which flywheel/clutch combo to use

Hey I just bought almost all the parts I need (just need flywheel, clutch, and bellhousing) for a t-5 swap into my 86 auto. Its a 305tpi and I was wondering does the number of the teeth matter? At summitracing.com, I can either pick 168 or 153 th flywheel. What is the correct size flywheel my engine?

Also, I also don't know what size clutch to use? 10.4, 11

I'm alright at driving stick, it'll come with time but can anyone recommend a decent clutch, better than stock?

Anyone have bellhousing/flywheel, let me know thanks.

you have to get the 153 tooth flywheel. the 168 tooth doesn't fit inside the bell housing, also the starter is different for each. I bought my flywheel at Advance auto for like $60something

I think its the 10.4" clutch

Ram and Centerforce are popular aftermarket clutch brands. I've heard good things about the Centerforce dual friction clutch.

does your engine have a 1 piece rear main seal? I have a flywheel for that

the 168 tooth is for motors with a 400 crank.. i have one for my stroker and i had to get a bellhousing.. simply doesnt fit in the stock bellhousing.. and i would recommend the centerforce dual friction clutch.. i have one on my TA and it has never slipped.. even on slicks.. also has a lighter clutch pedal feel..

Yes I just looked up on another site, that its a one piece rear main seal. How much would you let that flywheel go for. Obviously less than $60 (brand new)

Do you have the correct flywheel (153 teeth)? Can you send pics of the wheel,bell and clutch(10.4in)?

not true. Either size flywheel is available for external or internal balance motors. I run a 168 in my car with an 11" clutch. My scatter-shield doesn't care either.

He's right. I'm also running an 11" clutch and a hays 168 tooth flywheel behind my internally balanced 355 in my 69 camaro. I did have to get the starter for a 396 engine to work with the larger flywheel and different bellhousing when I upgraded from a 10.5" clutch to the 11". The 396 starter had a smaller nosecone than the 350 starter, just like the T5 starter's nosecone is smaller than the 700r4 starter's nosecone.
