I am considering a cam with about the same duration for my new motor. I think the 13 CR should be enough for that cam (more might be better), mine will be 13.4 so it is close to yours. I do have a 3 speed trans so I am going for more hp rather than midrange torque. A good race car has 5500-6000 converter anyway! LOL My old motor had more torque than it needed any way (279/287 at 0.050 cam).

With you installing it at 105ish with 112 LSA that is advanced plenty, I might have only put it at 109. Let us know how the PG does at the launch. Didn't you have a little less CID last year?




The nice thing about the the belt drive is I can retard it and see if it likes it better than the 104.5 degrees.

Yes last year the motor was a 500 cid so I've increased it 26 cid".

So what's the one thing I didn't check (clearance wise) and none of my Moparts buddies asked me about?

It blew up on the second pass if that helps anyone... Chunks of piston made their way up to the lifter valley.

I thought you covered it all, at first you didnt check P/V But later you got it. I didnt see a Thrust bearing clearence, and now cant remember if you measured ring gap.

Sorry about the damage.

Edit: I see where you measured both thrust and ring gap. I didnt see a piston to Cyl wall clearence.

Ok I'm old and blind I guess. But I haven't found another post. Point me in the right direction with a link.

The only thing I didn't check, I've never checked and didn't know I needed to, was the crank counter weight to piston clearance.

This was a K1 Hemi 4.15 stroke crank and in the first motor I used it in we cut the counter weights down besause it needed so much weight taken off of it to balance it.

And then when I hurt the motor last fall I had it offset ground to 4.25 and Chevy journals. So with the 7.100 rod and shorter pistons there must have not been enough clearance. It would turn over by hand just fine but at speed it must have been making clearance on the pin boss on the piston as they stretched and the piston let go.

That's my theory right now and until I tear the motor down and hopefully verify what happened.

Pistons are off the shelf diamond 4.25 flat top but with 4.440 bore.

So depending on what the damage is I may put Frankenstein aside and focus on the KB motor but I'm hoping it just got a piston or two and maybe a rod. But I think it also bent a valve on each side.... To be continued.

I guess your pistons skirts goes lower then the bottom of the cylinders bores. Here´s a pict of my CP custom pistons with a 4.25 crank. Besides the notch for the BME rods, they are close to the bottom of the cylinders.


And Wade, sorry for your troubles.

Sorry to hear of the carnage. Hope it's not a total loss. Take care.

Wade, did you get a full run in on the first pass, or did you just do a breakin run?


I have respect for your honesty on the good or bad that happend to your car.

Im about to do the same first run testing. Good or bad I will disclose the outcome too. Some would hide it or disappear out of ego issues. Glad to see your not one of them.
