looking at the .32 dynamite engine specs 1.18hp , the os is 1.35 + its a smaller engine and weighs less i believe -

The blocks are two different sizes by a bunch. The parts will not interchange.
Let me guess, you're looking for a replacement for the Shockwave 36. Try the OS .32, it should go in a lot easier.

hi was looking at the o.s .32 it says 1.1 hp @17000 rpm my dynamite 32 is 1.8 hp at 28000 rpm so is the o.s one faster with lower rpm new to this stuff the o.s engine has a practical rpm range of 2,500-21,000 though.

Yeah, and the SW 36 does 35 MPH out of the box. A lot of manufacturers today are playing games with the numbers like they are used car salesmen. You'll find that OS is using more real world numbers than most of the others, this had already been proven on dynos. The other problem with getting a replacement engine in this size is difficult as these are the only .32's that I know of. The 4-wheeled engines are starting to get up in this area with the .30's now but they don't do you any good. The only other way for you to go is up, maybe a mild .45 . It would take some work but they could be another choice.
