fuel pressure & radiator 4.3 to 5.3 ?

[moldmaker]

Does anyone have any info on whether the '02 4.3 radiator will cool the 5.3? How's that 4door Blazer cool with the LS1? Is there a difference between the fuel pressure of my Vortec and the '02 5.3? I guess I will probably have to upgrade the fuel pump anyways most likely. How about fan clearance?
Any comments anyone?
I'm sure many of you have seen this but there is a video or 2 of an 02 blk S10 PU with a 5.3 & NOS

Looks like he high mounted his AC upper pass side. Hmmm

depending on the year of the vortec, it should be fine fuel pressure wise. check it. if its around 50-60 it will work.

The pump is fine, Use the corvette filter combo and your golden.... The blazer cools perfect and I am building a beater truck with a 5.3 and 4.3 rad right now and will let you know how it works out soon!
