What is different from the x18 than a18.Also the 383 with the bravo will be slower than a blackhawk with the same hp.surface drive compared to a bravo none.

A friend had a 500 TRS 22c that ran low 80s gps so the 18 should be good to go I ran an 18 454 400hp volvo at 75 on the nordscog so it was probably 73 really nothing fancy but the hill prop, external steering and hydro nosecone.

Wow, what boat is that?

-----The year...1979. I lucked into a brand new leftover X18 powered with the 330/454 TRS package. The boat would do 70 absolutely stock down to the prop. I found out talking to John Chisholm (DONZIs owner at the time) that they only built a few big-block 18s as they felt there might be a liability issue. Drive was very deep and the boat would heal way over in a sharp turn at slow speeds. Enough that the boat would take on water into the cockpit. Wife wasnt exactly thrilled by the boat so I traded even up for a brand new 1980 Corvette.......Bill S
