They fit perfect in my 88 Ls brougham caprice classic with no problems . Didn’t have to modify or adjust anything . Bolted up fine and fit in there perfect & yes it’s they’re on my LS motor ( did a LS swap )
Fit my 72 c10 6.0 LS swap very well. These are easily the best bang for your buck headers.
I bought these for a 1970 c10 with a gen 3 5.3 ls and 4l60e trans swap. They fit great. Installation was easy, the don't come in contact with the frame or trans or anything and aren't overly priced either.
I purchased these in person in the shop today, I was a bit nervous about their fit because so many big name places claim theirs will fit 73-87 C10s but many do not fit at all. These are a perfect fit and require zero cutting of the frame or crossmember. The only modification these needed to work on my truck is a simple one. Cut the passenger side transmission ear off with a grinder. To be fair this is likely because I'm using an early style 4L80E. I couldnt be happier with this product. Well done, Speed Engineering. Just so we're clear I'm in no way paid to leave this review and I do not work for/with Speed Engineering. I'm just a happy customer who is very glad to pass along the good news to fellow 73-87 C10 owners. Now theres more options than just Trail Blazer SS headers, which can be very expensive.
