New Clutch Advise
New Clutch Advise Any advice/experience for a new clutch install?
Im looking at the competition clutch stage 2.5 or 3.
Resurface the stock flywheel? Should i get a specific thrust bearing or anything else while everything is apart?
I put 9,800 miles on my top end rebuild this year. Making about 325rwhp. Best we could get was a 13.51 @ 107mph in 80 degree heat. Most 60 fts were 2.1-2.2 with the stock clutch and 342 gears. I also had M/T drag radials on. 1st gear felt so tall at launch, felt like i was losing half a second right off the bat. Hoping for low-low 13s at around 108-110 with new clutch and cooler weather. Also thinking of 390 gears instead of my 342's. Car is 99% street driven but sees the strip once in the spring and once in the fall.

I put in a Competition Clutch stage 2 (I think it was a stage 2, maybe a 2.5) almost 2 years ago along with a RAM aluminum flywheel. It had horrible chatter until it broke in after about 500 miles, but I've been happy with it since.
Do the pilot bearing (I put in a bushing) and rear main seal while the transmission is out.

GM thrust bearing if possible. You should always resurface the flywheel if you are installing a new clutch. Not doing so could lead to a limited surface area when the clutch clamps onto the flywheel which means it could start slipping and wearing prematurely. Same principle as when changing brake pads.
Gangly, the competition clutch is nothing special its like $280 but has awesome ratings. Next motor build in a few yrs im looking for a 400rwhp 383.
Thanks SSRRR, prob resurface stock flywheel and i will look into the gm thrust bearing. This will be my first. Clutch install.

I had the CC 2.5. for your HP it will be fine. 383 pushing 400 to the wheels, no.
Don't go with a lightweight FW if you street or drag race your car. Typically a FW can be resurfaced 2-3 times depending on how much they tale off each time. Stock Replacement FW's though are pretty cheap

Most likely. I'm happy with the clutch, I just needed to get used to the aluminum flywheel being less forgiving in getting the car moving.
