Welcome to Lee's Performance

Both of them have built a LOT of big bore busas over the years

We have seen real numbers such as: 160-164 SAE stock piped and tuned and 180-185 SAE with just JE 1397 pistons added. About 20HP would be relaistic. To get any more with just big-bore pistons would be sligthly inflated. Obviously with a head and cam package you would see more.
