Originally posted on motor swap:
Well, the venerable 305 has now gone and has been replaced with a 4 bolt 350 with 9.6:1 compression, the 255 hp truck cam, and new heads, (NOT LO5).
The car has only a couple of hundred miles on it so far, and runs like a raped ape.
The low / mid range surge of torque is really impressive.
Nothing else has been changed. I am still running 19# injectors, and the stock ECM and chip.
Question, should I change the chip, and if so, to what.
Also, am I doing any harm running it as it is.
There is no sign of detonation, or running out of power until past 4500 revs, so the tpi starts to run out of steam.
Any help gratefully received.
Does anyone have any ideas?
The engine basically is the 255 hp truck motor, which produces immense amounts of torque. I feel this is what the tpi is designed for and would appreciate any comments.
Cheers

I'm a tuner.
I'm never happy.
I want to go faster longer and use less fuel.
I want instant response.
I want I want I want

The injectors/chip and motor are ill matched, and you can either get a custom chip to make the best out of what you have, or get the 22# injectors and a 350 chip. Or you could get the 22# injectors AND a custom chip, and it will be a raped ape on steroids!
