Flywheel & Clutch Sizing

[Clarmo]

I'm taking the 3.8L power-plant out of the Taxi and swapping it with a new 350 Vortec, Mild cam, roller rockers, 650cfm Carb, Headers...And I'm keeping the stock 3 speed manual transmission and Stock 2.73:1 gears. ( but installing a posi carrier )
I'm getting some parts together now and I'm looking at Flywheel & Clutch options.
My question is: Will a 168 tooth flywheel and 11" clutch fit in the stock bell housing?

Thanks,

what bell housing are you using?

I'd personally drop the rear gear ratio. Will help that 3 speed survive behind that 350

And I'm thinking you'll need a 153 tooth flywheel and matching starter

The original one.

When you say drop the ratio...do you mean increase or decrease the ratio?
The transmission has a 3.5:1 first gear ratio so that compensates for the 2.73:1 rear diff ratio.
It gives me a final drive ratio of 9.555:1 in first gear.
Like having a 3.73 and a TH350 (2.52 first gear ratio) gives you a 9.4:1 first gear ratio.
The only options I've found for the later model 5.7 vortec, externally balanced flywheels, are 168 tooth flywheels.

I'm not Racing this car, that's what the orange one is for in my profile picture.
The Taxi is just a street cruiser (that I'm going to play around with 😉)

Get a TBI 305 flywheel. And go to at least 3.42s

do you know the part number of the bell housing?, that will tell you if the 168 tooth flywheel will fit. Why do you want an 11" clutch?

Racing or not I'm assuming you're planning on dropping the hammer time to time. On a 35 yr old trans that was weak to begin with that's all it takes
