Danno74Z Posted September 1, 2007 Share Posted September 1, 2007 I'm getting ready to purchase a clutch flywheel package for my LT1 T56 project and would like some recommendations. I have a custom bellhouse and HTB that can accommodate either the 153T/12.75" flywheel or the larger 168T/14" flywheel. GM Performance has three flywheels that will work in my setup. They are: 14088646/153T/16LBS/$262, 14088650/153T/~25LBS/$239 and 14088648/168T/30LBS/$172. Would anybody go with the 168T 30LBS unit? If you want to add some clutch suggestions throw them in too! Thanks, Danno74Z Quote Link to comment Share on other sites More sharing options...

Guest 350zgto Posted September 2, 2007 Share Posted September 2, 2007 Danno, here's my 2 bits. I have run both the big and little flywheels with 350 Chevys. Benefit to the big flywheel is more inertia to launch a heavy car with a big motor. Not a concern on a Hybrid Z. I have 2 lightweight cars now with the small flywheels, 16 lbs. These small flywheels rev up VERY fast and decelerate VERY fast. I love the throttle response and the braking control to set up for turns. I am using a Centerforce II in my 350ZGTO. E-Z on pedal effort, grip is unreal, very smooth operation. Quote Link to comment Share on other sites More sharing options...
ezzzzzzz Posted September 12, 2007 Share Posted September 12, 2007 The 153T would be fine. You might consider looking for a 153T flywheel behind a Chevy Vortec V6 with a manual box at a PNP for about $40-$50. It should reasonably light or could be lighten at the machine shop. A new one is great but the price is a bit high Quote Link to comment Share on other sites More sharing options...
getZ Posted September 12, 2007 Share Posted September 12, 2007 I like the smaller diameter just because it gives a little more exhaust clearance. I have an autmatic with a flexplate but it the same idea. Quote Link to comment Share on other sites More sharing options...
Danno74Z Posted September 12, 2007 Author Share Posted September 12, 2007 getZ, ezzzzzzz Just a couple of days ago I went up on Craigslist and got a brand new 14088646/153T for $125 (I made sure it was new and not turned) Still in the Genuine GM part box. Guy had to abandon his project. This flywheel is 16lbs - VERY NICE! Thanks for your input. Danno74Z Quote Link to comment Share on other sites More sharing options...
