I wasnt anywhere close to a clearance problem but it gave me an idea of where i was at.
I agree Pat he has to start somewhere cause it wont work the way it is now. I deferr any thoughts to you cause any advise you have ever given has been spot on.
If i ever want to build my 454 i am going to ask you for shure for some good advise
Stupid question but hard to tell from pics: is piston in backwards?
well after reading thru here and looking at the pics I have come up with the answer-----first it does look like the piston is out of the hole some and it could possibly be a 427 piston instead of a 454 piston--the putty is NOT marked from valve contact----I think he cranked down too far on his adjuster nuts and the retainer hit the guide/seal, never touching the piston
water ports for heads cooling are in back of the mark 4 block and open so your looking at the front of the block os that number one hole and is right ? from what i can see ???????????????????? mark 5/6 are open front and back but the mark 5 cnc bowtie is plug in front to make the water go thru the back of blockQuote:
