Re: S10 Swap how to
 

BigFrz, I don't think Chris (skymangs) is suggesting you buy two core supports. In the post you refer, #6, he had two projects going and to get a picture sequence, he used the Chevy support as a start and the GMC support to show the complete. Now why your radiator don't fit in your support, I don't have a clue but I feel sure it has nothing to do with you needing a second support. Clay

Re: S10 Swap how to
 

I used a 19x22 radiator from Summit, fit perfect. You need to do some trimming on the core support to get it in there.

I've got some pics of how I had to trim mine for a 19x22 radiator in by build, post 75:

Re: S10 Swap how to
 

I have a question as to why everyone has trouble getting the steering lined up. My uncle has a 1988 s10 with a sb 350. The steering shaft goes through the headers no heim joint. What is the difference with the 47-54 s10 swap?
Thanks

Re: S10 Swap how to
 

the motor moves back on the frame 4-5 inches with the old body. s10 swap mounts move the motor about 3.5-4 inches forward. that is 7.5-9 inches difference

Re: S10 Swap how to
 

It also depends upon which headers you are using, and where exactly the steering column exits the cab. My GMC cab is slightly different from the Chevy cab, and as I recall, some people with Chevys move the column in order to center it between gauges.

Re: S10 Swap how to
 

Thanks guys. Good to know. (and knowing is half the battle)

Will this mounts fit a 1987 s10 chassis using a 1957 cab and long bed, also Do you sale this mounts?

Re: S10 Swap how to
 

57 cab would need different mounts this is for the 47-54 advanced design trucks

Do you know if theirs a thread for help with the 1957 trucks to s10 chassis swaps?

Re: S10 Swap how to
 

For the radiator, is it 19 wide or 19 tall?
Thanks for all the help

Re: S10 Swap how to
 

19" wide and make sure the bottom connection comes straight out, 90 degrees, some come out 22 degrees. Or a least choose connections based on your water pump configuration. Mine also did not come without a drain port. Cheaper is not always better.

Re: S10 Swap how to
 

Thanks, where did you get yours. I am having trouble finding a 19 wide radiator.

Re: S10 Swap how to
 

Actually, 19 in. tall by 22 in. wide. An no, the neck does not need to be 90°, at least it was not for mine. I found it challanging to find a 19x22 in. radiator with a straight neck in a decent price range with a AT cooler.

My radiator came from Summit, P/N SUM-381324. More on it in my build Post 75:

http://67-72chevytrucks.com/vboard/s...=664837&page=3

You are right, I stand corrected. 22" wide X 19" tall. I got my from speedway. I got a cheap one, would have been better to pay more, if running Automatic, get the integrated AT cooler, drain, straight outlet is better.

Re: S10 Swap how to
 

Ok I have a series of questions regarding my brake setup and I am hoping someone can help. I am doing a hydroboost from an astro and I have the stock steering box from the s10. I have a 5.3 Vortec with the PS pump and I think that the PS cooler is from a 5.3 as well. I am having trouble wrapping my head around how it all has to be connected. I have searched the internet and have found many diagrams that show how to hook it all up. The main question is.... how do I know which is high pressure vs. low pressure and the direction of the flow for all of the components? It is my understanding that the low pressure is usually just regular clamped hosing and the high pressure has the fittings, but I still do not know which direction everything flows. Any help you can provide would be greatly appreciated.

Re: S10 Swap how to
 

Thanks Reaper71!! That's exactly the info I needed.

Re: S10 Swap how to
 

I have a question concerning wheel size and back spacing. I know most people run 2 inch spacers up front and swap to a 4X4 rearend as I did on "FRED". On my new build I am really considering going with Detroit steel or Coys new c33 smoothies, if I have figured/measured right I can have 4.5 backspacing on a 9 or 10 inch wide wheel (for a deep outside lip) and not run any spacers or swap out my rearend. Thanks for your help fellers.

