Radiator and fuel pump upgrade for LS3 427? Soon, I will get this build for my CETA. It's coming from Scoggin-Dickey. So I was wondering has anyone here with this setup upgraded their radiators and fuel pumps or ran with stock ones? I got a new fuel pump and assembly cause the original one went out on me. The new fuel pump is OEM though. So should I run with this new OEM fuel pump or bite the bullet to upgraded fuel pump? Thanks.

I am getting ready to put a 403 in my bird and am upgrading to the racetronix w/ the hotwire kit...You will prolly need it more than me... I already have a dual 1" core Howe Racing Enterprises radiator and in my climate it is totally necassary IMO......

So this racetronix u speak of...it's plug n play and no modification required for it to go in the tank? How much is it? All I need is the pump and the lines to the feul rails. I will have FAST injectors and rails. I live in GA so I guess I should upgrade the radiator too. But I will be able to read the engine temps to see whether or not I really need to get a upgraded radiator.

Yea it will drop right in. The hotwire kit runs the pump off the battery so you don't get voltage fluctuations meaning a more constant fuel pressure. My 346 ran +230* temps A/C on in traffic after my H/C/I went on so that is why I upgraded the radiator. Never over 200* now.....

True but only by 1/16th or may be an 1/8th....... I looked into it before my swap but honestly can't remember. Honestly in GA. I am betting he will need it.... Mine has a 160* stat and in summer still hits high 190's-right at 200* with both fans blowing....
