yeah i can feel that it needs to breathe more with a bigger throttle body and intake.

did you replace the TB with a larger one? the stroker motors need A LOT more air than the 4.0

the 12 CW shouldnt effect highway performance, the crank is already rotating at a high velocity, you just need to make it go a little faster. making things go faster after they're already moving isnt hard - its getting them going or trying to stop them that is the issue

Update:

i have unfortunately ran out of money to spend on this project for the time being and things are progressing a lot slower than i had originally hoped for - it looks to be that summer is the new hopeful deadline. There have been a few things that have come together that have set me back a little bit. i had an opportunity to buy a new slimline subwoofer at discount for a different audio based project and im now out $130 with that. Im also in the process of moving to Lexington (Kentucky) and my finances will be a bit screwed up till i can get settled into a job.

in other news, i have decided that I'm going to focus on a just the stroker right now and getting the long block finished. I do see myself later down the road working with the head but that is not in the books for right now unfortunately. maybe i'll nab a Avenger and have something ridiculous.

that is all, sorry

apparently someone makes a custom crank to go 5.0, which is the biggest you can do on the motor. i think that requires like a .080 bore too. who knows.

Hesco does make a 5.0L motor, might be worth sending an email to them aboot it

Hey can i recommend going 4.6L stroker first. Then once it wears out all you gotta do is get it bored out again and bigger pistons for a 4.7L. Thats my plan and why i went 4.6L.

too bad nobody makes a forged crankshaft for the 4.0L the hesco hardchromed is a good idea for friction, but doesnt do to much for strength like forging does
