Re: beating this question to death! LT1/4L60E
 

Great thread guys. Sounds like the work involved in this conversion is mind boggling, but I'm sure it's worth it. A reliable engine with 300hp and decent fuel consumption too!!

I've driven the LT1/4L60E police package for many years (when they still made them) and they kick some serious a$$!! They take a licking and keep on tickin' too.

Keep at it guys, don't lose the faith. Please update on your progress. I'll be checking this post often.

Why can't you use the factory radiator?

Yes it will work with red coolant. I have been running that setup for over a year. I do have a electric fan setup with a electrical thermostat for the fan. Wootdog

Re: beating this question to death! LT1/4L60E
 

The reason I didnt use the factory C-10 radiator was because of radiator inlet and outlet sizes. You have to Jerry rig the hoses. There is also a steam pipe setup for the back of the heads. If you use the camaro setup, the hoses fit correctly and one of them actually has another smaller hose coming off of it for the connection to the rear of the engine. Wootdog.

Re: beating this question to death! LT1/4L60E
 

damn...wootdog beat me to it. the c10 radiator is IIRC 1 1/2" while the LT1 has the 1 1/4" or 1" inlet/outlet.

wootdog...did you use the 3 row brackets?

Re: beating this question to death! LT1/4L60E
 

Here is a website where you can get the ac relocation brackets for the lt1's. I used this setup with out notching the frame. www.bowersrodshop.com/info_pulley.htm

Are you sending out your harness to get done?

Re: beating this question to death! LT1/4L60E
 

I sent my harness about a 1 1/2 years ago. It works great!

Re: beating this question to death! LT1/4L60E
 

Where did you send your harness pdr?

Shifty, I could use the part #s for that fuel reg and filter if you still have them handy. Also, im going with a poly tank and external pump for $$$ reasons...any suggestions?

Re: beating this question to death! LT1/4L60E
 

I sent my harness to Lt1 wiring (www.lt1350.com)

Re: beating this question to death! LT1/4L60E
 

What is everyone using for headers with the LT1 swap?

Re: beating this question to death! LT1/4L60E
 

Im running andersons cc11dp headers.

Re: beating this question to death! LT1/4L60E
 

I used Hedman shorties for our trucks. Worked great!

Re: beating this question to death! LT1/4L60E
 

Right on, any idea on a model number? I will be looking in the meantime. Thx!

Re: beating this question to death! LT1/4L60E
 

I am using Street & Performance headers

Re: beating this question to death! LT1/4L60E
 

I am using the Hooker Super Comps.

Re: beating this question to death! LT1/4L60E
 

Dang Fast...now ive got a severe case of engine envy! Makes my LT1 look like a soup sandwich. Do you have a list of all the stuff you got from S&P with part numbers?

Re: beating this question to death! LT1/4L60E
 

I just bought my lt1.

Re: beating this question to death! LT1/4L60E
 

Ok, im running out of funds for the LT1 project so I am going low cost on the harness and PCM work. I just dropped $285 with Jeff from PCMAmerica. Ive heard mixed reviews but he seems like a good fella so im going to give him a try and let you guys know how it works out.

If I can scrape together the funds my next purchase is going to be headers. My only problem is all the ones I see in the catalogs are for the F or Y bodies and only 2 or 3 are listed for Impala/Caprice which is what I have. I would think that any D-port headers would suffice but im having problems find them for under $350. There is no way I can afford ceramic coated versions so im going plain Jane painted headers.

Whats the difference between long/mid/short tube headers? Is one better than the others?

Re: beating this question to death! LT1/4L60E
 

Long tube are the best for performance and short are the best for fit most of the time. You can use any small block headers, you will just have to weld in bungs for the O2 sensors.

Re: beating this question to death! LT1/4L60E
 

Only one word of wisdom from me. It is always best whendoing a project like that to take before and after pictures, and any other info you have and send it to JoeFrus@americanthunderbike.org May not make the job go well, but it could help me when I do the swap myself. :D

Re: beating this question to death! LT1/4L60E
 

I just realized this thread has been going on since 2003.

Re: beating this question to death! LT1/4L60E
 

How did most of your guys resolved the AC Hitting the frame problem?

Re: beating this question to death! LT1/4L60E
 

Well I think there are 3 options...relocate the comp with the corvette setup, delete the A/C and run the delete pulley OR notch the frame for the belt. Since I live in the south and cant afford the vette setup im going to be notching.

Re: beating this question to death! LT1/4L60E
 

When running the AC delete does the frame still has too be nontch? How much has to be notch? any body has pics?
