Is anyone out there running a 377 SBC? If so how do you find it?

I understand American Speed have sold a few ...

What would be great is if anyone is running one on EFI??

thanks

G-Man, the owner of the original record breaking car has a 377 motor installed in his GTR, albeit a carburetor engine, and that was the way I was originally going but in the two years that it took to have my mill built, had changed my mind and gone for a larger displacement 'because I could'.
On paper, the 377 has all the right credentials. Not a torque monster and so is kind on the transmission/clutch and associated parts but will happily rev to 7,500rpm and makes good horsepower. G-Man has 18 degree heads on his lump and for this you will need different headers but well worth it in the long run. If you are seriously interested in this format, PM me, I have some information + that WILL be of interest/help to you yes

377 is a destroked 400

three are 4 options for destroking

302 and 327 for 3 and 3.25" stroke for the 350 block

and 321 ansd 377 for the 400 block for 3" and 3.5" stroke

321 is real rare and the the highest reving option but revvy small blocks can have breathing problems
