I thought I would start a thread here and introduce myself rather than go straight into the tech section. First, a little about myslef,My name is Corey, I'm 36 years old and I live in Dayton Ohio. I am an engineer/fabricator/CAD designer at the local Air Force Base. My first car was a 67 Chevelle I bought when I was 15 (still have it) and just thought that it didn't get any better than a Chevy. Then, when I was 19, I rode in my cousin's new to him 1993 Cobra, and evertything changed. Later that year I bought a 93 Mustang GT convertible and started modding. I finally got rid of the car 3 years ago and by that time it ran a best of [email protected] on a 275/50 drag radial and was still banging gears manually.

Now, the reason I am here. After selling my mustang, I got into performance boating. I have always been a boater, but just always used my Dad's old Baja. Well, two years ago, I bought my own boat, a 1998 Checkmate 253 Convinsor. As many of you that have ever been into boating or been around it, it is HUGELY dominated by bib block chevy power. My boat is no exception sporting a GenVI 454. Well, of course, the modding bug bit me almost instantly, and I wanted my boat to go faster, so I started looking into building a new motor and began collecting a few parts. Well, needless to say, I am already fed up with this Chevy crap!! So the boat is getting a BBF!!! I have always loved Ford power, having run and built small block Fords for years and years in my Mustang. Plus, most of the people I boat with are big time Chevy guys, so it would make my day to blow by them on the water in a blue oval powered boat. With my backgroung being in small blocks, I have a few questions on basically where to start. What kind of block should I be looking for to take the constant beating and load that a marine application puts on a motor? Should I be looking for a 4-bolt main block or would a 2-bolt main block with a girdle work? Are there any other 4-bolt blocks out there other than an A460? As far as HP numbers are concerned, I am looking to be in the low to mid 600hp range. I have a M1-SC Procharger with water to air cooler that I will be running in a blow-thru carb set up, so the motor won't be too radical. No crazy compression, most likely iron headed, things like that. I won't be spinning it to any crazy RPM's either. Most likely in the 5000-5500 range. I really want to build something that is low maintenance and really reliable. I have come across some of the stuff that I will need in order to make the motor work with all of my Mercruiser stuff, and it actually doesn't look like it will be too bad. Some minor fab work, motor mounts and what not, but that's no biggie. Like I said, where I really need the help is where to get started on the engine itsself. Block, heads to look for things of that nature. My goal is to be "That Ford powered boat that will surprise ya on Lake Cumberland". Any help is greatly appreciated!!!!
