I have a beat 1978 Olds 98 with a factory Olds 350 engine that is basically trash. I have a second Pontiac 400 engine from a 68 Bonneville(only one set of motor mount holes in eash side of block). Without going too deep into my pockets financially, I would like to install the motor into the Olds. The only problem that I think that I will have is the motor mounts. Which year model mounts and for what type of car? Any other problems that I may be overlooking? Once the car is toast(3/4 of the way there already) I will take the engine/transmission out and donate the car. Time isn't the problem, but would like to keep the project under $200 if possible.

I doubt if you will find any factory mounts that will make this a 'bolt in' swap. You will probably have to fabricate something up to make the swap.

most resto/preformance vendors sell an install kit for the early blocks to the late chassis.

they aren't much money and work well.

I'll try to locate something if its available. Thanks for the input.
