TBI to TPI HELP PLEASE
I am currently the owner of a 1989 Camaro RS 5.0 5spd. I want to convert the car to a 350 TPI or build a 305 TPI. I baught the TPI unit with all strings attached with ECU and wiring harness for really cheap with a 305 motor. Just curious but does anyone have any instructions as to how I should go about changing out the TBI to the TPI motor? Is there anything special that I have to do or just rip the computer from the old motor out and put the new one in? Would it be more worth while to keep the motor with the TPI or can I put the TPI and heads on a 350? And if I did that would it work out with any block or only L98 blocks and newer? I would be very grateful if someone could walk me through the procedure of putting the TPI 305 in because I would much rather build a motor with a matched intake than trying to mix and match it. Any ideas on the build up would be nice too.
It all boils down to if someone has the directions that I can purchase or they could just tell me
?
Would it be worth it to stroke the 305 or would that not be worth it? should I just put the TPI on a 350 and get a used ECU off of a 350? or could I even put the TPI and heads on a 400?
WHAT SHOULD I DO GUYS PLEASE HELP ME. Im an amature and there are way to many options for me to go out their with and not a whole lot of knowledge. I know how to build motors I just dont know about all the TPI computers and all that.

i am planning on doing this swap myself in the near future, and my concerns are the wiring and the throttle cable.
the tpi will fit on most gen I sbc. you don't have to use the heads, as 305 to 350 the bore is different (so it wouldn't work very well)
i would suggest that if the 305 that you have is in good running condition, use that, since everything will bolt on. and you can use the same ecm and injectors, then prepare for a 350, and then you can get a custom burned chip and bigger injectors (305-> 19 pph injectors, 350 -> 22pph injectors)
hope this helps a little, and hopefully someone knows the answer to the wiring and throttle cable question
