I'm running Comp Cams Bee Hive 90/252 lb. with titanium retainers and not sure that 95/260 lb. will be enough. My tuner is telling me I may need something in the 130 lb. range to run a boost level in the 27/28 lb. level.
Here is where the cars current mods are as of 11/28.
MMR 1500
Crushed 4.0
custom grind cams
3" mandrel bent exhaust
Mac pro chamber
Stainless works headers
Last dyno was 750/630 at 15 lbs. but when I try and run the higher boost level the valves float.
I've changed, added, and replaced everything I can think of so it looks like springs are my last option.

I'm sure Tooley can find a spring or make one.
But you may be looking at head removal and extensive modification to make them work.
Good luck!
They are not easy to install when the heads are on the car.
I run Manley High Performance 4V spring kit (does not fit GT500) (Manley Part# 221434-32) From MMR
Recommended for all Forced induction applications and aftermarket camshafts, compatible with all factory locks and retainers. Up to .525 Lift 95lbs seat pressure/260 open pressure

At least it's done,& I had no codes or probs going to MV 11 & MV 12
Looks like I may just pulley for low 20's, that should put me some where in the 800's and hopefully 9's at the track.
I will say that since swapping out the stock cams for a set of degreed in custom MMR's and a full 3" mandrel bent exhaust with big flowmasters and a Mac Prochamber the car has amazing low end torque now and it has that angry Cobra growl with no raspy sound or backfires.
Doug you are gonna have one HELL of a cruising monster!!
I wish I could say the same, and hopefully I will soon. I'll be real honest when I say I'm burned the hell out! I tried to work on it the other night after a month of pretending it didn't exist only to have a bad night. I was super close to firing up an eBay add "as is" and move on. Wish I was kidding. Maybe when I feel the Louisville fever quickly approaching I'll pull up my panties? Let us hope.
That is one piece of super Badassery you have. Keep the shiny side up!
