I just want to say thanks for the help, i've come a long way on getting my bargain truck to run like a champ. Im running the stock crushwashers from my old injectors on my 370's and it stumbles and runs really rough at idle. i was wondering where i can get the thin washers from. if i can get them locally, what size amd i looking for. thanks for the help guys, i appreciate it(don't know where i'd be without you guys).

Are you sure you need the thin washers?
Injectors are different in what they require, best to ask the vendor what is best.

everything i have read calls for .020 washers with the 370s. have also heard that one needs at least 181 delivery valves to stop low speed stutter.

thanks, i already put the 191 delivery valves in, helped, but didn't stop it, i'm gonna try the .020 crush washers and see what happens.

you wont fix that stumble completely with those injectors, marine engines have marine pistons which are shaped totally different and run much higher compression. the difference in spray pattern and compression are causing your stumble, which i am guessing is from idle to around to 1100-1200 rpms. stock injectors with schied laser cut dv's flow like crazy. my truck makes more power with stock injectors and schied laser cuts than it did with the 370's and 191's.

that makes sense, i might try to put the stock injectors back in and see what happens. it only takes me about 20 minutes to change out injectors now, not hard at all.
