383 Into Stock Slant Six K Member?

Slugger8985 said

I'm planning on buying a 383 to replace the slant six my 66 Valiant came with. Will the stock K member be able to hold the weight of the 383 with replacement motor mounts or should I try and find a big block k member to replace it with?

yup the slant k-frame will hold just fine. your problem will be headders. no one make them for an early a-body. i had mine custom made when i did my 64 valiant. had to make my own mounts too because that was before schumacher and street master made them.. i say 440. may as well start with the biggest cubes.
