Well,you got your work cut out for you.You will have to change the oil pan,or cut on the a frame for oil pan clearance,change front suspension the stock will be to light weight for the BB.I don't know for sure but you may even have to cut the firewall,I mean my 350 is pretty tight already and not much space for fan and water pump.I can imagine a 454 and yes you will engine swap hedders I think I could stand corrected.Ive gone SB to BB and is a headache but if you get it done you got yourself one bad SOB.Good Luck

 

Your going to need 3 gas cards to keep that hungry baby fed!

NOT!

If you've done a 406 poncho into and 89 the 454 will be about the same except you can get the parts easier. Don't use the hookers, use the sandersons. They're about $100 cheaper and won't require a 4lb sledgehammer to get them to fit. CrazyRob75 used the stock manifolds and I use the hookers last time. This time I'm going to get the sandersons. You can use stock truck exhaust manifolds but, the power increase won't be the same. The engine mounts will be fine, you can even use the stock 305 pieces on the frame side (I did, they sit lower to the frame).
