Your MGB Coupe has what engine now?
They came out with optioned Rover V8 engine.
Why not fitted a stroker Rover engine, alloy block, 400 hp easy.
Would be way fast as a street car.
If you have your heart set on a SBC, I would go for an alloy block and heads.
Otherwise the Rover V8 is the best option.
Hope it works out for you.
