I am interested in selling my 350 w/144 blower and doing an LS1 conversion in my 56. I'm brand new to the LS1.

I've read a little about needing to either purchase a new computer, or harness; or have it programmed to turn off things and turn on things, etc.

Would purchase of HP Tuners, and other components, along with some research, provide me the capability to save purchase of a new computer or harness?

If so, can anyone direct me to information on what I shoudl plan on programming? Maybe a 'How to'.

Also, as that I have not purchased an engine yet, any feedback on what I should look for, or steer clear of? Particular add-ons I should consider?

My current 350 has a built 700R4 behind it. I'm told I should sell that too, and put in the auto that comes with the LS1.

My goal: have a very streetable, decent performing, good looking engine in my 56 Kruiser.

Any suggestions and feedback appreciated.

what you need is a LS1(possibly LS6), preferralby a 01 or 02 due to small differences but any other year would work fine. get HP tuners to edit the computer or get someone to tune it for you. make sure you do all the test on the engine b4 u buy it if possible, although these engines are really strong. the 4L60E is a good trans for near stock power levels from an LS1, not the most reliable after that. http://ls1tech.com/forums/forumdisplay.php?f=28 that is the conversion section for LS1Tech, they probably can tell you exactly what to look for in a engine.

So, is there an Auto/Overdrive transmission that is more reliable that I should consider? Is there conversions/build capabilitys that would strengthen the 4L60E? While I don't plan to take the care to the dragstrip, or race it regularly, that is in my blood from the past, and I know I will be on it some.

Oh, and thanks for that link. I had found that site but had not yet gotten to that specific forum.

yes... the 4l80e since you are going to be fabbing up stuff to get the ls1 in there , you might as well get the best.

the 4l80e is built from alot of the same parts that the th400 is made of, basically think, strong as a th400, electronically shifted, and has an overdrive...:cool:
