Guys will a 351w ecu run a 302HO motor alot better than the standard 302 computer? I am having some weird warm idle issues in drive and only drive almost like the computer doesn't know what to do when under a load and in drive. Just trying to get the truck motor to run optimally ;-)

 

Why don't you try it and see? I ran my 302 on a 351 computer for about 15 minutes and it ran terribly. However, it is not an HO...

 

How much are 351w ECU's

 

probably dirt cheap at a junkyard or on ebay...