Re: S10 Swap how to
 

I didnt run spacers on my GMC, and dont plan to on the 49. I didnt even switch to a 4x4 rear on either. backspacing is the key, like you said. I used 0 offset fronts (7" wide 4" backspace) and -12 offset rears (8" wide 4" backspace) and they looked just right.

http://67-72chevytrucks.com/vboard/p...ictureid=22047

if you call mobsteel spend some time talking to them about exactly what you want. and if you have seen an AD with mobsteels tell them, they keep excellent records of who they sold to and for what application. I ordered some for my friend and mentioned the truck with mobsteels he was trying to emulate, they knew the widths and backspacing and even the front and rear axle widths of the truck. then he said the caps wouldnt fit without modfying them and sent a fedex call tag to pick up the caps, modified them, and sent them back with the wheels. I havent had a better experience with a company before that or since.

Re: S10 Swap how to
 

I don't believe Chris is back yet answering questions but does any one know the Part #'s on the Fuel pump, rotary vane - Oreillys - $80 there is 3 different ones they sell thanks

Re: S10 Swap how to
 

Which are the three pumps you're looking at? Internal, external, why not go to the manufacturer and look at the pump curve information and see which one works best for you.

Re: S10 Swap how to
 

Great information!. I am new to this thread and ready to start a 1948 GMC truck chassis swap. Will a 1994 S10 2 wheel drive, 4 door Blazer with 117" wheelbase work as well as the S10 Truck chassis?

Re: S10 Swap how to
 

Bisett, from what I have read it is not the best frame to use for a pickup swap since it rises up in the bed area. There are a few threads that address this, as well as a bunch of others that have a lot of info. Here is a partial list of threads I'm subscribed to. Sorry to those who are not listed, but I subscribe to about 30 and don't want to overwhelm this thread. These are the most recent with posts...

For the 117" wheelbase, most have gone with the regular cab longbed when using an S10 chassis.

tlorber - thanks for the quick response, information and other threads - great stuff!

Re: S10 Swap how to
 

Here is a '96 4x4 Blazer to add to the list.

Re: S10 Swap how to
 

Yes msaintg has a great thread for a 4x4 Blazer frame swap. They do not rise up in the bed area. If you look at the pics in the thread he ends up with a low riding stance and only gives up about an inch of bed depth.

I have a 1951 3100 and swapped it onto a 2001 Blazer 4x4 frame. Like msaintg I took off all the front wheel drive stuff and am just using 2 wheel drive. I had to shorten the frame 9" to get to 116". Most of what you see for S10 pickup swaps will apply.

Re: S10 Swap how to
 

Hope you're doing well Chris, and to have a speedy recovery. Just to keep this thread updated with more info, anyone using any other ideas for a throttle pedal? s10 assembly was destroyed upon removing from the donor car I had and I may need to opt to another option.

This has been a fun project for me and cannot thank Chris enough for his efforts in gathering his knowledge to the community. Thanks bud!

Re: S10 Swap how to
 

For those of you that have put an LS motor (LM7 in my case) onto the S10 chassis, do you have spec for which steering hose you used for the high pressure side? Here is a picture of the fittings I need to meet up with.

Thanks for any input.

Re: S10 Swap how to
 

I am here and able your to answer your questions. I'm back by not 100%. Unfortunately I don't know the answer to your question. It is not like I can run to my shop and check now is it.

Re: S10 Swap how to
 

you could however, the motor won't be far enough back for you to run an electric fan

Re: S10 Swap how to
 

I sure hope that was supposed to be funny because i chuckled a little bit...:lol:

Welcome back and keep getting better!

Re: S10 Swap how to
 

I just took my hose ends into O'Reillys they made me a hose to my measurements

Re: S10 Swap how to
 

If I understand it right you are asking about using the S10 V8 conversion mounts. If it is, that is what I did. You see how I went about it in my build thread, Post 24:

Re: S10 Swap how to
 

you have two trim your current core support to fit the 19 x 22 radiator. You will also need to trim the core support below the side nuts.

Re: S10 Swap how to
 

It was, I burned my shop to the ground. Thank you. I hope to have my shop up and running by next all truck nats.
