These can be fitted to the 1.7 340 as a free flowing exhaust manifold. Will fit with a carb or injection inlet.
Great way to solve the downpipe flange cracking problem.
Can be used with 340 1.7 8 valve engine or in a 400 series series engine swap B18/B20
You will need part of a 440 down pipe to connect to your exhaust system
