For the sake of numbers I’m looking to hit around/close to 900 ish rwhp on my current build below are the list of mods we just sold off the D1SC and upgraded to the F1A 8rib front mount with a 4” pulley and 7.65 crank pulley. Should I stick with the 4” pulley or do I need to go with a 3.90 or 3.80?? Anyone run a similar set up or have a rough idea of what to expect? Everything listed is already here and we are installing now.

correction: I’m running 91 pump gas with the dual nozzle water/meth kit

the injectors are from my previous setup with the D1SC was hoping I wouldn’t have to upgrade just yet I have NO IDEA why I didn’t order the ID1000. Dumb move on my part they cost the same as the 725’s

which clamps should be used, procharger sent the kit that way didn’t think twice about it? T-bolt clamps??

thanks appreciate the heads up, should be a quick fix glad you guys pointed it out early enough.

I should be within the 16-20psi range. Same thing Procharger said when I called them a while ago to double check/inquire about the clamps that came with the 4” front mount kit.

Not saying they won’t hold, but I have seen them let go and tear up a nice hood liner. Just spreading the word!

Might be hard on 91 through the auto. What’s the compression? I’d put the smallest pulley on it possible. Injectors are kinda iffy too.

Nice looking set up! Don’t worry about everyone’s opinions... if the 60 was built right it will live to anything you give it... the sonnax drum is the key to them living..

Nice shop and setup! Don’t see many 383 or procharger setups anymore. Everyone is moving towards turbos it seems. I’m looking forward to the results!

yessir very true, will see how it goes, turbo set-ups definitely cost effective but we threw some stuff together that was cost efficient for me and what was in hand as well. Should have dyno numbers middle of next week I’ll cross my fingers and post the graphs.

A lot of people still hate on the 4l60e but if it’s built right, kept cool it will definitely withstand. RPM has has gotten a few 4l60e into consistent high 8 low 9s. I’m not too worried about it. I’ve added a few precautions such as ATI Flexplate and larger tanny cooler with a deep aluminum pan & proper gauge set up to monitor heat it should do great with the upgraded 1: 2 gear ratios.

tranny is billet and hardened where it needs to be, it’s an RPM build...the junkyard 80e w/ shift kit is on standby but we should be ok haha. I’ll be on the lookout for that stage 25 though lol
