So the deal is my 1990 dually was a 454 truck that was swapped to a 350 when the 454 blew up before I acquired it. I then had the truck a few thousand miles and ended up blowing a head gasket between cylinders 3 and 5 leaning the engine out... contemplated rebuilding the top end but then got a killer deal on a 1989 Winnebago chieftain with the 454 in it with only 27xxx miles and ran and drove great! pulled the trigger on it for 1600 bucks and went to work on the swap.
its a carb 454!
I will post pics from the swap later for you guys but I need help as to a few issues I've run into along the way...
1. gas tank was bad in my truck so I yanked the 55-65 gallon tank out of the Winnebago and am in the process of mounting in the front of my box, dilemma I'm running into is, if its the slightest bit above the carb, could that cause a gravity feed or syphoning condition and pull fuel from the tank and through the quadrojet and flood the engine when truck is not running? I only ask because I was told this could be an issue and it frightens me to possibly have to deal with this on a business investment vehicle... I need reliability.
2. I've deleted all the emissions crap and I want to eliminate the smog pump from the serpentine belt, along with a new alternator bracket because the 454 one hits the hood. should I just cut the old belt, wrap it around the new pattern and measure it to get an accurate length on what ill need from NAPA?
3. what will be ideal exhaust for a bone stock 454 with long tube headers? I'm going duals probably with an H-pipe for TQ but I don't want to go too small or too large. the engine is freed up from all emissions crap completely and I want it to run the best it can
all input is needed and especially input on #1.
if you have any suggestions into making this even betterthan I am this far, feel free to chime in as well
