This is the difference in who you get to build your crate engines.
We contracted Proformance Unlimited to work with us in building the 408 Injected Roller Windsor for the XY build for one reason.......experience!
There have been literally hundreds of "Crate Engine" companies starting up since they became popular 🙄 but nearly every one of these are simply "fitters".....they just assemble a heap of parts out of the box and bolt everything together into something that resembles an engine 🤔 Nothing is matched, inspected, measured or tested......you get it in a box bone dry and just prey it all works.....which 9 times out of 10 they don't !!!
This is where crate engines got their bad reputation, from these types of pop up builders with no experience trying to cash in on a lucrative market 😡
We chose Proformance for their 30 odd years of experience in this industry and worked with them over many 2:30 in the morning personal phone calls to Doug and the staff the whole way through the build to plan, discuss and modify components to get exactly what WE wanted, not some catalog engine. Even through shipping and customs dramas they were there the whole process helping out from their office in New Jersey to make sure everything got sorted 👍
Their customer service and backup has carried on long after they "got our money"
The 408 turned out a great engine and came with all parts receipts, build pics, dyno sheets and even a video of it's dyno runs😁
Won't get that from any of these internet crate builders !!!
I highly recommend Proformance Unlimited to anyone looking to build their own crate engine 👍
