Been awhile since I've been on this board but, hear I am. I pulled the 350 olds and t350 trans and got them both rebuilt now with them back in place I'm going to run some straight back headers. We'll I'm running into a problem with them bumping up against the support brace and thoughts or help on trying to get these to fit nicely? Manga flow headers.

Hard to understand where the issue is. The passengers side is on but the drivers side won't fit? You might have to raise the engine to get it to bolt up. It's not uncommon to have to massage a tube or 2 with a BFH. What vehicle are the headers for? I don't see MagnaFlow having headers for a 350 Olds.

Sorry about the confusion I haven't bolted them on yet just have them lined up at least on the passenger side.Your probably right with massaging them but I haven't gone that far yet. The headers are for a 77 lemans that was built for high altitude so it has a 350 oldsmobile in it. My bad the Flowmasters not magnaflows.

Gotcha. I don't think Flowmaster, or really anyone makes headers for these colonnades though. I had great luck with Hedman headers from a 2nd gen bird fitting like a glove, but your 350 Olds is a different animal. Hopefully you can get them bolted up with minimal massaging. Was it a stock style rebuild on the engine?
