98 300 promax 4 hole butterfly injection

[Varmint]

Is this the same part# as the late 225 and 250 efi's used ? Or is 300 different somehow ? Tks

[vnemous]

250 and 300 are the same part number. 225 was not available with 4 hole hence different part number. JMO

[Varmint]

Ok tks, ya your right most 225 had 2 hole, just wanted to make sure i could use the 300 4 hole on a 225

[vnemous]

you could even use it on a 3 liter 200efi add computers and wa laa you got a 250efi

Tks i already have 250xb and 300 ecu's ,300 pm mid,tuner ,heads and cowling. sending a 98 225efi to machine shop for rebuild and re sleeving anything that dont come into std. Bore specs,

The last of the 2 ecu 225s had the 4 hole intake also.
