I have a 1985 Corvette that needs a new motor. Instead of shelling out cash for another GM engine, does anyone know if it would be possible to swap in a V8 from the Porsche 928 series? If so, which engine would be the best from that model line? Thanks for any help.

That sounds like a fun idea. Until you start counint the $$$. There are smooth, high-pref 928 engines, but the cost is high and the options are small compared to any Chevy engine.
Trust me. I'm finishing up an engine re-build on my 928 and it's going to be $2500 with no mods whatsoever. "Like new" but nothing special...outside of being a sweet 300hp!

300hp, must be a little later than mine, I only get 240 or so in my 84 :(
I'd stick with GM - you can get a lot more bang for your buck from a crate motor, and the maintenance won't be nearly as much as a 928. For the kind of money such a swap would take, all in, you could likely get a 32-valve 928 engine with a nice car still around it. There are S2s on Autotrader for 5 or 6 grand. Emanuel
Makes no sense dollarwise. It would be easier to buy the whole 928 and get the front engine / rear transaxle advantages outright.
The wiring harness on the 928 would cost you more than the whole Corvette replacement.
Actually the torque numbers are similar, the horsepower numbers are not. The
5.0 liter 928S was 288HP/318lb/ft of torque while the 5.7 liter Corvette had 230HP/330lb/ft of torque.But..I agree...probably a troll.
