@@MetalWorldPeace4675 Josh archs first wins ever for cycle drag where with my engine. won every class pro / pro extreme / pro outlaw with my build. Also .. lots of others out there on bigger levels floridas fastest small block jesus delgado did 108 mph and had crown on my engine . Texas same / cally same .. all top winners I never ask them to speak out or go to the races to promote myself. I just build and sell. I’m doing ok. Maybe not the best but def a top contender. It’s a rolling field. Research for a year then put out the baddest stuff like the biggest small block gx200 on the planet 300cc only one doing that. It’s a year of research / then a year of being sold as the best. Then someone else does research to come past then you come back to the research. So it’s a back and forth. Hard to stay on top for anyone. Just the name of the game.

@@MesaMinis it’s recommended .. but some people “don’t cut the block” and they say it works just fine. Ehhhh.. But I’m a perfectionist and if the bracket has a thickness I’d want to take that thickness off just to get it back to stock position. Sucks we have to do anything to these engines to get more power out of them lol .. wish they just came 30HP out the box lol .. well you could get our crate engines and that solves that hahaha .. everything good comes at a cost. We just need to think if that cost is something we can live with. Me personally, being an engine builder and boring and sleeving engines all day to get more power I love to do the work.

@@aussiegrunt2117 well so far we found 80mm is the biggest you can go. Bolt holes are the biggest issue it’s actually a very complex build setup. The 300cc tested out at 45.6 hp untuned , looking at fuel curve and where timing was there is an easy 10 HP left in it. Timing was at a safe 35° and at this level a degree of timing is about 3hp. Prob wants 39° and carb was very rich .. was just a safe test of power. Haven’t had any down time to do more tuning on the shop beast but it has lots of room to grow.
