"In the mid-1980s, Hotrodders discovered the 215 could be stretched to as much as 305 cu in (5 l), using the Buick 300 crank, new cylinder sleeves, and an assortment of non-Buick parts.[5] It could also be fitted with high-compression head from the Morgan Plus 8. Using the 5 liter Rover (check out the references--)block and crankshaft, a maximum displacement of 317.8 cu in (5,208 cc) is theoretically possible."
anyone know where a Buick 300 is parked??:eek:
Oh my!:eek::eek::eek:

lots of these conversions done in the 80's.this was to keep the ADR27 engine number.its common to come across leyland blocks with rover heads and engine numbers stamed on.
the give away is the leyland number flange brocken off or modified.
I have been asking myself WHY?
Why would you go to all the machining to modify cranks that are unattainable in OZ anyway and are 50 years old rather than buy a tailored stroker kit that is made for the engine.
Unless you have your own fully equipped machine shop, the end cost would be similar IMHO.

Can you give such examples of said kits?Quote:

(5) I am a Machinist, First Class, and can do any mods needed to the crank other than finish grinding.
A Buick 340 is no heavier than an RR with a steel bull bar and/or winch which I won't be fitting.
