1992 issues

i recently did an engine swap, v6-v8, i did everything right, put the v8 throttle body on and everything..yet the truck always wants to stall..

it's a 92 1500, 5 speed..had the 4.3L, now has the 5.7L(stock)..i put the v8 computer in it..i believe i did everything right for the swap, but cant figure out why it keeps stalling, and also lacks power..

anyone have any ideas?

thanks!..Daryl

Have you got all the emission stuff- egr valve, solenoid, map sensor, ect sensor, o2 for the 350. Did you set the timing with the tan wire disconnected?
