Not at all,because the 4 into 1, the 1 has a larger bore for greater exhaust flow.(look at any race car they are all 4 into 1.....)

Is a 1998 gmc sierra motor the same as a 1999 blazer motor they are both v6 4.3l

yes the difference is in the exhaust manifold, the difference in clearance between the frame rails, order new exhaust manifolds (aka headers) and retain the motor mounts from the engine being replaced.

The other day I tried to crank my 1984 camaro z28 it turns over but wont start. I recently put new headers and exhaust on and accidently broke a small sensor on the passenger side of the engine block below...

It could be that you keep cranking it and flooding the block.This was your crankshaft sensor replace the sensor very cheap bring it with you to the parts store and they will give you a new one then your set to go.

if the exhaust is just cracked i wouldnt worrie about the engine because you still have a lot of backpressure and it should not burn a valve. but replacing the header is a good idea if the header itself is cracked. and to tell you the truth your mechanic should be responsible for the cost of the repair since he broke it in the first place. In the shop i own if one of my mechanics breaks something it comes out of my pocket to replace. its all part of the job sometimes things just happen and you have to take the responsibility for it
