Chevy & GMC Vans

I have a 95 safari that has cpi injection on it and a 98 astro that has mpi injection.... the 98's engine is toast but the injection system is good.... can i slap the 95's block and heads into the 98's body and bolt up the mpi injection setup rather then the shitty cpi??

Thanks

Don't quote me on this but I think the 96+ vortec injection is a different head and bolt pattern. Basically the intake plenum will not bolt to the older heads. This is only what I think and not any where near 100% confident.

See i was pretty sure of that same thing... can't remember but i think the pre-vortecs are 23° and the vortecs are 19° or 21°.

I'm still researching this as the 95' was/is an odd ball year in these vans.

I know for sure that there is a difference on the V8 motors concerning the intake bolt pattern, between Vortec and non Vortec. So if this is true for the V6`s, then you will have to swap the heads and intake onto your `95 block.

Learned something today... in the V6's anyway... there is 2 generations of the "vortec" line.

They seem to classify the 87-94 as gen 1 and 95-05? (whenever they quit making them) as gen 2.

Worst case scenario i have to swap over the heads anyhow... which is ok because it's likely a good idea to check / replace the timing chain anyhow as it has 260,000kms on it.

Gordon,

Just kind of thinking out loud and might learn something too.I am not sure if the exhaust manifolds are the same here(because of the head angles changed,would think the exhaust ports changed and different manifolds where used) and I would guess if the injectors are not the same system,a computer swap would be needed as well.

starting to sound like it would be easier to swap in a v8....
