the 49 is all original i thought about using the rear end the th350 and puting a mouse in it instead of the flat head so what ever is stock in a 76 camaro except it has a 6 cyl in it so probably need a torqe converter??? dont think ill clip it either i guess what ive read about early plymouths IFS, it wouldnt be needed at this point !although tangos got the idea!!!
