Quote: Ahhhh, the voice of sanity is clearly heard.
Good on you. I have often said that buying a service manual for the car, &/or the engine you are playing with is the best automotive investment you can make.
It should also be the first investment you make after the vehicle itself. Great wisdom, & a lot of how to's & tech specs are contained within, & all for cheap.

The second engine is always a good idea. Once it's built, it's a simple matter to slip it in, & the stocker is always there as a backup should something unforseen occur.

Good advice Stevo.
