hey guys. bit of help.

i have a pair of 1.25 Su all ready to bolt on with manifold etc.

will they go ok on my engine?

i'm told 1.5's are best but will 1.25 work ok?

i also have some 1.75 twins in the house. but id need them rebuilt.

it is only a street car mind you.

as long they run ok give me a bit of kick im happy.

thanks for your help.

Twin 1.25s are fine on a 1275 if motor is near stock. If it's worked over with cam, big valves and ports etc, twin 1.5s are better, from 5000 rpm up.
