.025 tips on KDL injectors ,093 lines, 450 head for the pump with some special work done like locking the advance. Needs to be done by someone who knows those pumps. I made other small gains by putting bigger feed lines from the tank to the pump and advancing the timing. I think I ended up around 20 deg. advanced. I got injectors, lines and the pump from Columbus 17 years ago but had the pump redone by a good friend who knows them well. Have fun !

I have an awesome set up for my 4320. Have 5x20 injectors and 450 roosa with .093 lines puts out 440cc. I run a electric pusher pump with 3/8'' lines. It runs amazing. The setup isn't cheap but if you want to give the red 66 fits this will do it. May all be for sale as I may be moving up to bigger things.

A 450 roosa will not run with a good m100 on a IH. But why don't you call a good pump shop and ask what they would recommend. That's probably where you would buy them anyways.

I agree It's hard to beat a 66 that has had pump work or if it has a truck motor.

Like mist John Deere’s don’t have 466’s in them to, come on let’s be realistic if you have a competitive Deere it’s got at least a 466 in it. The whole truck motor thing is a joke. If everyone would of just taken the 466 crank and pistons out and put them in the 414/436 blocks then what would everyone cry about on a binder

Not crying just a fact. Just like going up against any 466 with the big IH pump or JD with an A pump.. A 404 with the right parts can be a lot of fun and it won't break your bank account.
