When You install the dp how much do u need to beat out of your fire wall?
will it rattle really bad afterwards or should i throw in a body lift and what size lol.
any help is appericated

how big of a dp you putting in

[fordpwrstroke7]

Port it with a port a power. You will be able to hear the rattle and then you'll have to go back and do it the right way, after the fact. Trust me, do it right the first time and port it. If you have the tools, it would only take one minute to do it.

3 inch
what you mean by port it?
long day of work so im beat

[fordpwrstroke7]

You might not need to do anything if it's a 3" on the OBS. Porting is basically bending the firewall back towards the cab so that there's a little extra clearance for the dp. It only takes a little bit to do it. The port a power if placed between the motor and the firewall and, through hydraulics, pushes the firewall back to create that clearance.

A guy almost beat holes in his firewall I heard cause he managed to fit a 5" in there. Never got to see it though.

[farmboypowerstroke]

3 inch will fit no problem

all I did was wedge a 2x4 in between the block and firewall and pried at it a couple times and that bent it out enough that it just slid right in, no rattle or anything

i used a big spud bar. it only needs to go back maybe a half inch at the most. and its not hard at all to push in.

but what rattle are you all talkin about? i never got a rattle...
