Riley - Riley One-Point-Five.
The Riley One-Point-Five became available toward the end of 1957, some 7 months after the similar looking Wolseley 1500, as part of the BMC range. The Riley One-Point-Five was based on the Morris Minor chassis using its suspension, rack and pinion and floor pan, but using the larger 1489cc BMC B series engine. This engine was then mated to a gearbox from the MG Magnette. The Riley One-Point-Five had the more powerful version of the 1500cc BMC engine fitted with twin SU carburettors producing 65bhp as standard. Consequently, as a result of the better performance the One-Point-Five was fitted with much larger Girling brakes. The capacity of the Riley One-Point-Five never changed but for 1962 the engine did get some upgrades with a more robust crankshaft having larger journal sizes, and it was these Riley One-Point-Five that were often raced and Rallied in period. Although virtually identical to the Wolseley 1500, the Riley sold in less numbers because of its higher price tag. Production carried on to 1965.
Riley One-Point-Five tyre size was 5.00x14 originally, and the radial tyre equivalent to this is the 145R14 tyre. Blockley produce the perfect steel belt construction good speed rated example, with period correct tread pattern and correct diameter 145R14 - see full details below of why the Blockley 145R14 is the best option for the Riley One-Point-Five at the link below:
