Thread: Did I buy a 428 and get a 390 Thunderbird?

I guess what is being said is: Yes, the stroke measurement needs to be accurate, all agreed. But that asking a micrometer to find almost a quarter inch and not much less is a tall order. I do see your point and it is well taken, believe me and very much appreciated. I WANT to sympathize with him in a sense because I want it to be right- a 428, what I bought. And since I paid just 2200 for the car, it won't be the worse loss I ever suffered. If it has a 428 crank, and a 390 block, I feel the thing to do would be to "correct" the block if possible. Whether that means buying a new one, or boring if needed. I do not want to be annoyance being new at being on a forum, so I try to be intelligent in my questions and refrain from mentioning too those little black crumbs that drop on my face ruin my make up. I was not at all into engines, though my father was a rocket engineer and I married a motorhead biker and after all this time I thought- if you cannot beat them, join them. So I did- IN FULL force, and now I have made a terrible mistake in the car I am afraid!

can i ask why you think a 428 is so imporant? are you going to build a nice motor for it? Are you wanting to build a cj?

I am an old Ford fan recently converted to SBC thinking so it is great to see the Fordnatics come forth with tech stuff. It seems to me that "afanoni" is a lady who writes well and she is to be encouraged, I can't get my wife into the garage unless it is to look at some clean new piece of stainless beauty and I catch a lot of heat if I don't wipe my feet coming in from the garage, so I can understand why she might not be receptive to a relatively easy process of pulling the crankcase pan. That is surely an easy but quite dirty job. Still why be upset over a repairable T-bird that only cost $2200? That sounds like a good deal to me if there is minimal body rust. If it is a 410 and you can clean it up, get it painted and fix the interior and enjoy it. I don't understand the difficulty of micing the bore depth, the local shops I used to be familiar with would send a guy with a few different micrometers to any garage contemplating an engine build to at least indicate out-of-round cylinders and what is so hard about finding a depth gauge micrometer? It should be possible to find a shop that will do this for a very small fee and your mechanic should know who to call? So why not pay the mechanic to pull the pan and ID the crank or find someone with a depth micrometer?

and MY favorite machine is a 1922 Steinway model O grand piano. But as I said, I could not beat them, so I joined up. I do find that a scholarly approach to the would be 428 Thunderbird project is needed. The "engineers" around here are a little quick to write it off as a 390, I shall continue to enlist the help of you all if I am to be included- again with many thanks!

Hey ................ mmmmmmmmmm, not sure how to approach this one. But here goes. You bought the car so you could have FUN right, so no need to think you made a mistake, think of it as a challenge, you obviously took a big leap into this and are asking for advice,fair enough, thats what we are here for. "Me", I admit Idont know a whole lot about Fords, I am a Chevy man myself, but there are plenty of Ford men here. But one thing I do know with my passion/hobby is how to have fun.

And in hotrods and cars there are many ways to achieve having fun as there are guys and girls twirling wrenches and it is a great learning curve too, with people as well as cars, and, okay I will throw in learning new computer skills as well. I have been with engines ever since I was 3 and I am always learning something new any number of ways. Sure there are some days where things dont go right, but it wouldn't be a challenge then would it ? What else ? oh it will cost money but if you spend it having fun, it's well spent in my view. You only have one life so make the most of it. Well I have said my bit.
