305 TPI to LS1 converstion Question
Hey Guys,
I have been doing a ton of research over the last few days, and have not been able to find the exact answer for my question
I have an 87 GTA ASC Convertible that i was just going to freshen up the 305 and be done with it, but i figured by the time i got done with rebuilding the bottom end, adding new heads, cam, intake and gaskets i would be in for pretty much the cost of an LS1, however i am wonderinf if anyone has performed this swap on a digital dash car or knows if this can be done. I have see that most or all have been done on the analog cars.
I am looking at doing a 99-02 LSI +T56 swap.
If anybody can point me in a direction that would be great

I may be wrong about this, and if so, I will accept correction.
But, there shouldn't be any differences vs. analog. You will need to correct the tach output for V8, just like you do for analog, but everything else should work.
