I am starting to gather some information for my LS7 swap into my 1970 chevelle, and I have been trying to find some information on a good standalone system, Or if you think it would be better if I got a factory PCM and modified it for my application. Any suggestions or information would be great. I was debating between here or the tuning section, if I'm in the wrong place please let me know you guys are all very knowledgeable and I don't want to step on any toes here.

For some info on the car I am going to be building pretty much everything from scratch, and this is going to be my first non-carbed build. I plan on going with a World products warhawk 427 ci block with a weisco forged rotating assembly running a 9:1 CR (still deciding on heads) and a decent cam with a 114 lsa. My power goal will be around 750 to the wheels at low boost for street driving. This will be bolting into a fully independent suspension and aftermarket frame from the roadster shop and be backed by a Built 4l65/70E.

 

A 4L65/70E will die quickly behind that motor. Regardless of how "built".

 

I just chose that because I found one cheap, but its not set in stone as of yet. if you have a better suggestion I'm all ears, I want to stick with an automatic though.

 

If you want an over drive, go with a 4L80E.

 

Thanks for the advice.

In the line of standalone systems I have been looking at the FAST XFI system. does anyone have any experience with that system?
