Guest GreenZ Posted January 28, 2003 Share Posted January 28, 2003 I came across a 96 LT1 with a 700R4 trans today, complete with harness and computer. I was wondering how much heavier this engine is than the L6 and how any problems I might run into vs. running a regular SBC 350? I would like to install this engine into my 77 280Z instead of the turbo engine I have laying around. BTW, the engine is $700 and runs fine, it just didn't make enough hp for the guy who is selling it. Is this a good price? thanks JB Quote Link to comment Share on other sites More sharing options...
Len Posted January 28, 2003 Share Posted January 28, 2003 That's a very good price. Weight difference of a standard 350 SBC if I remember was about 150 lbs. heavier than L-28. Now the Lt-1 has aluminium heads which should lighten things up while the added weight of turbo will increase weight of L-28. Len Quote Link to comment Share on other sites More sharing options...
Mudge Posted January 28, 2003 Share Posted January 28, 2003 I dont like automagics, but $700 is a pretty good price. Remember the V8 sits a bit further back, so its not all going to be "crappy" weight in the Z. Quote Link to comment Share on other sites More sharing options...
Modern Motorsports Ltd Posted January 28, 2003 Share Posted January 28, 2003 LT1 sits nice'n'low with excess hood clearance and fine balance in the Z IMO. Great candidate for install.....their is some issuse on AC or PS pulley to be navigated so it clears your pass. inner fender but it's been done by a few now so new rocket science required. I know it's a VERY common discussion but it's no longer even a thought for myself (weight of L6 vs. ___) as my 280ZX came out with a slight rear weight bias/my dad's 240Z is likely the same/both handle great with neutral characteristics. L6's are so far fwd in balance a nicely placed V8 swap with reasonably light components go a long ways to having a great setup, 100-150 lbs (even if it was that much, mines lighter than OEM with nothing else stripped) is very minor given the power/tq gains! We've both got upgraded suspension/brakes/powertrain/R200LSD etc and can't cite any notable hybrid flaws. Here's my dad's Lt1T56 240 (Ron Tylers 'old' powertrain) with a few pics to help you see fitment. At some point he'll do a cold air mod. FWIW, the louvred hood vents made a HUGE difference in engine bay temps and allows hot air a much easier exit (he has un unvented OEM style hood).

Len Posted January 28, 2003 Share Posted January 28, 2003 Ross Your father's fit of that Lt-1 is awhsome! Someday I'll do more than look at my 96 Lt-1/T56. Right now I've got a commitment with my son and our 70 Firebird. Is that a griffin rad.? Did you have any issues with the reverse cooling?Didn't look like your father installed either (the air cond. or Powersteering ).....Really as I mentioned before a turbo L-28 will be a bit heavier (than stock L-28)and a Lt-1 will bit lighter(than stock 350 SBC). I figure they will both just about equal each other out and be real close to each other weight wise. Quote Link to comment Share on other sites More sharing options...
Mike C Posted January 28, 2003 Share Posted January 28, 2003 You never said if your motor was from a Camaro/Firebird, Corvette, or Caprice/Roadmaster. The F body and 'vette motors will have aluminum heads and be another 40 lbs or so lighter than the iron head motor. And hopefully it is for sure an LT1 and not an L99?
