By running the vins and serial numbers on the VORTEC engine its self and going to the DMV you might have to pay them $50 but it will give you basically all the information on it! (:
I have a 1996 305, Vortec with that number on it.
135 from front to back located on the drivers side or right.246 front to back located passenger or left.
The vortec has bigger pistons
Look at the intake manifold. A vortec engine has 8ea. All the others have 12ea.
The 2001 model of the Light-Duty Silverado 1500, had an option of four engine sizes; a 6.0L Vortec V8 engine, a 4.3L Vortec V6, a 4.8L Vortec V8 or a 5.3L Vortec V8. The Heavy-Duty 1500HD comes with three engine options, these are 6.0L Vortec V8, 8.1L Vortec V8 and a 6.6L Duramax V8
The 4.3 Vortec engine never had a carburetor.
" vortec " is a title that GM uses on some of their engines
A vortec 5.7 is a lt1 based engine.
will a 4.3l vortec starter fit a 305 vortec?
No it is not even close.
Yes as long they were mounted on the same side of the engine.
