Just for reference, I have a 72 Porsche 914 with a professionally built 300HP 327-V8 driving a stock 901 gearbox. Car is 'normal' with the exception of GT flares and will do Oh 2 60 in just shy of 5 seconds.

Also for the record, I'm going to modify the engine to include a steel 283 crank and double hump heads to increase the rev range as well as the horsepower.

Lastly, start searching for an H / 19:32 gear which you will need for 5th - move current 5th to 4th and current 4th to 3rd. Don't use 1st at all.

Good luck ... Ed

PS If you want to sell those double humps, let me know ... what state are you in - besides confused !!!
