I know a fella who is restoring a MGA coupe but is planning to drop a Buick Grand National V6 into it. The thing should go like stink, but I can see the purists rolling their eyes already.
I'm rolling my eyes, but in part because using a 90 deg. engine almost ensures a barbaric chop job. The frame reinforcements that run from the 'goalpost' heater shelf area to the front shock area are important for structural rigidity on these cars, and there isn't room for a wide engine in there, so most oif the people that stick in V8s or 90 deg. V6s (the Buick is just a small block GM V8 with a couple of cylinders lopped off) just chop out these necessary frame pieces.
I was involved in an MGA with 215 Olds engine years ago and vowed never again. When I was in a position to swap a modern engine into an MGA chassis (on the Jamaican) I opted for the 60 deg. V6 which itself poses a few challenges (unlike the MGB chassis which has more space).
I kind of hate to see anyone chopping MGAs (why not destroy rubber bumper MGBs which no one will miss?) but if they have to it would be nice to see a 4 cylinder swap, simply because doing one means less violence to the structure of the car. There are some lovely Honda S2000 and various Jaopanese DOHC 4 cylinder swaps around. A GM LNF engine would produce more power than the Buick and take up less space.
