broken cluncking 33

[alfa331.7]

gday guys

sooo.. last night decided to take my 33 for a spin and I got a bit excited and decided to see what they can do when maxing out each gears usually 33 1.7 twin carbs will hit 80km in second yeah? well mine did 95 then bang ban bang clunk
so drove it back to the garage running on I think 2 cyclinders and haven't touched it since
I think I have blown my bottom end so whats the cost of rebuilding a bottom end these days?

First figure out what you've broken, then you will probably get some responses.
