That's what I was afraid of.

Has anyone ran three spoke rear hubs with a 8 x 8 rim. They are 3 on 5.25. A local jr dragster builder has some sweet beadlocks I'm wanting to run but I'm not sure if the hubs are as strong.

Sounds good Jeff, I'm going to try one. I do have the ec roller rockers already.

Hey Jeff, what do you like more on the EC cam over the cheetah?

The was brand new from briggs and I'm not sure of there sleeving procedure. When I get some time all do some measuring. I think I'll have the machine shop take the lip off the piston which will make it a true flat top and we should be good, but got to do some measuring first.

Thanks George!

George, do you guys sell the thicker copper gaskets? Looked on the site and it didn't say how thick they were.

I'm wondering why it's hitting so much more on the one side.
9  Engine Help / Briggs OHV & Vanguard / Re: Piston Clearance on: October 12, 2014, 04:56:05 PM
How much clearance did you have between the piston and head?   Also what was the piston to wall clearances?

I didn't measure either one, I'll have to put it back together and check that.
From what I am seeing its touching all the way around it. One side maybe a hair more but its all the way around. First off Most stock applications the piston will sit .020 below the deck. These rods tend to put the piston flush with the deck. A gasket once installed is usually about .032. Under load and high rpm these rods can stretch as much as .030. Thats why I have always said .030 minimum between anything moving. Now if this .030 stretch is happening then your only have a .002 safety margin. Not enough in my book. What you need to rectify this is have a .035 to .040 thick Copper head gasket made. But if you look close you will see the piston lip in the carbon on the other side of head. Now you can take roughly .010  maybe a couple more off the piston and fix it also

Thanks for the info George. I'm going to put the short block back together and do some measuring. I figured with the stock gasket I would have plenty of room.

Ok guys, got a problem I haven't had before and it has us stumped. This engine is a Briggs 33 with 10 races on it. Pulled it apart yesterday to freshen it up and the piston has been touching the head on the spark plug side. It has an ARC rod and stock piston, I wouldn't think the rod stretched but if it did I think the piston would hit all the way around not just on the one side? Maybe something went wrong with the piston? Any ideas??

Thanks for the info. Will be thinking on this one.

My Cheetah pulls great off the corner but just seems to die out halfway down the straightaway.

Hey guys, I'm curious to here from someone that has ran a Precision Cheetah cam in a single briggs and then ran the EC billet cam, http://eccarburetors.com/store/en/precision-mower-accessories/mower-engines/model-28-ohv/model-28-ohv-performance/billet-cam.html that they have on there site now. I'm currently running the cheetah in my 33 ohv but I'm considering changing to the EC one. Any opinions?

Sure wish this was one weekend earlier, I'll be down there for the drag races.

Don at G-Team balanced my stock 33 avs crank and did a great job.
