Hi Rate1 - Engine installation looks good - my - that is a big engine!!!!!

However, I don't see any triangular stock on the inside corners of the engine box - I also recommend drilling 3mm ish holes in the engine box sides into the firewall bulkhead so that you can glue in dowel pegs to strengthen the firewall connection to the sides....methinks that is a "stump-puller of an engine you have there !!

Cheers
