scottydoggs Posted December 14, 2017 Report Share Posted December 14, 2017 only reason for that is to make room for a turbo. you put the battery in the trunk of rwd cars for the weight, fwd cars kinda need the weight for traction that it still lacks. no gains, only the loss of funds from buying all that cable and battery tray.

Imp558 Posted December 14, 2017 Report Share Posted December 14, 2017 The old-school hot rodders put the battery in the right rear to distribute the weight a bit better and help offset the weight of the driver on the left. Have to keep in mind all front engine cars are nose heavy. A 5.3 is just the most nose heavy example of a W-Body. Every car can benefit from trunk mount to a point. I don't think I'd want to add useless weight though. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted December 14, 2017 Report Share Posted December 14, 2017 A 5.3 is just the most nose heavy example of a W-Body. I'd be shocked if an L67 didn't weigh DAMN close to an LS4 if not more. Quote Link to comment Share on other sites More sharing options...
scottydoggs Posted December 14, 2017 Report Share Posted December 14, 2017 my dead l67 minus the blower and lim and pulleys was 330 lbs on the scrap yards scale. Quote Link to comment Share on other sites More sharing options...
digitaloutsider Posted December 14, 2017 Report Share Posted December 14, 2017 That seems really light, even without the blower and LIM. What else was missing? Wikipedia suggests an L36 weighs 400 lbs dry (i know, wikipedia..). Scrap yards aren't known for their honestly-calibrated scales, but I could see that for JUST an L67 block and heads with no accessories, no exhaust, etc. The only estimate I can find for an LS4 is approx 475 lbs "without a PCM or power steering pump", but I don't know if that counts exhaust manifolds/crossover, too. Fully dressed they have to be within spitting distance of each other. Quote Link to comment Share on other sites More sharing options...
scottydoggs Posted December 14, 2017 Report Share Posted December 14, 2017 stripped down block and heads i needed everything off the front for the new bottom end being it was a l36 or maybe 330 was full weight, and i was 30 lbs under it? it was over 2 years ago now. seen a pic of a complete 3800 on a scale. that might have been the 330.

Imp558 Posted December 14, 2017 Report Share Posted December 14, 2017 At any rate a good sized battery weight 40 - 60 lbs and that's before the box and cables so there's merit to the concept of transferring it to the rear of the car. For drag racing it wouldn't be a good move but for handling it's worth it. The biggest reason I moved mine was that it was in the way of my CAI.

KnightOwl Posted December 15, 2017 Author Report Share Posted December 15, 2017 The drive home from PA went well with no breakdown (YAY!) no rattles, buzzing, or things not working. The ride and feel is definitely not that of a 15 year old car. After the 240 miles trip, I did notice a slight burning odor but a check under the hood showed no smoke or signs of anything leaking. I assume it might be spray dressing or something that was used to clean the engine bay at detailing for the dealer. I must get my 2013 Taurus sold before I can really dig into mods or upgrades, but for now it looks like I got a solid machine. I also forgot how buzzy/raspy sounding the stock exhaust is on the 3800 engine...but that will change! LOL If there is one thing I got plenty of experience with on my 2001 GP was finding a set-up with good sound and no drone. Imp558 1 Quote Link to comment Share on other sites More sharing options...
Marshal Posted December 15, 2017 Report Share Posted December 15, 2017 I read someplace that an LS4 weighs like 60 lbs more than an L67 Quote Link to comment Share on other sites More sharing options...
