Some engine bits...
,
Intake hoses were extended with solder and wrapped with detail wire to resemble the flexible portions of the hoses . Additional wiring and connector blocks were added around the fuse box for some visual interest.
Here's the engine in place, you can see the extended intake hoses, the bolt and hose clamp detail added to the throttle bodies, a power steering pump and hose,the battery got a decal and cables while the power brake booster may still get a vacuum line or two .
Good references are very helpful when you are trying to get the 'look' of the real engine. This is an old copy of Road & Track, I also use Google and E-bay motor adds for references.
