Ducky will have to chime in on this one.

FYI - He finally gave up on the 4.3 and swapped a 5.3.

thats my plan swap to a 5.3 but i got the qoute for a 5.3 with every thing $1500 or rebuild my six with hopped up parts the works $1500 but if i do put the 5.3 i need the bell house and bigger fuel pump. so if i do rebuild with a live tune will i hit the v8 power or is it a waste of time and money? need help here

[SCIV]

Waste of time and money IMO to stick with the 4.3. Unless you are just out to prove everybody wrong and throw craploads of money at it.

i see you would take a 5.3. my case is my 4.3 is on the way out its got blowby the motor is losing power i got money in it but the parts i ve use have done nothing. i thinking 5.3 to

[ducky]

I would def not waste money on the 4.3 and just do the 5.3. You can do the tune though. I got better MPG and was able to hang with roughly stock 5.3 ext. cabs

[smoke118]

so your power gains were there just not as much as the 8 thanks for your input

[ducky]
