10 sec 6.1 ?

It can be done for sure i rekon...

Heads flow pretty well out of the box.
Say you need 530 hp to do a 10 with that weight.

Standard it makes what, 425 hp?

I rekon you can find another 100 hp easy with
after market air filter,computer to tune for optimum results,
an a bigger cam, an maybe a bigger throttle body!
I just realised now you said carb, argh..
Doesnt matter,i still think it can be done!
For sure.
Dont make me start finding you the parts lol.

Remember too,that this engine will weigh less than your
conventional 318,340,360....
