geant90 Posted June 24, 2014 Share Posted June 24, 2014 So I am finally a 2+2 owner! In a few weeks I plan on purchasing a LQ9 to rebuild. I initially was going to go with $500 LM4 but decided I want more displacement. I got my eyes set on a LQ9 but with the iron blocks being around 70lbs heavier I would like to know how would this affect it. Anyone got input especially those who bothered to pull out the AC to save weight? Would keeping the AC and fitting a LQ9 mess up the handling and weight displacement? I do intend on installing power steering as well so I want to know if it'll feel odd especially with the larger wheelbase of the 2+2. Also it will not be a stock LQ9 I will explore maybe even aftermarket intake manifolds and if I do not clear the hood then things shall be cut!

SUNNY Z Posted June 25, 2014 Share Posted June 25, 2014 Iron blocks are closer to 100# heavier. I say split the difference and get an aluminum 5.3. Better engines overall as well, and will likely be found with less mileage. Quote Link to comment Share on other sites More sharing options...

RebekahsZ Posted June 26, 2014 Share Posted June 26, 2014 An LS 2+2 sounds like fun, like a reverse mullet: business in the front - party in the back! I wouldn't worry about the weight distribution if you are determined to use a 2+2. Just have fun with it. Put a huge hood scoop over that truck manifold and let 'er rip!
