6.0 Swapped 91 454 SS NEED HELP!

[LQ4Javi]

Hows it going guys, here are some photos of the build. Its almost finished. 6.0, 317 milled heads, full bolt on, cammed, 4l80 , custom harness, e fans. The only issue is my builder is saying the long tubes are hitting the frame? I've had a few guys tell me they should bolt up no problem that they had no issues, my headers are from Schoenfield headers and mounts from Dirty Dingo. Maybe I ordered the wrong headers, They told me they may have to make my drive shaft longer?? Ive asked around and looked online a lot of guys are saying theirs bolted right up with no issues. Any idea whats going on?

What is the part number on your motor mounts? You shouldn't have any of those problems with the correct mounts.

[Chevydillan]

DD2550c is the number fort he correct mounts. 1302ls1 is the number for the 1 3/4 schoenfield headers.

I'm just a noob but sounds to me like whomever installed the motor mounts, maybe installed them backwards or upside down....? As in drivers side on passengers side or top on bottom or vice versa... 1 inch forward instead of 1 inch back. The mounts have an arrow on them I think!

Must be close to the rad also... Most peep say drop in and drive shaft lines right up.

I put my motor in the same location as the old motor with the dirty dingo mounts because they are adjustable front to back. My truck is lowered and the only problem I had was the passenger side header hit the heat shield so I removed shield. It sound like they have the motor to far forward.

Well, what did you find out? What was it?
