| I was refering to the all aluminum LS1.  I believe the iron block engines 
are LQ4 and LQ9.  I haven't been able to find reliable weight numbers for 
the LS1 or the 215.  A couple websites list a manual transmission LS1 (and 
LS6) as weighing 497.2 lbs.  That sounds heavy, like it may include the 
transmission as well (especially since the weights are different auto vs. 
manual). 
 In any event I hope you are right - because if the LS1 isn't that much 
heavier than the 215 (or the 1800) then it should be a good engine 
candidate.  I also looked at the Northstar but the parts are expensive vs. 
the LS1.
 
 There are several LS1 Miatas floating around the net - cool stuff.

 Chris,Are you talking about the iron block LS1?  I don't remember the exact 
numbers, but the weight difference between a 215 and all-aluminum LS1/LS6 
is far less than 100 lbs.

 Hi I'm Chris in Atlanta,
 Is anyone working on putting the LS1 in an MGB?  I like how light the 
Rover engine is (300 lbs. correct?)... but I'm thinking the LS1 without 
A/C or power steering is going to be around 400lbs (vs. the 1st generation 
small block Chevy  which is over 500 lbs.).  I've done quite a bit of 
searching but haven't found anyone doing the swap (yet).  LS1s/T56s are 
plentiful as well.
 
 I gave my brother my first car, a '77 MGB in sandglow.  He's just letting 
it sit so I'm thinking about getting it back.  The 1800 ran fine before 
but I think a V8 would be more my speed (my other projects are an '80 El 
Camino with a 406 SBC / Doug Nash 5 speed and a '68 Chevelle SS396).
 
 Thanks!
 Chris
