Why wouldn't a 1' longer hull (more stability), weighing the same or less than my 232, be able to match those numbers especially with an additional 30hp?

I'm really not familiar with the term "pad" .... what does it mean?

Got ya ..... and Thanks!
No, my 232 does not have a pad.
It's a rounded V all the way to the rear of the boat.

Pad sizes can also vary from a few inches wide to very wide like Velocity.

Around here in freshwater at 600-700 feet elevation 70 mph STOCK 502 powered baja outlaws are NON-EXISTENT. My 2000 272 ran 62-63 with a normal load stock with 502 mpi,have met people with 272's with 330hp/310 hp 454's that claimed to run 60-62 but only ran 56-57 when clocked using a gps. Running my boat stock, propped perfect,on fumes with nothing else in it I saw 64 mph from what I remember BUT I never had a labbed prop back then either.Your speed with base motor is very similar to the 272's I'm referencing with same motors,you will see 62-63 mph pretty easy but it will probably take more than 85 hp and a labbed prop to get you to 70 mph. I'm sure 1/2 dozen guys will chime in about their 70 or 75 mph stock bajas 
but don't believe all the BS unless you see it on gps. It took a blower,merlin heads and other upgrades to get my boat to mid 70's (around 650 hp),headers,msd,several ecm tunes,several labbed props,more boost and countless testing to get upper 70's loaded and low 80's light. Salt water and sea level with a labbed prop might get you mid 60's,running empty might get you 66-67 mph,just don't get sucked into all the bs and hype from some of these guys who cannot prove their 70 plus mph claims,Smitty

Hey Smitty
Why does anyone have to prove their claims?
No one is on trial .... nor are we trying to sell anything.
We're simply sharing information we each believe is true.
If the information seems suspect ..... your free to ignore it!

Some people do not realize how much you have to do just to squeak out an extra 1 or 2 MPH. OH Yeah, to answer your question I think you are probably looking at about a 62/63 MPH.
Did someone say something which you think is wrong?
