Keith Dordon has a SBC2 made into a V-6 for a LSR rear engine modified roadster on You Tube NA ove 600 HP... Great and shows how he did it all..
If you want a 200 cu in engine to make class, Dodge had a 198 cu in slant six. And, if you are contemplating a supercharged or turbocharged engine AMC had a 199 cu in six that was hell for strong. Barney Navarro built a 700HP version with 105 lbs boost in the mid sixties, twin turbocharged and burning alcohol, to run in the Indy 500. https://worldpowersystems.com/AMC/Navarro-turbo-motor/index.html But no doubt there are more modern engines available that will make more HP with less work.
Actually the SCTA class structure brakes at 120 - 183 CID. And at 183 - 260 cid. So a 200 inch engine would be kind of dumb. The 170 slant 6 has been run in the 183 class. People have run 7 cylinder 283 to make the 260 class. A 4 cylinder 350 can make the 183 class. And many have. Lots of parts around for a SBC. And they work well. When I wanted a 183 motor I used a 3 liter Nissan V6. Lots of them around and some are pretty racy. We had a couple records for a year or two. Then Kent Richies came out with his twin Hayabusa powered car and put us out of that record,
This is a 9 year old thread. By now Uncle Dave has sobered up and decided he can't do this. In fact he has not been seen on the HAMB in 3 1/2 years. But it is still fun.
Ha! look at article in Hot Rod Deluxe September 2019 starts at page 68: Half-Fast Skeeter (1/2 small block Chevy powered)
If this was still alive, there is always https://www.roadandtrack.com/car-culture/a23340313/motus-dead/ V4 LS engine
That engine was a Nissian 300Z or Maxima engine. SOHC two valve engine. But Jack used Honda V4s inline 4s, A five valve Yamaha. Hyabusas, A weird two crank sort of V4 Yamaha. Toyota car 2 liter engine. Lots of SBC engines. One a V7. Flathead. No brand loyalty there.
This has been some great reading! I remember reading about an engine that Ferdinand Porche experimented with in the early 1930's when he was working on an air cooled engine for his Volkswagen concept. It was a four cylinder two stroke that ran on two cylinders, with one pair supercharging the other two. It ran strong, but was also prone to overheating.
Ron Cohn - Bob Jucewic have 18 or more Bonneville and El Mirage Classic Gas and Fuel Altered and Classic Production records with their Monza. Some of which use 4-cylinders in a SBC V-8 block.
I know this post is 9 years old, but I have to respectfully disagree. Plugging that hole would shut off 3, 5, 2, &8. (middle 2/ left side, end 2/ right side) Every other cylinder in the firing order.
During the gas crunch of the 1970's the highly respected technical journal-Mother Earth News-did an article on running your V-8 on 4 cylinders! The guy I worked for at the time did two of them,a 440 powered ex-police car and a 455 Buick Electra 225.Both cars were so under-powered they were scary to drive. If I remember,you only had to pull the intake to make the modification [drilling and tapping the side of the lifter bore for a set screw to hold the lifter up?]Think you also removed push rods to those lifters. The 4 pistons and rods [2 middle ones on one side-end 2 on the other]just were along for the ride. He kept the Mopar for his wife to drive[poor woman] and the Buick got sold.The Mopar was pretty trouble free,but the Buick would break starter noses about every couple months.
Reading through this topic, I am surprised no one pointed out that the German and British V4 and V6 engine are quite different. Sort of look similar, but nothing interchanges.
