I am looking for the dimentions from the centerline of the crankshaft to the centerline of the camshaft on the SL6. I remember seeing something of a blueprint in the mopar chassis manual, but I can no longer find mine.

I have a bare block. How exact do you need?

With 4 measurements, you can figure it out exactly......................


(cam and crank bore, inside/inside & outside/outside between the two)

If it is any help, it is the same distance as on Mopar BB and Chevy BB.

Hi guys, I was hoping for more along the lines of "x" inches up and "x" inches left. My plan is to make a "block true" that will allow me to square the deck in relation to the crankshaft centerline. I know I saw some measurements along these lines in the chassis manual, and I have completely torn my house up in search of my copy!

If you want the cylinder deck square with the crankshaft why aren't you using the main bearing saddles as your starting point? The camshaft position has almost nothing at all to do with the relationship between the plane of the cylinder head deck and the centerline of the crankshaft.

Yea, you are right Josh, but that only applies for the lengthwise "squareness". What I want to make will square the block the other way ( deck is not higher on oil pump side than freezeplug side). usually at the machine shop, the block is always square lengthwise with the crankshaft, but the "side to side" is set square with the existing surface. My plan is to make a fixture that uses the camshaft bore to locate the "side to side" and then have a truly square deck surface. Hard to explain with typed words, my use of "crankshaft centerline" in my previous post was incorrect. Josh is right, you do use the main bearing saddles to locate the lengthwise of the deck to the crankshaft centerline. What I want is a fixture that uses the crank and camsaft positions to square the deck the other way.

Ill let the pro's describe it ! :

I get what you're after. If the deck is tilted the cylinder bores won't be square to the crankshaft if the deck surface is used to locate the boring equipment. I believe the original block machining equipment used the oil pan rails to locate everything else. I'd start from the pan rails and measure to the main bearing saddles to see if they are equidistant in height front to rear and side to side. If they are I'd simply make the cylinder deck square to the oil pan rails. I understand wanting to do this type of operation, but I firmly believe time and money is better spent elsewhere first. Stated another way, there is more value and power to be had spending one's money elsewhere.

As Josh says the baseline is from the oil pan. However the deck IS paralell to the oil pan rail so I dont think this would be a problem as it can be on V8s.
