Using s10 SBC Longtubes to make LS1 Long tubes...

2xr95s10 · 10-15-2009, 03:16 PM

Just had an idea this the other day and wanted to get some more feed back on it....

Say you buy a set of SBC S10 Long tubes, which are around 200 used or 350ish new and bought a set of ls1 flanges and a bit of primary piping for around 100ish (just a rough guess) and modifidy the top say 6-8 inches max of the two inner primaries to line up with the ls1 flange. Making a set of LS1 s10 longtubes for around 3-400 bucks compared to the over a grand the normal s10 LT's cost....

Anyone think this is possible? Any feedback is appreciated....

Only thing i can think of is if the heads on both motors are in the same spot to line up the flanges?

Saw this question on tech, my longtubes for my S-10 SBC racetruck were closer to $600.00, 1 3/4 primaries, and were in 3-4 pieces each side. To begin with, the headers your going to start working with have the center cylinder primaries nearly touching, or connected. The LS are completely seperate from one another spaced out across the heads. It's only my opinion but I start with what I need, BRP sells LS swap headers with good feedback and competetive pricing with several options in size and finish. Just my 2 cents!

Also the heads on a SBC are at a different angle than that of an LSx engine. If it's something you want to tackle just to say " hey I did it" cool, and you have all the tools then go for it. Good luck, let us know if you decide to go through with it.

well i dont think the angle would be too big of a deal since i would be welding on a new flange so i could just angle cut the primaries to the right angles. As far as the two inner primaries those would be re-worked to widen them out to line up with the flange.

Anyone else have any opinions?

2xr95s10 · 10-15-2009, 04:22 PM

Also on the BRP website is says for 82-93 s10's. Will they work on my 95?

tiresmokinV8 · 10-15-2009, 04:33 PM

Yea people have used the BRP on trucks as new as 03. GM didnt change much frame/component wise through the years so you'll be fine.

2xr95s10 · 10-15-2009, 04:38 PM

Thats what i thought. ANyone know the price for the 1 3/4 primary LT's non coated? the coated are 709 and that is way out of my range, Anyone have a price on the non coated ones?

Those are only 530 for the coated, never realized they were that price. I tried callin for a price on non coated but they are at the lsx shootout and closed til the 20th. Anyone have a price on non coated?

Barry · 10-15-2009, 05:34 PM

Ive considered buying or borrowing a set of un coated Pacesetter Long tubes for the 03-05' chevy silverado. I dont think there would be much modification but I dont want to invest in something that's not gonna work at all either...We really need a Long tube in frame option here people! I'll probably end up modifying a set of Hedman midlength's. Now where did I put that sawsall?

yz85608 · 10-15-2009, 09:34 PM

the longtubes probably cost a bit more the 530, since you have the option of having mid's and lt's

2xr95s10 · 10-15-2009, 10:53 PM

ah ya i didnt even think about the ebay add mentioning both midlengths and long tubes. the 530 is what the mids cost on BRP's website so thats probably what that price is...

I dont even care if all the tubes are inside the frame rails, i'll be running open headers so that doesnt bother me a bit, its a drag truck and i'm just looking for a long tube option on the cheap... that could even be a fenderwell header. I've thought about both trying to make my own fenderwell headers, or tryin to modify the SBC LT's and figured it would be easier to modify the SBC ones unless anyone else has any ideas....

anyone think i would have any other problems or interferences with modifying the SBC headers other than the obvious work i'd have to do on the flanges and the upper part of the primaries? do you think the clearence around the steering and frame woud be the same since i'm only modifying the top 6-8 inches or so of the primaries?

hedman is building header kits lsx motors in s-series now...

Come on scott where have you been??? I think everyone know about these by now

Same stuff brp hotrods sells. I think hedman makes the headers that brp desinged and brp makes the mounts and crossmembers for headman. Both sell these in kits.

Iroc-10 · 10-22-2009, 11:45 AM

I read on Malibu forums that a guy used ford 351M headers, cut off the flange and welded on the LS flange. He said the tubes almost line up perfect. Of course, there are other clearance issues with our trucks, just an idea I thought I would pass along.

ssDimer · 10-22-2009, 02:19 PM

I've seen a guy use big block headers and cut the flanges off and they line up real good with ls heads but have fun finding bbc headers for s10. Joe you know you can call me if you need help or have questions right?

2xr95s10 · 10-28-2009, 01:32 AM

Ya for sure Todd, Haven't made any progress at all on the truck lately. I really need to start buying stuff for it here soon. Just bought a new DD Sierra from randy that needs a little work yet but after that is done money is getting dropped into the s10. Might end up with stock 98 f-body manifolds with the collectors relocated temporarily depending on money situations this winter, I will have it done by may or so for sure. Not missing another season of racing with no car lol
