From the flynfrog stable.
First up
A trx 250R engine. After market cylinder casting power valve off a snowmobile custom machining to fit the sleeve into the cases ends up with a 350CC engine 15:1 compression pushing 78hp considering stock was around 40 not a bad power gain. To make the rest of the engine take the power clutch is upgraded to an 8 plate. Second gear is custom heat treated, shift star shaved to make full power shifting easier.
Next up is a chevy lq4 6.0 L out of a van. Swapped the intake and cam adding a turbo should be pushing 550-600 hp on pump gas hoping for more out corn fuel garbage. Shoving into a BMW wagon
next in line is a 1963 430 MEL. Pretty innovative for its day. The heads are decked on and angle to allow for the combustion chamber to be built into the piston.

Last in line an L640 Dt rocket engine this was to propel my rocket over 20K ft. Scrubbed the flight this year due to electrical issues. But hope for better luck next year. Total rocket weight on pad is 9 pounds total at burnout is 2.5 you do the math.
