LT1 radiator in LS1.. worth it? ok well i have a 2000 trans am A4 and live in FL so it get hot as hell here and since its cool now i want to get my car ready for the summer, i dont have the money for like a griffin or becool radiator, so that said i already have a huge external tranny cooler, lower temp fan setting 187 on 180 off (180 stat)
, i have heard that an LT1 radiator is a bit bigger than an LS1 rad. i can get a new LT1 rad for $130 but will it make a big difference or at least a difference not even worth doing it, and if it is whats involved in doing the swap.... thanks alot in advance

Verdad Gallardo I have only used an LT1 Rad since that is what I had. biggest difference I saw was putting the stock dual fan on there rather than the 12" fan I was using...but i still have the stock thermo and it gets warm idling in the staging lanes....
however pelase remember modern cars are made to runner a bit hotter. That can be tuned out by changing when your fans come on and off or with a manual switch. Your fans stock are set to start comming on at 212*
The biggest reason I went with something other than stock, is the fact that my stock radiator failed in the first place because of the plastic on the stock radiator... what ever I upgraded to, I wanted to make sure it didn't have any more plastic anywhere on it... that **** cracks and spews coolant all over the place... if your not paying attention then bye bye engine
