The Sunbeam Tiger engine installation was very tight, even with the small SBF 260/289 engines. Most of these cars have holes drilled via hole saws through the inner fenders to facilitate plug changes.
390 GT and 428 Mustangs had three exhaust bolts per port, due to the tight fit between the shock towers. Full size cars had just two bolts, one above and one below because there was enough room.
