I thinks if you calling it a 4.3 it going to be a V-6,I bet they are the same as a 5.0L or a 305

I hate to disagree with you, but a 4.3 is a V-6 engine. In 1995 GM never made a 4.3 V-8. Is this engine a newer engine? Is it a 327 out of a newer silverado? I believe if you convert your cubic inches to liters, you may be surprised to find a 199 does not compute to a 4.3 liter. Sorry! 4.3 computes to a 265 cubic inch engine. If you will look on the front of the engine block (facing the windshield) on your left, on a pad just below the cylinder head you will find a code stamped on a pad. There will be some numbers that don't mean a lot, but there will be an engine code that will be something like AG or TMG, but a sequence of letters that identify the engine. Take those numbers, and call a Chevrolet dealer, ask for the parts department, and they can give you the low down on the size of those rod journals from those letters. The numbers only tell you the date, factory, and who put it together. I hope i have been of some help to you. Good Luck!

Chevy made 4 that's right 4 engines, that were 4.3L. The latest of these being the 4.3L V6 that every 'expert' knows of and the LT based L99 4.3L V8, having a 3.736" bore X 3.000" stroke. It has a desirable 5.940" rod. I will get back 2 U with the part number and journal size as I hope to use a set in a 383 for a 1.584 rod to stroke ratio,savvy?

Not the greatest engine GM ever made, but a good place to start would be GM themselfs 1-800-222-1020 GM customer asst. they could point you in the right direction.

The rods journals are 2.100" They used the same 350 crank as the lt1 350's, with a tiny bore(i think 3.5" bore)
