We changing from a Turbo 350 to a 3 speed manual. Looking for a light weight flywheel, some are 153 some are 164. I belive our flexplate is 164. Will we have to change starters for a 153? Any other problems in changing. Also looking for a light weight clutch assembly (can't use a mini-clutch) with out spending a fortune. Any ideas??? Also does any one make 6.0 gears for a 7.5 10 bolt GM rear end? Thanks!!!

You will need a 153 compatible starter. I didn't feel like chasing a bunch of mismatched parts and bought a RAM clutch lightweight flywheel setup. 10,000 RPM makes one too. A lot of racers just run a corvette flywheel and clutch setup from 1968-78 or so.

Check with your Chevrolot Dealer, ask for a corvette flywheel. they are about 17lbs and will work with a stock clutch and starter. Oh yea, they are about 200 bucks

MRRacing has great prices on used stuff. If you want new, check out Speedway's price on the Ram nodular flywheel, $150. BTW, you can get a mini-starter with both 153 & 168 starter positions. You might want to consider a Vega set-up if you're not gonna run a super hi-horse engine. If I recall correctly, the complete Vega set-up weighs 27 lbs, versus 34 for the Vette/Camaro/Firebird. You can buy the clutch, pressure plate, and throwout bearing for both set-ups at your local Autozone for $100-$125. Tell 'em '75 Vette or '75 Vega. I've used both, and you can really tell the difference over stock. I've also used the 10,000 RPM "stock appearing" set-up(17 total lbs), but it's kinda pricey. Let us know what you decide, and how it works out for you. One more thing; the bolt pattern changed on the crank sometime in the mid-eighties. I believe it got smaller when they introduced the one-piece rear seal. 3" bolt pattern on newer stuff, 3 1/2" on the older stuff.
