Which 4.3 Vortec do I have?

Which 4.3 Vortec do I have?

Postby Pengyou [OP] » February 7th 2016, 6:22am

I was trying to look up the specs on my 2001's engine. There is one version that has about 200 hp and another version that has 275+. Which one is in my van?

What is the eighth character of your VIN number? Most likely it's either "W" or "X".

IIRC, the W engine is rated at 190HP, the X at 180HP.

If the eighth digit of your vin is an E, you have the coveted 675HP LADA Vortec.
Otherwise, you have the same as advertised. If you were told otherwise, you may
be a candidate for re-education camp.

I was looking at what Chevy calls the ecotec - a V6 that puts out 285hp with 350 ft lbs of torque. It was designed to hook up to a 6 sp auto. I don't suppose that would be a simple swap? I am guessing the block is about the same size, if not identical.
