Thanks alot.

Very cool.

SFI bellhousing arrived today. Very beefy and heavy




Backing plate seems to be about the same thickness as the adapter plate. Since it won't fit behind the flywheel AND over the adapter plate, the plan is to copy the adapter plate bolt holes onto the backing plate, then ditch the adapter plate. The backing plate will also need a hole drilled for the starter but I don't know yet if I'll need to clearance much of the bellhousing for the starter. IIRC it will fit a 168-tooth flywheel which I think is larger than the LT1 stock flywheel. If the bellhousing has a larger diameter inside than the stock one, I shouldn't need to clearance it much for the starter.

Unfortunately, I probably won't have time to work on it at all until next Wednesday. I did get a bunch of wiring done over the weekend though.

Finally got around to putting my braided hoses together:

Fuel hoses; return line comes from the schrader valve for now to the FPR




Oil drain


Oil feed from beside oil filter

And picked up a turbosmart boost controller for $20. I'll probably upgrade to an EBC later.


Hopefully I'll finish up the engine part of the wiring over the weekend.

Thanks Dave been following that thread also His is an all out racer. My sheer lack of sleep made me miss the pulley altogether

[ericjon262]

they're easy enough to swap with the engine in the car anyways..

In that thread it looks like the ATI balancer doesn't have holes for a 4-bolt pulley... I don't think I'll be ordering one for a while anyway.

[Superdave]

gotta be RWD only, the FWD balancer is also the pulley. You should be ok if the wheel is welded to the pulley.

you may want to check this thread out, he used one. http://60degreev6.com/forum/showthre...fters-with-2-8

I know they sell certified blankets for autos. Haven't seen any for manuals though

That blanket is meant for the trans housing itself and not just the bell housing. TQ converters typically don't blow up like a clutch/flywheel does, but the Auto clutch pack can explode in the same way, hence the blanket for the trans.

saw balancers were mentioned, this is the one i almost bought for mine... http://www.summitracing.com/parts/at...make/chevrolet

If i ever convert to an internal 7x trigger i'll probably get one, right now my trigger wheel is bolted to the stock balancer.

I was looking at that balancer as well, but its listed for FWD and RWD cars so I wasn't sure which its for. Also, my trigger wheel is welded to the pulley, so is that an issue? Do I just need an SFI balancer or the whole balancer/pulley assembly?

Why not just gt a blanket instead of a custom bellhousing? MUCH MUCH cheaper.

Because some rules specify a Certified Bell housing and not just a blanket.

[unchained01]

Are those balancer used on a fwd setup. Or is it for rwd 3.4 ? Just curious
