
New heads from Holley Warranty Replacement and I swapped to a N-61 cam, 30# inj, 80mm Pro-M, 75mm TB and AFM 4" Power Pipe went 11.80 @ 115.8mph, would have went faster with more gear only trapped 5200rpm instead of 6000 where I was making peak power. Added a 175 shot and went 11.11 @ 130mph, picked up 30mph in the last 1/8mph.
I think more power could be made with a AFR165 or 185 (if you don't have stock pistons) a custom cam, and either a Holley or RPM II.

The first heads I had from Holley had bad guide, they have since fixed that issue with the new head design although you always need to check the valvetrain geometry.
The N-61 is from www.andersonfordmotorsport.com, I also went to a 75mm TB, 30#inj, 80mm MAF and a AFM pipe..this allowed me to go 11.80 @ 115.8 on motor.
I suggest 30# inj, 70mm TB and a 80mm MAF, Holley offers 2 different cams, 1 is emissions legal, 1 is not (the one people complain about is the non-emissions legal) and if you want to swap cams www.flowtechinduction.com
