Hi im trent but i go by tbone3366, my friends miata 1990 has blown its 1.6 and i have a spare 300 i6 and she wants to drop that in place and wanted to get as much info into the swap as possible, here are the dimensions for the big block, FRT-FACE-OF-BLOCK to REAR-FACE-OF-BLOCK: 725 mm / 28.56"

OAL (FAN-to-CRANK-FLANGE): 931 mm / 36.65"

HEIGHT CL CRANK-to-TOP-OF-BREATHER-CAP: 486 mm / 19.12"

HT OIL-PAN-to-TOP-OF BREATHER-CAP: 690 mm / 27.17"

and finally at 490lbs fully dressed, will be doing port efi setup with a custom intake manifold and exhaust

 

If someone challenged me to choose the worst engine to swap into a Miata that would be near the top. Good luck tbone.

 

thank you, its my friends fault for wanting it after i made a custom exhaust for my 83 f150 and showed how rediculous it is with efi and a nice mid range cam....
