Has anybody done this to a vh45de? I saw a post by defrag010 but it looks like he edited out his portion of the thread.
This is what I'm thinking, making the assumption that the block deck height is 8.675", stroke 3.255", combustion chamber volume 54cc, and a .030" head gasket.
manley modular ford 4.6 stroker pistons 3.7" bore, 1.2" pin height -23cc dish (they come in several dish volumes) 595470c-8
modular ford 4.6 stroker rods 5.85" length be bore 2-2.125", be width .940", wrist pin .866"
I'd have to narrow the rods down to .865" from .940" turn down the crank rod journals to either 2.125"or 2" ( the 2 sizes I found for this length rod) and bore the block to 3.7". By the way how much can the block be bored before going through the liner? Is .065" too much?
With this setup the engine will have an 8:1 cr and a 1.8:1 rod ratio but the piston is out of the hole by .002". I don't know about the availability of after market head gaskets, but with rovers you can get gaskets from .020" up to .050". I don't see being out of the hole by .002" if thicker gaskets are available. If they aren't I could reduce the stroke by .004" to put the piston at zero deck clearance.
The pistons run from about $630 and up, the rods from $250 and up, Although the rods I found for $250 seemed questionable. Has any one heard of SGI rods? Me neither. Found them on ebay and unless some one has something good to say about them I' gonna pass.
Excluding the con rod machining and possible piston notching, which could be considerable, parts would put this at give or take $1k for forged pistons, forged rods and a pretty solid rotating assembly, which is considerably cheaper than a set of CP pistons @ $1.4k a set.
So am I dreaming or is this a realistic possibility? My goals here is a 600+ hp TT build. Rip away
PS I just noticed that the wrist pin on the pistons are chevy sized, .927" so rods are much more plentiful and cheaper too
if the piston is out of the hole .002 then thats not going to be a problem as long as the valve pockets are cut deep enough for the cam your putting in, thats very close to zero deck. ive personaly never hurd of SGI rods. what kind of material are they made of and what design? with my build i can tell you im gettin rods made up from K1 technologies and pistons from CP NOT cheap lol but thats the price you pay for insurance. anything is possible when building a custom engine, good luck man
