I have a 95 mustang 5.0. the motor is all tricked out from cams to heads, and powerdyne supercharger. what i want to do is build a 347. but i want to do it the cheapest way possible. i want to get the block from the junkyard and then bor and hon it. but what year of the 5.0 has the strongest block.

 

also i want to run fuel injection

 

a Bos 302 is probably the strongest, yet heaviest also. [8D] new block wise....if you want something strong........id say the '89-'92 cuz they have forged pistons, so, the blocks MIGHT be a lil stronger, yet, im saying all the '87+ 5.0 blocks were the same. OR, if you got the money......get a Dart or an A4 or Sportsman block from Ford Racing......although.....for some reason....i think 2 of those 3 are the same thing. oh well. good luck though. sounds like itd be a sweet ride. im gonna b doing a built 306....so, we in the same boat. haha

Edit: AND the Boss block will also be the MOST expensive of the "junkyard blocks"

 

I believe the older boss blocks are not made for roller lifters. the stronger block would be the R-302 block from Ford racing performance parts. since you're going with a 347 stoker, you'll be getting new pistons so you can go with whatever material you choose to use also. Coast High Performance makes some good 347 stoker kits, www.coasthigh.com

 

theyre not, but, my friend had it done on his. for his 347. car runs like a scalded dog too !!!

 

i built a 302 to have 400 hp at the wheelsand ran a 12.32 on street tires, no nos. but when i did my dad went out and bought a rear mounted turbo kit on his ls1 and ran a 11.77. so now i must reply by kickin his a$$. i think with the mods that i have done to my motor just swap everything except for cam and fuel injectors.
