Thinking about upgrading from the hotcam...
Thinking about upgrading from the hotcam... Current Engine Mods:
- Stock 63k mi bottom end LT1
- Manley 2.0 intake/1.60 exhaust valves, Crane 10308-1 spring kit,
- GMPP Hotcam
- GMPP 1.6 ratio aluminum roller rockers
- Comp Cams hardened pushrods
- Cloyes double roller timing chain
- Hypertech 160 deg t-stat
- CSI electric water pump
- March 25% underdrive pulley
- 1LE a/c delete pulley
- Lucas/Delphi 42 lbs / hr injectors
- Walbro 255 lph fuel pump
- MSD Blaster Coil, new MSD opti cap/rotor
- Taylor Spiro Pro 8mm wires, NGK TR55 plugs
-(Flowed 249 intake/162 exhaust, 11:1 compression) Heads milled .010, .026" gaskets
I'm wanting to go with a bigger cam that is still good for driving on the streets. The car is a m6 and also has a Moser 12 bolt rear with 4:10 gears.
Would a 232/240 .592/.592 112 LSA custom grind work for me?

Will the GMPP 1.6 rockers support .592 lift? Will a cam only upgrade be worth the effort for the HP gained over the hotcam? Might be better off going with a H/C from AI or similar.
I would not be using SELF ALIGNING rockers with lift values that exceed 565 lift....
I would also recommend stepping up to 7/16 studs, guide plates,hardened pushrods and 1.6(7/16) nsa rockers along with a custom cam from LE or AI
