I like ls3 stuff for versatility. So many options and intake options. Ls7 will
Make a few more HP in the end but aftermarket ls3’s are darn good heads IMO. Fast is shitting the bed by not offering shorter runners for the ls7
An ls3 headed motor with a high ram is ***** of **** if you have the clearance for it

Appropriate Intake.
Guy here in Nor Cal just had a ~440" make 670 RWHP & ~600
Lb' with MMS LS7 Heads, MMS MSD, 12.5:1 Comp not sure if
Solid roller in C6 Z Track Car!
The FAST Composite Tunnel Ram with LLSR Would be
Insane! 700 RWHP & 600+ Lb'!!!

Agreed! Obviously I Love Aftermarket LS3 Heads with LLSR &
Appropriate Intake.

You can use a Holley high ram on ls3 heads to
Make huge HP.
There was that guy on yellowbullet who made 790 hp with a Stock CI ls3 and ported Stock ls3 heads. I think around 12.5:1 compression as well

[QUOTE=big hammer;19855832]The fast tunnel ram looks awesome but what’s it going to fit in lol
I believe the OP wants to fit in a Fox Body and while Im not positive it will
fit, definitely worth measuring to see, similar height to Holley Hi Ram with the
added benefits of Composite Material & 3 different runner lengths.
The Fox body has a lot more room under the hood then a F Body or Vette.
Plenty of Hoods available to fit the Fox as well.
