1985 454 swap

[rwilhi]

Swapped to 454 in my 85 Scottsdale..now need California emission components.. anyone versed in what is needed? I was told that i should be looking for emission parts from a gas dually since the mainly run 454. Is this correct? Truck had 5.7 previously, but neighbor had a 85 motorhome that he had parked on side of his house and used as spare space when he had guests and it only had 15k miles on it. I was able to get his engine when mine threw a rod. Any help would be greatly appreciated
