Re: My 70 swb has a 327
CC69 rat you know I can talk about bondo all day but I have never been one to follow or have an indepth knowledge of the casting numbersand what then mean and witch one are the ones to have. So I don't have any idea what 041's are but I think I remeber 186's to be early 70's heads? I have a set of fresh heads that I took off of my 70 model 4 bolt main 350 that I replaced the heads[never run since rebuilt] with vortecs. I may dig them out and check the numbers on them
