The twist being its a FWD application so dropping in a full f150 engine wont work this time.
The trans took a major dump so while the engine is out now's a good time to take on this project.
I'm trying to keep costs down so for rods I was hoping to use some "off the shelf" 351w pieces >>

then just get custom pistons to keep the compression ratio at about 8.8-9.1.
That rod isnt too long / too weak is it? Research has shown a longer rod+shorter piston helps reduce side loading on the crank. There may also be benefits of longer dwell time at TDC/BDC (maybe). I dont want the pin to intersect the oil ring though, that seems like its just a headache waiting to happen.
I dont have any crazy 350+ HP goals, i'd be happy with about 280HP and a mountain of torque. Those rods should be strong enough to support that dont you think?
What is the standard deck height by the way? and combustion chamber volume? I have some of the info already but i'm missing a few pieces needed to calculate the final CR.
96+ Windstar block (stronger/lighter than mine)
4.2 f150 crank (should make engine 3.81 x 3.74 bore x stroke)
standard deck height (??)
?? custom pistons
Its just in the planning stages right now, am I overlooking something major?
