2.8 to 3.4 dohc swap -

[Dave]

okay, I have the opertuinty to get a 1991 Z34 3.4 DOHC engine, transmission (4T60-E) Full wiring harness, and even the engine cradle but if it does I'll just swap the two cradels with everything on 'em, so I guess I am wondering if I would be able do this with my 88 Buick Regal, I don't know if the Cradle will swap, but that'd be my goal, just to move everything at once like that, and with the Regal cradle out of the car I'd do the wiring swap.

Some problems I think I may encounter would be the full digital dash in my Regal (tach, speedo, oil pressure, volts, tempature) but I think I can work 'round that for now, so any suggestions would be wonderful, I'm just doing some research before I buy anything -

Thanks in advance,
--Dave

.. anyone do this? will the cradle's swap at all?

You will have to swap the cradle, and it does swap in. The digital dash will be an issue for sure because the dash reads the ALDL data...which is different for the DOHC engine. Im not sure how you would make it work either other than swapping to an analog dash.

I can go with an analog dash - perhaps I shal go with this
