Then it’s this one below, correct?

The dome fits? I have smaller some slugs that barley squeak in. I do not see that dome fitting. I’ve also not held them in my hand ether.

Yep, the dome will for W5’s. You just have to mill the quench pad down to zero deck if you had it above the deck to start with.

I should have mentioned that you have to make sure that you understand when you mill that quench pad off you are effectively putting the dome that many thousandths into the chamber. That raises the compression quite a bit.

I know because I was shooting for 13.5:1 and milled .020 off the pad and ended up at 14.8 or something.

Thanks for the tip.

You gonna run methanol?
 
You still have these by chance and maybe want to sell them?
 
That was the one single biggest draw back and sales inhibitor of what was otherwise an excellent corporation backed racing part supply effort. MoPar had some of the best equipment and designs of there own parts. The hefty price tag on some of the other parts was insane. I don’t understand over charging (and by a large margin at that!) the very people using and flag waving your product!
I've noticed that no matter what part is mentioned, mopars have been and still are more expensive to build than a Ford or Chevy, rather stock rebuild or high performance good ol mopar equals more money.
 
It's a quantity thing.....
Furds & Chebbies are more popular, more parts get made, unit price comes down.....
 
You truly want pricey? Build a;

Cadillac
Buick
Oldsmobile

Middle of the road are MoPars, Pontiacs & AMC’s.
Cheap, Chevy and certain year/model Ford small blocks
 
I always thought MP advertised those as 12.5. I know it's easy to get that with um.

Good friend of mine that I am helping at the strip is running a Cadillac 500. Sweet car. I'm his main hands-on engine guy but it's a GM so it makes my skin crawl LOL. Nice guy and one hell of a build that I don't want to know the cost of
