Well, things are almost ready to go back together on the 'maro. Since it's all apart I may as well go with a new clutch. Anyone have any clutch recommendations? The details:

68 Camaro, 327 just back from the machine shop supposedly with 400ish horse and shift points going to be 7500. Muncie 4 speed. This is my fun car, will make a few trips down the 1/8th and 1/4 but primarily fun auto crosses and a track day here and there if I man up and get over the fear of wrecking one of my dream cars and the nicest thing I own when I have many other projects cars that are cheaper and I care less about. Will also have to deal with rush hour traffic every now and again since I do drive it to work up to once a week.

Who likes what? Thanks in advance...

I used a zoom in my 72 Firebird with a 455 and 4 speed. I don't have many miles on it, but it has a nice feel to it. Hopefully I'll put more miles on it this fall/winter. Black interior and exterior with no AC doesn't make for much of a summer car.

I have had many built at Clutch Dynamics for about the same price as a box store kit.

Call them and give them a description of what you have and what you want to do and they will make it for you.

Find a local place in town that does big rig clutches and brakes. They will be more than happy to build you a custom setup.

I had Friction Products here in Tulsa, OK, build a 300HP clutch for E30. M20 clutch on an S52.

clutch/pressure plate/TO bearing/Pilot bearing/alignment tool = $260 and they had it built for me in two days and I kept my money local.

Can't beat that.

Back in the day I had a local clutch shop in Tampa do a custom clutch for me. Worked out well. I think that should be an excellent way to go.

picked up one from eClutch on eBay it has worked out well so far, in fact putting one in the CMC car as well

Hmmm, what is everyone's thoughts on flywheel weight? It does need to rev so that is one plus for a light one. Also street driven so there's a plus for like a 30 pound one. Not sure which way to go. Reading some other forums has just confused me more.

Id say really light flywheel, sticky tires and a really grabby clutch, just for fun!

Lightest flywheel you can get. You're a car enthusiast, you can get a around a touchy clutch and loud gearbox for improved performance.

Especially for a car that you won't drive much but for fun.

In reply to Xceler8x:

Oh no, let me correct that. It will be driven multiple times a week. It's just that every time I will be driving it, I will be having fun.

most of the light weight SHOULD be offset by low rpm torque, making it easier to drive than say, a CSP miata with a 10lb clutch/flywheel combo!

I vote, go light!

Is there any other way to build a non towing street car?
