HSR on carbed 327... worth it?
Right now I'm looking at using the HSR set up on my carbed sbc 327 in my83 bird. Its built, has the double hump heads and is cammed pretty heavy (almost too heavy). I found this in the classified section and was wondering if what I would have to gain from using this setup.

Also what would I need beyond what is in the add to run the HSR.

Re: HSR on carbed 327... worth it?
If your going to salvage most of the efi parts of a tpi 3rd gen you need to decide which metering system you want, mass air or speed density. I'm not going to get into which is better, do a seach on that, theres plenty of info covered on that topic. Also, try to get the parts off a 350 tpi model, they use bigger injectors (22#) which should be enough to hold you over untill you can upgrade, if your in a rush that is.
