Bruce,

Thanks for the suggestion. I looked at their site and they do have a clutch disc for a 289, but did not see a complete setup with the flywheel as well.

Jim, my memory stinks more and more as I get older, but I'm sorry if I forgot to email you back with clutch/flywheel recommendations. There are lots of options out there, some a lot better quality than the others.

Which QM combo did you get?

Brent,

No problem, I fully understand the memory stuff and getting older. I ended up going with the street stock with a HTOB and the steel flywheel. I have a sprung disc, as there are times that it is a long drive through the paddock to the grid with a lot of spectators walking around and a 15-20 mph speed limit. I would be constantly feathering the clutch and jerking around with a solid disc clutch plate.

Being that every few years I have to replace the clutch, I figured that I would try something different this time. The McLeod that I had worked fine and the disc was going to be down to the rivets in another race or two. I will see how the two compare and let that inform my decision for the next time.

I greatly appreciate all of your input and our conversations.

Jim

Jim,

Thanks for the clutch advice. I'll let you know what I end up with.

Cheers,
Glen

Make sure no organic discs at that horsepower level.

Brent,

Thanks. I purchased the heavy duty disc, not the organic. Should be here tomorrow.

Jim

Default Clutch and flywheel

Greetings,

Well, my Quarter Master clutch, HTOB and steel flywheel arrived yesterday, along with a new Lifeline fire system. The clutch, flywheel and pressure plate arrived all bolted together and since the engine is going out for a refresh and it was freezing in the garage, I decided to use leave it altogether for now.


They looked nice nd the HTOB has a nice feature in that there is a locking stud that prevents the HTOB from spinning on the shaft during install. My McLeod does not have that capacity and the HOB's do spin a little when you are trying to line up the input shaft with the bushing and bolting the transmission to the bell housing. Always wondered if my depth was correct after the transmission was installed and there was no wy to get a micrometer in there.

I did test fit the assembly on the input shaft to make sure that the correct disc was in the package and it slid on nice and tight (but not too tight).

Jim It looks like the flywheel in O balance. So that makes me wonder what you have for a crank in the engine? So I assume you have a 289 stroke steel forged internally balanced crank in your engine. What brand of crank are you using? Who did your motor?

The engine was most recently built by Fitzgerald Brothers in CT, they did the conversion to Webers. The crank is an original that was magna fluxed and machined so that the internals were balanced.

I was going to use Brent for this rebuild, but you scoundrels have so tied up his time that he would not be able to get to it in time for next season's race schedule. I have found a local engine builder who I will be working with, he has built race engines and after having numerous discussions with him I think that it will work.

At the time of the original build I was going to go with a forged steel crank, but at that time they were out of production. The current build just told me that he has found someone that is making forged steel cranks for a 289, not cheap, but given that I am not spending $1,000 to ship the engine that does free up some cash. He was going to take a look at the existing crank to see how it looked before deciding on whether to order one, but I am starting to lean towards getting a new crank irrespective of how good the old one works just because of increased longevity.

Things are starting to show up. The Dart block arrived yesterday. It is quite beefy. The main caps are substantial. A lot of machining to do on it. I have the heads and am getting ready to ship them out and have them ported and flow tested, the engine builder has a full machine shop, but does not do heads anymore.



Parts are hard to come by with businesses having been shut down for a while, hopefully I will be able to procure everything that I need.
