Are you using the 1 3/4 or 1 7/8?

Re: Speed Engineering LS Swap Headers Findings

My initial impression is that these are a great buy.

Re: Speed Engineering LS Swap Headers Findings

bill1969camaro,

It's kind of a bad camera angle, but in the fourth picture I posted you can kind of get an idea of how low they hang. It's been a while since I've looked at it, but I don't believe it hangs down much more than 1/2-3/4" below the frame, if that. Of course I have the 1 3/4 headers, the 1 7/8 may be a bit more.

Re: Speed Engineering LS Swap Headers Findings

I bought the shorties - http://www.speed-engineering.com/fea...c10-truck.html .

So nobody runs into the same thing I did, stock plug wires will NOT fit, 3 of them on the driver side are pressed up against the headers. I was going to order the Accell 9000 series ceramic 135degree wires but some reports indicate they are not long enough and pull off the coils. So I ordered the Taylor TAY-76046 from Summit. Will see at end of week if they fit.

the notes for the long tubes indicate they are tight but vendor doesn't have the same warning for the shorties.

I have them on my 63 with a t56 and ECE mounts. They fit great. Nice quality for the price.

Re: Speed Engineering LS Swap Headers Findings

I instaled the 5.3 in my 65 over the weekend and put the 1 7/8 long tube headers on today, they fit fine. I'm not sure if the following will be of any help to anyone but I'll add it anyway. I used the original V8 stands in the rear position with ICT Billet mounts from eBay. The mounts are in the second position from the rear of the adapters. This allowed my trans mount to match my crossmember location because I didn't want to mess with the driveshaft length. I had the driveshaft shortened in 2001 when I changed to a 700R4. The only problem this has created that I've found so far is the rear coil on the passenger side hits the firewall, not the end of the world. The drivers side has a ton of room but the primary for cylinder #4 is about 1/4" from the frame. The ground clearance is higher than when I had long tubes on the ZZ4 I pulled to the 5.3.

Re: Speed Engineering LS Swap Headers Findings

I'll have to take a side view next week when I put my engine back in, the cam retention plate was creating oil pressure issues. I hope to pick it up from the machine shop Monday.

This kind of gives an idea of how they hand down, the trans X member is in the foreground.

Re: Speed Engineering LS Swap Headers Findings

Those collectors look like they're pointed directly at the trans crossmember. Did you have any problems routing the exhaust?

No, there is about 8-10" on the driver side and a little less on the passenger side, the muffler shop put a couple on small bends in and was able to tie into my existing pipes. I'll post a picture in the next few days.
