autozone crate engine
 

i am thinking on buying a 351m rebuilt from autozone for my 79 f-250 any sugestions

If you're looking for quality....look somewhere else.... x(

Some people may advise you against this advice I am about to give, and if someone has more recent experience, then you should not listen to me...

I bought a motor from City Motor Supply in Dallas 9 years ago and it has always been very strong and run well. I was going to do the same thing again, but some people advised me against it. I don't know how they are now, but I can tell you for sure that they used to build a great motor, stock-wise. And for a short block, you would only pay $350 for a 351m.

Either way, I think that CMS would be better than an Auto Zone Engine.

I'd get a price from a local machine shop to compare. Also I'd go for a 400. It's all the same on the outside.

thats what I am doing....going with a 400 crank and 400 flattops. The rest is stock in the bottom. and yes, you are right, the machine shop building it wasn't much more than buying a stock one. prices are much better than they were a few years ago.
