2.8 v6 to 5.7 v8 TPI (1988)

I have a 1988 camaro with a 2.8 v6 and 5 spd tranny. What i was wondering was what i would have to do to convert it over to a 350 TPI. Will the factory tranny handle the bigger engine? Do i have to change over the engine mounts? Do i have to change the wiring harness and if i do, where can i get one, i've heard they are hard to find. Is there anything else that'll have to be changed over? Your input would be greatly appreciated.

theres alot of stuff you need

-full engine harness, every relay, everything you can possibly get, get it

-the ECU

-fuel pump

-the ENTIRE engine, air intake, im not sure, but youll probably need a new y-pipe

-im not sure about the tranny, id hate to chance it though

as for the rear, its a 10 bolt open rear with 3.42's *i think*

the L98 swap is no easy task, there is alot of extra wiring you might have to do by hand, my friend and I had to run the injector trigger wires to the injector harness, alot of senders and sensors might have to be rewired if you dont get the ones for that specific engine and year

I used to have an old 2.8 liter car and considdered the swap. When I saw the price I realized it was just cheaper to sell the car and buy one with the motor I wanted.
