Hey all! Just started researching for our big project. Right now I might have a bead on this guy... A 1990 Chevy, 454 gas dude. VIN says it's a B6P402. $2500.00 still need to find out milage. A church owns it. Thoughts? I'm aware a Diesel, T444, or 466 would likely be better, but the price is attractive.
I got the 366 Big block and it rolls 65mph no problem, i bet that 454 is superb!
Love a motor with a carburetor, alternator, and distributor. Not difficult to tune up
ps. It is uncommon to see the 454 in a bus...
when I had my 454 with it stock and the 2 barrel i got about 3 MPG average in a short bus...
after I put in the 4 barrell I went up to about 4 MPG... (a properly adjusted 4 bbl will get better MPG than a 2 bbl.. as tyou run the front 2 lean but let the secondaries come in a little earlier than would in a performance application)..
after RV cam, true dual exhaust, flowmaster 50s and 4 bbl and ignition upgrade / bosch platinum plugs id get 4.5 or so.. that was driving 65 on the highway... that bus had what i believe is an AT545... acts just like the trans in my current bus.. I never payed attention to the trans since it worked..
when I drove my bus spirited and got loud i got something like 2 MPG or so lolol...
im not sure what my TQ / HP readings were for sure but i know it was alot of fun to kick it to the floor and sounded good too..
P.S. that bus was more fun to drive than my current bus but on long trips my current bus rides so much better and gets much better MPG's..
