So whats the don'ts on this? It is going in a 92 350 crewcab. It'll have a mild cam that I've used the same grind in a stock fuelie and worked great. I also have tri Y headers and a k/n for it also. Just lookin for more torque in the towrig. Is there any other mods that maybe required like bigger injectors or will the stock handle it?

Thanks

You may run into problems caused by the speed density set-up, may want to convert to a MAF intake system

In the early days of EFI, and especially in imports where EFI came out in 1970, it's been proven that as long as you have similar vacuum at all loads/rpms, as you did stock, you can do a lot by upsizing injectors then fooling with adjustable resitance in the coolant temp sensors. Not 100% right but sometimes nearly as good as the OE clibration of the early stuff.
You really need to understand EFI theory though
