Yes, yes I do.
I know it's a stupid swap and the ROI on an Exploere 302 is tons better and that swap is much more documented but I have a bunch of 300s around and I like them.
A couple people have done it. It's bad but not a terrible swap. Basically you spend all your time fucking with the core support instead of fucking with steering/exhaust/hvac to clear a wide engine. I'm probably gonna wind up tilting it a bit to move the EFI lower away from the HVAC which has the side benefit of moving the shifter toward the driver.
