On the bottom.
Could it be missmarked cam? C75 similar to FK98?

Take a side shot pic of the profile/lobe. That will tell us if it is for stock or ratio rockers. Best to just plot it with a dial indicator, glue a bolt into an old lifter, put the case half back on with the bolted lifter in place with a dial indicator against it and a degreed pulley in place, no guess work.

cam gear
#1- .221
#2- .415
#3- .435
#4- .430
This was in a 2276 used for drag racing. Looking at the picture with the lifters, the 2/4exhaust definitely has some funky wear.
Motor initially came apart because of scoring on 3#cylinder wall ( wrist pin malfunction)- this was following having broken that rocker shaft on the 1/2 side of motor.
What I discovered in disassembly was that the flywheel/crank dowel pins were sheared off. So much to do.

Thanks. It’s is possible it’s a scat logo. There doesn’t seem to be a better pic possible as it’s just a poor stamp.

That is the cleanest dowel-pin simultaneous shearing I've ever seen. Very Happy Seriously though, that almost looks "fun" to try to fix.

That's what I thought. Hardly hurt the crank surface.

Send it to Modok. He will dig them out of there, and it will be just like new.

I believe I’d like to get it fixed, yeah.

How can we make that happen?

Anything can be fixed. It would probably be cheaper to get a new crank.

Not really. DPR pulled the dowel pins from my crank over the summer. It wasn't too expensive at all.
Cheaper than a new crankshaft.

I'm sure that Glen can do the deed as well.

Yeah. I saw that, too. So I was a bit surprised to get the response I did. I dunno. Maybe something has changed there.
