A couple of weeks ago, I think it was Don, posted a statement about how to tell if
the Predator you were getting was the Hemi or not. Unless I read it wrong I think
he said the one with the pressed tin VC was the Hemi and the one with the
cast aluminum VC was not.
I have one of each here. The tin VC is number 69730 and the one with the cast
cover is number 60363.
I just watched a guy on you tube the pulled the head off of a brand new 60363
cast cover Predator and it most certainly has a Hemispherical combustion chamber
and flat top piston.

This is in direct conflict to what was posted here.
So... has anyone had their Predator engine apart and can you comment on what you've
found inside????
The 60363 engines are on sale at the local HF this weekend and I thought I'd pick up
and extra engine, but, I don't want to get stuck with two of the wrong or lower power versions.
Like to here soon as the sale is over on Sunday.
Thanks

The hemi valve cover says hemi in big letters and the wedge says ohv in the same big letters. You can't miss it. Bob

Then Bob, why 7 seconds into the video of the tear down of this 60363, which clearly show
the head off the new motor, does the VC have, in big letters, OHV???

My understanding is the cast valve cover is hemi, the tin one is not. Mine is tin and not a hemi.

I'm still learning Bob, think it might be possible to swap
heads? And maybe when they first came out they had
the VC's embossed "Hemi"?

My son just told me that he sanded the ohv off and painted the hemi on there, so I owe you an apology for the miss-information. He is a sign painter and pen striper.

Shame on him Bob!

No pollogy necessary on this side of the border Bob, just seeking to
keep the information straight so some other guy doesn't have to
run around for two days and put 150 miles on his truck making sure
he's got the best.

And is it the best??? A hemi has always given better performance in
any engine and I don't see why it shoudn't in one of these small engines.
but.....I've read several reports that there is very little difference in
performance between the wedge or hemi. I also read where you can't
take more than .040 off the head because the valves hit the piston.
Apparently they never heard of notching the piston.
As I posted a few weeks ago, I can't believe the prices that the
karting vendors get for their engine mod parts. Pistons and rods
are more then they are for a full sized SBC.

I will have to look at mine again to verify the vc,but if you pull the vc the rockers are straight which is not a hemi and the off set like the one in the video is a hemi.This is the difference which I was told by SR racing and I have a non hemi flywheel new in a box.Both motors I have are Hemis,I havnt looked at them since I got back from Tieton last year,I may have that reversed about the vcs
