- Great value, quality and fits like a glove!
- I bought these off of their ebay store. Was concerned, but they communicated that they would fit. Boy...they did...like a glove. No notching or even concerns. They fit awesome and look awesome. Quality looks great too. Only took myself and a friend an hour or so to install on my 1984 C10 2WD with my 5.3L LS swap engine.
- Look awesome and fit very well
- These headers look great and fit very well. I'm extremely happy with the quality, and the price is unbeatable. Just to help anyone that may need it, these headers do fit with a 4L80E transmission, the bell housing requires a small amount of trimming.
- Great price
- Used this with a lq9 and 700r4. Had to trim the passenger side trans ear a little and other than that it fit great and only hangs maybe a 1.5" below frame. I also used cpp motor mounts and set the motor as far back as possible. I'm happy with my perchase.
- These are excellent
- 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.
