What kind of 351 Windsor Do I Have

[Ron61]

I am not sure how much this will help but the D1AE-6015-DA 10 breaks down like this from the book that I have. It was a 1971 as you said, the A means it originally came in a Galaxie, and the E = Engine engineering. The 6015 is for the base engine and the rest indicates if a part has been changed. But there are so many variations on this that I am not sure just what all of it means. As for all the measurements, you will have to wait for one of the engine guys to really answer your question.

351w main brg tunnel bore is 3.193" so 1/2 is 1.596". Now if you recheck your deck to tunnel dimension you will find that is around 7 7/8" ( 7.875" ) and if you add 7.875" + 1.596" = 9.471" [ pretty close to the Windsor 9.480"]

Now you say your crank is 4.170" stroke;therefore 1/2 stroke is --2.085" + 6.125"rod + 1.280" pin height to give a total of 9.490" which if your block when measured accurately checks out will give you a 0.010" out the top of the block piston protrusion. If you find this is the case you should look for a later block whick has a deck height of around 9.510" or if possible [ might not be practical ] machine the piston crown to give the correct piston to head clearance- dont forget to recheck valve pocket depths/clearance.

Thanks for some quick responses guys. I talked with the kit supplier and they've sold thousands of these with no complaints about fitment. When I start turning the crank to bring the piston up the bore, I have about 5/8" clearance between the nut on the con rod and the skirt. The I-Beam rod has about 1/2" clearance.When I took a rough measurement to try to get deck to main centerline, I left a bearing half in place, so we're not using the actual bearing bore through the block and caps. Nominal main bearing size on the crank is 3.000", so the I.D. of the block sleeves should be about 3.001". Half of this added to 8.125" gives approximately 9.625". I'll take another look at this making sure the ruler is parallel with the cylinder bore and use the actual block main bore size. On my lunch hour, I dropped the old crank in place, but I couldn't get a piston back in. I wanted to see where the "rebuilt" piston was with respect to the deck.
