interchangable?

Not enough details need models engine sizes etc.

The 1999 is a 350 vortex 5.7L and I was told the 1995 was also a 350 vortex 5.7L but the intake is different and now I am worried I bought a motor that I am not even gonna be able to use. I was told they are different blocks but is that gonna matter? I have all the parts water pump, intake etc. from the 95 so if I use the parts for a 1995 will it still hook up right? I had a cracked block on my 1999 suburban and it could not be fixed. So I bought the 1995 thinking it was a 1999 the same as I pulled.

Whats the 1995 out of?

A Tahoe

I see a 1996-2000 long block tahoe engine and a 1996-1999 suburban long block engine working.How the 1995 one is different couldnt tell you.We dont have acess to interchangable software.I use www.rockauto.com to answer compatiabilty questions and thats what they say.Junk yards have that software though.I would never buy and engine without knowing it would work for sure.

I believe the 1995 engine is a throttle body injector engine which is different from the 99 engine which is a multi point injector. Also, the 95 is an OBD I engine and the 99 is an OBD II engine. I think adapting the 95 engine to the 99 truck would be very difficult.

That's right, it's a TBI engine, not a Vortec and nearly impossible to adapt, not to mention, against Federal law to do so.

Thanks for the added wisdom wrenchtech.
