I plan on putting in a new cam and heads on my 305. Of course I'll get a new chip to make it run as well, but if the bottom end gives out on the 305 and i replace it with a 350 or 383 block(more cubes) will i need to get another chip? I would still use the same cam and heads from the 305.
I hope that makes sense.

 

Yes, you'll need a new eprom for optimal results. Any more questions?

 

Nope, thanks. What a bummer tho'.
