1958 PORSCHE 356A 1600 SUPER CABRIOLET
NON ORIGINAL ENGINE (# P605848) 1,582cc (1.6L) Type 616/1 pushrod flat four engine built around 1956 for a Porsche 356
This VIN # 150527 belongs to a 1958 Porsche 356 A (Type T2) Cabriolet.
The 150001–151531 serial sequence was designated specifically for Cabriolet bodies built by Reutter during the 1958 model year.
The engine # P-605848, as established, this is a 1955 Porsche 356 A (T1) 1600 Normal engine block. It was manufactured in the late autumn of 1955.
The "P" prefix designates a genuine Porsche passenger car engine, and the 60001–60608 serial sequence indicates it was one of the very first batch of 1,582cc engines produced late in 1955 for the debut of the 356 A model year.
Engine Specifications:
Internal Porsche Type: 616/1
Configuration: Air-cooled flat-4 boxer (Pushrod OHV)
Displacement: 1582 cc (1.6 Liters)
Bore x Stroke: 82.5 mm x 74 mm
Power Output: 60 bhp (DIN) @ 4500 RPM
Crankshaft Type: Plain-bearing (Standard "Normal" spec, as opposed to the roller-bearing Supers)
Because this number falls exceptionally high in the 1955 range (ending at 60608), your engine case was cast and assembled in late autumn of 1955. This was right at the major transition point when Porsche replaced the old 1500cc pre-A engines with the new 1600cc variant to power the incoming 356 A. Given its high sequence number in that short opening window, it was originally mated to a very early 1955/1956 Porsche 356 A Coupe or Cabriolet.
Transmission:
The details provided match the precise stampings found on a vintage Porsche 356 Type 716 manual transmission case. In the Porsche 356 community, these markings are used to decode the exact factory configuration, build timeframe, and unique serial identity of your specific transmission unit.
The elements on your gearbox case decode as follows:
TRANS / 716: Type 716 transmission, which was the fully synchronized 4-speed dual-mount gearbox introduced by Porsche late in the 356 A production run (specifically around late 1958/1959) and carried into early 356 B models.
58: This represents the factory date stamp. Stamped inside a small circle on the casing, these numbers indicate the week and year the transmission case housing was cast. A "58" marker signifies it was manufactured in 1958.
BBBC: This is the factory gear ratio code. Porsche used specific letter combinations stamped next to the transmission type to identify the internal gear cluster layout. BBBC means your transmission was built with standard factory ratios: B for 1st gear, B for 2nd gear, B for 3rd gear, and C for 4th gear.
20105 (or similar 5-digit number): This is the unique transmission serial number. Stamped directly on the front or bottom casting flange of the housing, this number can be used alongside a factory Kardex or Certificate of Authenticity to verify if the transmission is "matching numbers" to a specific 1958 or 1959 chassis
