350 to 454

[bucket]

it will run with the 350 chip but it will be way lean and not run right I wouldn't do it that way.

I was just saying the tbi will work on any stock cam or mild cam 454

Ok. I kinda wondered if the calibrations were similar, since the larger motor also uses larger injectors to make up for it.

I have also heard that to use the mechanical pump that all you have to do is disable the elec. pump and redo the supply lines which you will have to do anyway if using the carb. So I guess that leaves it up to you as to which way you want to do it. I think it would be cheaper to go with the carb.
