My buddy has a 78 F150 with a 351w and he is planning on intalling a new long block. My question is, would a 270,000 mile motor (specifically the block) be worth using as long as it hasn't already been bored and doesn't have any cracks? If so, I plan to buy it off him and put it in my 88 GT. Which brings me to my 2nd question. I'm helping him look for a long blocks. Are there any builders out there who sell 351w long blocks in the neighborhood of $3000-3500? Any links you could give me would be much appreciated.
As far as finding a 351W for that price...Sure...There is always EBAY!! SEHR has a 351W long block for $3699-$4099 (their site is http://www.sehrpower.com/fordsr.htm). Check out http://www.enginefactory.com/351W.htm too. For $2499, http://www.cdpautomachine.com/ offers a 350HP longblock.
a high milage truck block is usually preferred for many people. it is "seasoned", meaning that it has been subjuct to many heating and cooling cycles. this makes it a good candidate for a hi-po rebuild.....
I would give it a shot. As long as you don't have to go past past .030" overbore you could have one solid block for a foundation to build on.
