4.3 vs 3.4

[WA-Wheeler]

There are multiple versions Alan. TBI, CPI,SCPI, Turbo'd , Carbed, and even a boat version :haha:

Later model SCPI are the best of the bunch and most sophisticated of the bunch. The Turbo version's are pretty rare (typhoon/cyclone) and run a totally different intake/injection setup compared to any other versions..

But realistically there are only 2 motors--with and without balance shafts.

BTW, LOL, ASAP, SOS....??

One thing i know, is that the 4.3 is everywhere. Parts are soo easy to get, including a mass junkyard stock.

Hi All:

So what does SCPI mean?

Crash, could you explain how the with and without balance shaft versions of the 4.3L engine are different?

Thanks!

Alan
