I got my son to hang out in the garage for a while and do some engine building... This is what we ran into and how we fixed it.. Still more to learn for sure..

OEM 351 C block

Scat after market stroker crank shaft

Bronze Cam Plate

Cloyes indexed timing set

Inovator West Dampener #206


Here we go... I install the Cloyes timing set and find the crank gear is not lined up with the cam gear... I searched online and found that Scat makes a spacer for the Cleveland. Part Number 4-CLEV-SPACER. It says on the bag that it is similar to M-19009-A341C.. I ordered that and installed the spacer behind the crank gear. I put a straight edge on it and find it lines up perfectly...

Install the time timing cover and take out dampener and install that. Grab my ARP Bolt 154-2501... Bolt is way to short... Hmmm

Dampener is 1 inch away from the timing cover..

I measured from the inside of the damper to the face of the crank snout and it measures .630..... This is the amount of the dampener that is not engaged on the crank snout.  

This has been a real learning experience for me. Looks like the crank manufactures do not cast in material for a cleveland only crank.. Thus the spacer....

Anyone run into these problems before?

I measured for pulleys and looks like the bolt face of pump to bolt face of dampener is 3.290...


Thanks Fellas...

I took another look at things and found the ARP washer to be too large of diameter.

ARP washer diameter is 1.965

Inside of dampener is 1.790

I think they make a special diameter washer for their dampener. I will update tomorrow.


I am sure you guys have run into stuff like this but I will post my story as it evolves so it saves someone else some headaches.


PS: My son has been walking past the old Maverick in the back yard for years. Time is coming to take down the fence and finish it for him..

These are not O.E.M. parts.
When it comes to the aftermarket, you need to enter the situation with the thought that NOTHING fits and you'll need to address it all yourself.

Correct me if I'm wrong, but I think SCAT makes that crank that is setup to drop into a Windsor block (with Cleveland mains), and if you put it in a Cleveland block, you need to use the crank gear spacer. Few aftermarket companies make the Cleveland specific crank with the extra spacer machined into the crank because then you would have to cut that part down to fit in a Windsor block. But if using the Windsor type crank in a Cleveland block, you simply just add the spacer.

Yes, You have to add a spacer behind the crank gear. I will add the measurement if I can find it...
