LS7 vs. LS3 physical dimensions?
I always thought that the LS3 and LS7 shared the same physical outside dimensions. I'm looking at a new project and the newest ND MX-5 Miata seem nice. I have an LS7 crate engine today so I spoke to the guys at Flyin' Miata, who normally use the LS3 for their swaps, about using my LS7 and got this answer:
The LS7 isn?t the same size as an LS3 (the crankshaft is physically larger diameter), and there?s really no place to put the oil tank up front on the ND. It would be a challenge but I?ll bet you could tweak the rack location and make it work if you really wanted.
So what about the larger crankshaft diameter? In what way does it affect the physical outside dimensions of the engine?
I could always get the 376/525 LS3 crate as they normally do but I really like my LS7 and would prefer to keep it, it's a rather special motor.
