| RE: .80 over 390 = 406==help |

So what are you building? A 406 replica? You must have a need to make this a 390/406, right?
It's tough to advise you to go ahead and bore that C6ME-A block .080 without having it sonic tested/mapped. The markings you indicate "may" make it a great candidate but how do you know? Look at the thread right by this one about taking a '70s era 360 block out to 4.13 bore. You just can't tell.
And as for the 391 FT block. Again, it's very likely that it's also a great candidate. But I would still want it sonic checked. My 391 FT block is a C6ME (No A or other markings like yours). We found the little tiny 428 cast numbers visable through the middle core plug hole. I still had it sonic checked/mapped. Because of what we found, it's now bored .030 over 428. I have the Ford distributor bushing. It should make a great performance block.
So you're going to run the 352/390 HP heads, COAE-D? With the other '61 HP equipment, it sounds like you're building the 401 horse replica.
I've done something somewhat similar with a '63 427 block using all Ford parts to make a pseudo 352HP. I can't hide the cross bolts but not many will know to look anyway. Those who do look deserve to know the truth. They're FEnatics like us! |
