Those headers look real nice and fit well with the 5.3.

Are these the motor mount sliders that you used?

Yep, that's the ones.

Thank you. Which motor mounts or brackets did you use?

[65Gregg]

I used the stock 65 V8 stands.

Your exhaust looks great. Thanks for the posts.

Just dropped a 5.3L/4L60E combo into the '65 C10 using the 1-7/8" headers from Speed Engineering yesterday. They fit exceptionally well. The only place where they're tight is to the starter kickout on the transmission bellhousing. Otherwise, there is plenty of clearance to the engine stands, frame, etc.

Looks pretty nice. Which motor mounts did you go with?

Thanks. We ordered Speed Engineering's mount plates along with the headers. The mounts are stock replacements for a '65 V8, and the stands are the stock '65 230 I-6 pieces.

Racecougar have you tried mounting your passenger side coils yet? Mine hit the firewall, I swapped mine out for some off of a '11 truck, they are shaped differently.

[racecougar]

I haven't yet, but I'm certain that the passenger side coils/bracket would contact the firewall with where we've positioned the engine (it's set back pretty far). I don't plan to run the coils up on the valvecovers though.

anybody tried these with Tejas mounts??

Wondering the same thing.

I'm going to get a set for my install in December (using the Tejas motor and transmission mount). I've emailed Speed and got a response very quickly (some would say... "speedy").

Not sure yet on whether to go with the shorty headers or the long headers. Shorty has v-band and I am installing in a C10 longbed... and maybe could repurpose them for a turbo install later. However, long headers might be better overall/top end, are closer to equal length, look fancy... and I may never go turbo and should just forget about pipe dreams.

Decisions, decisions.

[racecougar]

I'd choose the "best of both worlds" route and weld V-bands onto the longtubes.

[PhilistineAu]

Mine arrived today. Unfortunately the box was beaten up and one of the collectors has a dent in it. Not irreparable but not necessarily something I wanted to do either.

They need to improve their packing it seems.

[racecougar]

Been there.

[PhilistineAu]

Methinks it is time for them to invest in some polystyrene donuts. I got off lucky compared to your box. That's a beating.


Update: I heard back from them and they told me to fix it with a crescent wrench. Not a big deal, but perhaps an offer of free shipping or discounted v-band flanges would have been nice. For now, I would avoid ordering from them until they get their packaging situation fixed OR unless you are willing to pay for headers that will probably have some sort of damage when they arrive.

Those longtubes look great! Im stuck between the mid length and the longtube for my ls swap in my 71. When you get time can you post a pic of the longtube where it hangs below the frame, but a little farther away from the truck. Trying to get an idea what they look like from a distance.

Absolutely. My engine won’t go in for at least another month though, but I will get you the photo. When I talked to them they assured me the long tube headers should clear the 6L90e, but using the Tejas Steelworks mounts which lift the engine may create some spacing issues.

Here’s my fitment with Dropmember version 7, super happy with these:

I ordered a set of the long tube headers and when they arrive i will post some pics. 65 c10 with 5.3 using speed engineering motor mounts.

I posted pics of that same setup above.

Just curious which style you went with, I have a 66 C10 and plan to bag it in the future. It'll be lowered for now, but don't want any fitment issues down the road.

Nice looking setup by the way!

They are the C10 specific (same part number as Chevelle) LS swap long tubes. The reason they work so well is due to the dropmember raising the engine. Stock engine location, I think the collectors will hang down 1.5” or so, too much for a heavily lowered or bagged truck, in my opinion.
