350 to 454 swap, 73 c30 questions

[stevo_p]

New here but want to say thanks for all the other information I've already found that's been super helpful. Just finshed rebuilding and stand breaking in a 454 that came out of a 82 k30 and getting ready to swap it for the 350 I've got in my 73 c30. Just making sure I've checked all the boxes before I go to pull this so it's not out of commision for too long. Main things I'm concerned about are new motor mounts, power steering pump mounting bracket, and fuel pump.
1. Seems that I should use the 454 style frame-side mounts, but the block-side mounts off the 350 will work?
2. I've already got the 454 alternator mounting brackets and alternator mounted up. But for the power steering pump I've found it seems I need a 454 style lower mounting bracket, the one currently on the 350 won't work?
3. The 350 pump on there currently has no fuel return line, but the one I've been using on the 454 on the stand has a return line. I can't find one that says it's made for the 454 without the return line. Don't feel like plumbing a new line if I don't need, can I use the 350 pump on the 454?
Any help and clarificaiton would be great, thanks!

The p/s pump brackets are different.

I’m 99% sure the fuel pumps are different, the arm is different if memory serves correctly.

Delphi MF 0068 is 2 line.

Yes they will. The correct engine mounts for the BB are the same except they are stamped out of steel one gauge thicker than the SB. Yes different soft engine mounts, they bolt into different holes in the cross member. The holes are there. Run a tap through the threaded holes to clear the rust since they haven't been used.

Sweet, thanks, makes me feel more confident. Anyone know the part number or got a link for that power steering pump bracket by chance? And if it matters I've got the long water pump on there
