The OEM balancers are good for stock rpm levels. If you want to turn that 347 over 6k, I'd rethink the balancer to get one that can handle more rpm. I have one engine planned to push that level, so I'm looking for some kind of SFI option. Hopefully your cam isn't too wild, and you can live with it running under 6k.[/QUOTE
First off. The balancer is not stock. It came with the scat rotating assembly. The engine has been on the Dyno. 7900 to 8500 safe range. Cam is large. 613 on intake. 6** on the exhaust I'm pretty sure. On the Dyno with a fitech it made 506hp N.A.
You will need custom tuning. Different injectors and maf make it mandatory. Even if the injectors are supposedly 'matched' to the maf, its not very close.
You can do the tuning yourself with the sct programmer and the pro racer software package.
edit: I used the damper dudes 28oz balancer, my motor balanced fine with it.
Congratulations on the build. Looks amazing. You have more skills than most of us backyard guys.[/QUOTE
Tha k you and I appreciate the advice
Never seen it done is all. Not hating or doubting.
BTW, there is a special going on this week: x2 bonus cool points per picture posted.
Are you having a custom crank pulley made so as it line up with the explorer pulleys?
Last thing to do is either buy a programmer with custom tunes or have my factory one reburned.
What kind of torque converter are you using? Transmission upgrades? Might need a trans controller too while your at it. And a couple spare transfer cases and driveshafts and...
T case is a np272 so I shouldn't have a issue there. The trans will be stock till it blows. 2800 TCI converter. It's not a mud truck. Rocks trains and hill climbs are the main objective.
