5k: Another Porvette: 1987 Porsche 928 with Chevy 4.8 Vortec V8

The last time we featured a Porsche 928 with LS1 V8 we put a little poll in the bottom of the feature asking our readers if they prefer stock to modified for the 928. By a margin of 6 to 4 the verdict was in favor of LS1 in all things.  Frankly I find myself conflicted as to the goodness of the GM powered Porsche…but given the options that the current seller of this car faced after his engine grenaded and rats ate his wiring, you have to sympathize with his decision.  Find this 1987 Porsche 928 with Chevy 4.8 Vortec V8 for sale in Stillwater, OK currently bidding for $3,050 with one day to go.

A water pump failure caused what the seller described as a catastrophic TBF, which we can only assume means total block failure, terribly burn fingers, Teutonic bill form, totally bad feelings, terminal belt fatigue. In 1987 the stock Porsche 5.0 liter DOHC Porsche V8 made 320 horsepower and this replacement engine should be good for about the same but with a small weight savings and reduction in CG height (the Porsche DOHC heads add a lot of mass to high up in the engine bay).

In the place of the thermally burned fuse Porsche motor is a Chevy Vortec 4.8 liter V8 (probably an LY4, LR2 or equivalent)  good for around 300 horsepower and 300 ft-lbs of torque. 

This car has some issues, it sat for a number of years after the seller had his engine transient burp failure and rodents ate wires, so some things don’t work, but he claims it runs/drives okay since it got the V8 transplant.  With any luck the reserve is reasonable and allows whoever picks it up to budget for some debugging and re-wiring of certain components.
