Sounds like you really need a bigger injector, but i think 60's? are the next step up and would probably be overkill, hence the higher pressure to fill the gap.
At 435 the 42s were more then enough maybe 40-50 percent duty cycle at full tilt . they are good into the 500s or so .

Yeah man, if you're building an engine go on and get a new set. They're not quite as jinky as timing belts but if it breaks your motor's F'd.

I have been pulling wrenches on v8 engines since 1985 and have yet to see a timing chain break. They stretch, the teeth wear down and jump time, but I have yet to see one break. Not saying a worn timing chain shouldn't be changed.. it should, but maybe if you don't know what you are talking about you should spend more time reading, and less time commenting. That way people who are trying to learn can get accurate info and not bs from someone looking for attention on the internet.
Eat sht plz. You ever hear of a timing belt breaking on another car? What happens then? Broken valves etc. Yes I know, comparing a belt and a chain. But you wouldn't replace your timing set when you were rebuilding an engine? Yes, yes you would as you stated. Why would you change it if they never break? Because you have the motor torn apart anyways and why take a chance on putting the old one back on correct? And what "chance" are we talking about? The chance that it would break. I'm proud for you that you've been wrenching on fords since 1985 by the way. Kudos to you sir. @Mario88 my appogies if you're now confused as to whether or not you should get a new timing set. Yes, yes get a new set while you're rebuilding.

I do enjoy hitting "show ignored content" for a random chuckle. Carry on, carry on.

He never said the chain shouldn't be changed he said hes never seen a CHAIN break. Neither have I honestly So why the hostility ?

You won't see one break. That's part of my point.. his reply is why a lot of people here ignore him. He's got quite the fanclub.. lol

never in 40 years seen one break. Maybe jump a tooth cause the plastic teeth on the gear broke or the chain stretched, never broke though. Takes 2 seconds to see if the chain is stretched or not.
Oh I no . I don't have him on ignore but when I read some of the technical advice given i shake my head . I'm no expert but I do this day in and out so sometimes I know a thing or 2

i know i'm late to the party on this, but for the record, i agreed on the changing because of the STRETCH, not the breakage. the tfs timing set i just replaced was loose (about 3/8 to 1/2" slack) enough to possibly change some valve timing. with this guy making a new build, it makes sense to spend the $100-150 to put a fresh double-roller on it. you'll have to do something really, really wrong to break a halfway-decent timing chain, and if you do, its the least of your worries.

A true testament to your mentality. I will continue to correct wrong advice.. but I choose to keep you on ignore and NOT eat
as advised by you.. about like your mechanical advice..Ok, I'm done. Enough dumb for one day..
So, yall lead the new guys to believe that they all need maximum motorsports full suspension and a motor than can rev to 8k even if they're building a grocery getter.
I appogize about the chain "breaking" that was based on an experience with a car w a belt that broke. All I was getting at was since he's tearing it apart he might as well replace just incase. When's the next time he's gonna have the timing cover off? So yall've never seen any malfunction in the timing chain or gears? Built Ford tough huh?
