i found a 68 327 motor i plan to buy and build for my z and use the stock t5 borg tranny for now. what am i gonna need to pair these two together? i read about a guy swapping a 78 350 to a t5 and needed the flywheel from the 78 and couldnt use the 86's flywheel since it was to small. what do i need???

 

An 85 Z28 flywheel.
All other parts from your 86 will work.

Make sure that 327 has accessory bolt holes needed to bolt up your brackets too.

 

whats the difference between my 86 flywheel and the 85's? will a flywhhel 85-earlier work?

 

A flywheel from 86 up will not work because they changed to the different bolt pattern on the crank.

A flywheel from 81 back will not work because it will be 14", and won't fit in the T-5 bell housing. This would include the one from a 78. Whoever thought they needed that for a T-5, was mistaken, and in for a rude surprise.

I don't know whether a 82 flywheel will work.

I know FOR SURE a 83-85 F-body V8 one WILL work. You will find there are 2 such FWs; one, which came on the high-perf cars (L69) will be about 16 lbs, the other which came on the non-perf cars (LG4) will be about 22 lbs.

Therefore stick with 83-85.

Be EXTRA DOUBLE SURE your heads have the accessory bolt holes in the ends. Otherwise you will onlt be able to install minor conveniences like .... an alternator .... with $$$aftermarket$$$ brackets.

Also, make sure your block has the 78-up starter bolt hole pattern drilled in it. No starter that works with the 12.8" flywheel will work on a block that doesn't have the bolt pattern for it. Remember that: NO STARTER EXISTS that overcomes the lack of the bolt hole. If it's not there, get it installed BEFORE installing the motor.

 

what size exactly is the 83-85's flywheel? just so i know exactly what im looking for because i dont wanna have to buy extra parts lol

 

Order either the L69 or LG4 verson, say, for an 85 (two-piece rear seal and 153 teeth). FYI, the 86 bolt pattern is different as 86 was the first year for the one-piece rear seal.

im not going to have to drill any new holes out am i?

 

also what starter am i going to need?

 

look and see what starter is on an 85 camaro its either straight or staggerd bolt holes than make sure that 327 has that bolt pattern this so the starter will match up to 153 tooth 10.5 flywheel

 

if for some reason you would want an old 153 tooth fly wheel off of my 85 camaro let me know pay for shipping and you can have it

 

The one for 83-92 F-body manual transmission. For which as described above, you will need to be sure your block has the correct bolt pattern. I've posted why, the pic of the hole, how to drill it, and everything else you could possibly need about it, so many times now that I won't do it again; search this forum for my userID and posts containing "starter bolt hole", you'll get all the info you need.

 

i have a 1985 camaro with a 1978 350 with staggered bolt patteren for my starter...got a 14' 163 tooth flywheel and a lakewood bellhousing for a T5 and not move my starter,,,i kept my big automatic starter and no drilling...hope this helps.
