To Jim McMullan:

I apologize in advance if I am somewhat confused, but I seem 
to have joined this conversation in mid-stream. Having said that, let me next 
ask (with all due respect), what the HECK do you think you are doing???

Why would you want to mess us a perfectly nice 300F long ram 
car with some kind of kluged-up, cockamamie fuel injection system that 
probably won't work right, and shouldn't be necessary anyway?

I own a 300F myself with original long ram and Carter AFB's, 
and it runs like a freight train on 92 octane pump gas without modifications 
or additives of any kind. Starts, idles, and pulls strong to max revs without 
any problem whatsoever. The secret? When the engine was overhauled a few 
years back, we dropped the compression ratio to 9.2 to 1 (from the stock 10.2 
to 1). Computer simulations indicate that change cost me about 10-12 
horsepower, no more. 

If you absolutely don't want to run your original dual Carter 
AFB's (some people can't seem to get them tuned; I don't know why), then put 
them aside and get yourself a pair of new Edelbrock AFB clones. I know a Hemi 
restorer who swears by them for Hemis, and will use nothing else. 

If you can't bear lowering your compression to 9.2 (and the 
loss of 12 horsepower, which you can make up in a variety of ways, like mild 
porting), and you absolutely insist on having high (10:1 or more) 
compression, then get yourself a simple water injection unit and tap it into 
your manifold in some hidden place where it will feed both banks equally 
(heck, you could probably feed it into a crossover tube from underneath and 
nobody would be the wiser). With a simple, properly set-up water injection 
unit, you could probably go as high as 13 to 1 on pump gas, if you wanted.

But for heaven's sake, don't butcher your crossram. You'll 
probably live to regret it, and if you don't, the next dozen owners after you 
WILL. I guarantee it.

300F'ly,
