help needed
 

I am building a GP RV-4 and I am at the point of installing the firewall. I have two questions with regards to the engine. I am installing a Saito 72.

1. Will the supplied engine mount be strong enough for the Saito?

2. I am not sure how I should mount it vertical, horizontal or inverted.

Either way I will have to make a lot of modifications to the cowl. The least modifications would be to mount the engine inverted but I am concerned with the engine being to close the the ground. Vertical might look great with the beautiful engine showing.

Has anyone built one of these with the engine? If so what did you do or what would you have done different.
