Aluminum slant build

Ultimately its YOUR engine. Im just trying to save you some heartburn and disappointment. Even Doug told you over 9 to 1 on an Aluminum block is bad. This doesnt even take into account the fact that Doug has seen hundreds of these and put at least 15 of them together as warmed up street engines. Most of these ended up torn down for various problems.
Also to consider is the amount of work and dollars you will have to put in just to see if it will work.
Dont forget about the corrosion problems with this engine as well.
Im not trying to get you to not build this just dont over do it. There are a lot of ways to make a slant not be a slug and a 9 to 1 engine can be fun to drive.
