Wow. I never did any Drag Boat Racing. I ran APBA 5 lap competition.Glad to see other crazy boating people.
This is my baby. It runs upper 120's in a quarter @ 8.5 seconds.

DAMN!!!!I never officially competed with boats but had a lot of races with this. I grew up with boats and owned many over the years. Boats, cars, and motorcycle my weakness.

The Circle boat and Dragboat are somewhat different animals. I agree, the Biesmeyer is still probably the top Circle boat out there. I was never comfortable with the Circle boat racing, there is just too much water movement for me. They are fun to watch, but they take more balls than I have. Dragboats run on smooth water and if anything starts to feel unnatural, I can back out. I came from street racing and liked boats so it was a natural progression. It's much quicker than any car that had. My hull is a Cole TR-4 runner bottom which I feel is probably one of the most desirable hulls for a dragboat. I'm running a 540 BBC with a 14-71 blower using e85. I say it's a BBC, but there is not a single GM part in the motor. Like you, I'm geared to turn 7,500rpm. I play with it now mostly on the local river or lakes. It's pretty healthy for a lake boat, but I was involved with some pretty serious racers. One of them is a Pro driver and drives a Top Fuel boat that runs in the 260's in only 800 feet. Most of the other racing classes now run 1,000 feet though. The fuel boats are fun to watch, but way out of my interest level of driving or maintaining. I started playing with these V-Drives in 1970.Wow. I never did any Drag Boat Racing. I ran APBA 5 lap competition.
I ran three different classes with the same hull, (I went through three hulls in my career,)
In the picture, I was as running Ski Racing Runnabout. Limited to 399 cubic inches, carburetors, and legal racing gas. Aside from that, you could do what ever you could afford.
The way we built a 399 Big Block was to take a 427, bore it .060 over, send the crank shaft to Lunati to have it welded and destroaked to around 3 7/16 inches. I used 1/4 inch long Carrillo Rods. The roller Cams usually were around .284 degrees at .050 lift, and .780 oft. We revved that destroaked Rat Motor to 7800+ on the straight always. Compression was around 13.5 to 1 on the Air Flow Research Heads.
I ran the same 11 1/2 x 15 Stellings Prop in all three classes. I just changed the gears as power went up. In Super Stock, where we ran what as basically a bone stock L-88 Chevy, I ran around 10 % overdrive in the Cassel V Drive, in Ski Racing Runnabout, 15%, and in K boat, which as just about unlimited, I ran 23% overdrive. I ran a Crower fuel injected 496 on straight methanol in K Boat.
the Hull was a Biesmeyer, arguably the finest Circle Hull ever build.
I am a little embarrassed I can’t figure out which Hull you have. I would guess a Sanger, but probably not.
While I did not race 1/4 mile drags, I knew everybody that did. Back in the ‘70’s, the popular hulls were all runner bottoms, Hondo, Brendella, Cole, and Sanger being the most popular.
People would ask just how dangerous this was. I personally saw four friends die during my 10 year tenure. As crazy as I was, I feel fortunate to come out in one piece.
Tell me all about yours. It’s been a long time ago in a Galaxy far away when I did that. I don’t mind saying, I was pretty good at it.
I pissed away so much money on race cars, it isn‘t funny. Started with drag cars, 70 SS454 Chevelle, then a 68 Bigblock Corvette. This was before nitrus or supercharging was the thing. Naturally aspirated on race gas. This progressed to road racing in the SCCA GT-1 class with tube framed C4 Corvettes. The engines were from Pro-Motor Engineering in Chicago, small blocks with dry sumps, roller cams , and custom carbs. The chassis were five link rears with coil overs on all four corners and a 40 gal. fuel cell.
A set of tires lasted a weekend and u consumed a 55 gal. drum of racing gas as well.
We had fun traveling around the country and even made the Run-Offs at Road Atlanta.
In retrospect, if I had to do it over, I would have taken my money and purchased an old, antique airplane and restored it. At least when I was finished, I would have something of value to show for all my efforts.
Racing is always chasing technology, which means if u are not constantly spending money to keep pace, ur car becomes outdated quickly. That outdated car is worth Pennie’s on the dollar should u decide to sell it.
just some thoughts from an old racer.

I remember the Cole runner bottoms well. They came out in the mid ‘70’s, along with the Brendella. Before that, Hondo pretty much was the go to hull for drag boats. They tried to produce a good Cicle hull. They were a fast hull, but didn’t turn worth a darn, or at least, not like a Biesmyer.
