Blake:
The MGA 1500 had 72 bhp, the single carb Bs had only 8:1 compression and 65
bhp.
When I say they were Marina engines, it is because they were. Single timing
chain single carb generic engines with not one iota of sporting character.
Total piece of crap, IMHO.
Toss the pistons, cam, timing gears and chain, and single valve springs and
replace them with early parts and install twin carbs and early exhaust, and
it is true that you get back to the early spec. But why bother when you can
start with an early engine for a couple of hundred bucks and go from there?
I do not know offhand if there is a clearance problem with the all synch box
in the MGA as there is in early B's, but I suspect nothing that some
judicious 'tapping' with a suitably sized hammer wouldn't remedy.
