Can a 2014 4.3 intake manifold and heads fit 2002 4.3 block

Just as it says, can a 2014 Silverado 4.3 intake manifold and heads work on a 2002 S10 blazer block? If so would it make a drastic change to be worth it? Thanks Rex

Pretty much a completely redesigned 4.3L, so as cool as it would be, the answer is no...

You're comparing our iron block and headed 4.3L's that are based off the Gen II 5.7L (350) to the newer aluminum block and headed 4.3L that are based off the Gen V 5.3L. Although each generation 4.3L shares the same method of basically hacking off 2 cylinders from the V8 in their family, they two generations are vastly different from one another.

However I'm sure with the right wizardry a complete engine swap wouldn't be out of the question ;) but at that point you might as well start looking at adding those missing 2 cylinders...
