The short blocks remained unchanged from '05-'10 but the heads were changed in late '08 to accommodate one-piece 12mm plugs, and for '10 the intake manifold was modified with the CMCVs as part of the unit instead of bolted on with separate plates.
My '07 was a May build and it had the updated thermostat.the cooling system is different, that's probably why your searches are 05-06 specific, then later years. in 07, Ford changed the thermostat location from drivers side mid coolant hose to pass side coolant crossover, a much simpler and effective location. when, in 07 it was changed I'm not sure. the later coolant crossovers are hard to find for some reason (looking for 1 myself). the Ford part # for the crossover is 7R3E-8C369. good luck

The stock crank is stout enough to handle up to 700hp so you can keep it. Also don't forget these:
TSS- 3v Billet Oil Pump Gears - Justin's Performance Center
well yeah obviously... i just wasnt aware that the 3v's where known to have a high failure rate. Thanks for the info!That depends on whether you'd prefer to invest $400 on billet oil pump gears, or risk a catastrophic failure of the stock powdered metal gears and be left with another blown engine.
The stock powdered metal oil pump gears are reliable on N/A builds but not when you add forced induction, especially when it's a supercharger as it places a higher load on the front of the crank which drives the oil pump.well yeah obviously... i just wasnt aware that the 3v's where known to have a high failure rate. Thanks for the info!
