Comments: It's fast! Bonus: the gear ratio I selected lets me cruise highways at about 1800rpm at 72 MPH.

I'd researched this project on and off for about 6 months. Then this winter I was going to pull the 4 cylinder to have the engine bay painted. One thing led to another and the decision was made to go with a Rover aluminum V8. I found a good 4L engine in a salvage yard and broke it down in my shop at home. Mark at D&D Fabrications provided technical support and parts.

I started in late December of '08 and finished up in mid-June '09. The project took lots of weeknights plus every weekend for 6.5 months. I tried to focused specifically on the engine during the weeks, and on weekends I turned my attention to the overall car. I belong to the Fox Cities British Car Club, and club members share a great workshop facility. I couldn't and wouldn't have done this engine swap without the club's support. When the engine was ready, I took it to the club and then all my spare time was spent at the club shop.

Problems? The hydraulic throw out bearing gave me fits. Before I even started the engine, bad clutch hydraulic fittings caused a big leak. I had to pull the transmission to repair it. Later, the HTOB's hydraulic line chafed against the pressure plate, sprung a leak, and left me stranded 100 miles from home. (My bad for not properly securing it.)

The Advance Auto-Wire wiring set excellent quality but wiring is over my head. I wired the front and rear end of the car and engine compartment, but when everything got to the dash I ended up hiring a wiring specialist to complete it. He saved me a lot of headaches. My profession is graphics and this was my first venture into a serious mechanical project, but I always wanted to see if I could do something like this. It was worth it, but I wouldn't do it again.
