Im going to swap out my junk 305 TBI and drop in a LT1 from a 94 Z28. Im wondering what parts i will need to change and what i should take off the 94 maro?

 

You will need a new fuel pump. Get the 94 harness and computer. Save yourself some hassle and get the 94 computer reprogrammed for your needs and delete the VATS crap. You will need to address the fuel line connections. I myself purchased new lines from the wheel well connection to the fuel rail with LT1 specific rail connectors. One question, are you keeping A/C or not?

 

no im not keeping A/C, it doesnt work now so im actually pullin it out tomorrow, i heard its a pain in the *** dropin in the LT1 with it so i just will take it all out.

 

What transmission are you going to run?

 

will my 700r4 bolt up to it? if not ill just get the one out of the donor car.

 

it will bolt right up

 

hehe, im hoping the guy at the shop thats doin it is right, he says he can doit it all in 1 day and have it runnin perfect, i not sure about that but hey if he can thats awesome, wish i could doit myself but i dont have the resources to doit and hes gettin me a mad deal on it 750 for motor and 250 for labor

 

if youve done it 100 times and knew exactly what you were doing, 2 days would be a estimate for that. its the sheer number of details to take care of thats the problem


if you arnt 100% prepared beforehand, id say thats impossible.. i mean, you would need the wiring ready, the fuel line adapters made, ect.....

 

How will the 1994 ECM/PCM deal with a non 4L60E tranny?

 

All it will do is the TC lockup.

 

Could you elaborate more?
Is it a problem?
What is involved?
