• BRG with a nice interior and an engine that's only partly anemic, lovely. Great buy for the price. The v6 likely weighs about the same as the old 4 so any extra power, revs, or torque are very welcome. The lack of power steering and a brake servo means the drive is very connected. Suspension geometry leaves something to be desired with the stick axle out back, but they're plenty nimble. The coolest feature by far is that it's one of the few small cars that has room for big people. I'm 6'2" and 300 pounds, and I'm quite cozy in mine.

    Just make sure the SU fuel pump was replaced with a Carter or Holley, or literally any other brand of fuel pump. Hell, even a Lucas pump would be more reliable than the SU unit. I've known multiple MG owners to carry a spare, or even wire a backup fuel pump to a switch for when the primary pump failed.

    • SlowBoy,
      Well said. I've always been a fan of the MGB but never had the opportunity to own one. Somehow an engine swap in one of these seems like less of a sin than doing it to an Alfa Spider…dunno why.

    • Numbers aren't fun. Sensations are fun. Unless you're racing, a 50% increase in horsepower isn't worth getting rid of the high rpm music from an Alfa engine. Being lazily ferried along by a gob of torque from a pushrod v8 is nice, but having to thrash an italian 4 to redline just to keep up makes for a much more exciting drive. That sort of goes out the window if you build your v8 with a hot cam and high RPM capability, though.

      That's why my MG has a mildly ported Mazda 12a in it. It sucks to drive at low RPM. Bury the pedal at low RPM and the fat twin barrel side draft Mikuni gives up all intake velocity, giving you the disappointing gargle of a bogged engine. Crack the throttle above 3k RPM and you actually go somewhere. Above 5, and you get the sonorous blast reminiscent of a big 2 stroke. Above 7 and the scenery disappears with frightening immediacy in the mirrors. Above 9 and you better upshift and repeat, because you don't want to be around when the cops show up.

      MGs are great starters into classic cars, though. They're accessible, tossable and just maintenance intensive enough to teach you how to casually turn a wrench without breaking the bank. (Porsche and Lotus, I'm looking at you) The stock engine didn't have many merits when it was new, so swaps have been popular for a long time, and seem to command lower prices than unrestored originals.

  • I happen to own a 72 B-GT with this set-up. Manual steering & brakes. It's got a nice burble at idle. I'm running the SU fuel pump with a Carter backup. Keeps up with traffic very well, but it's still a little gutless off the line. I'm running a 3:07 MGC ring & pinion. At 100km/h (62 mph), it's turning 1900 rpm. The 347 stroker I'm building for it will fix that. 🙂 Happy Motoring
