It's considered the same as yelling and can be difficult to read. I don't think it's prohibited, just discouraged and will keep some from even reading your post.

Walbro GSS340 is a 255 LPH pump that is a drop in replacement for the stock 454SS pump , it will provide more than enough flow for what you are doing .

You can usually save a few $$ by ordering the Edelbrock 3581 , it is a re boxed Walbro GSS340 . http://www.summitracing.com/parts/EDL-3581

After you out run that pump there are other options , but will not be a drop in setup.

hell I was looking into an aeromotive but after reviewing the walbro, I can get what I need for a fraction of the price. Thanks again! also I think I might of seen you on forums over at NATC.com? is there a fee to become a member? a lot of good information there.

No problem , I think other than a few people I know I have probably turned more bolts/screws/nuts/etc.... on the 454 SS trucks than most .

The NATC site is a host of knowledge on these trucks, yes , I am a moderator over there , the trucks are truly a dying breed and those who are still stubborn enough to make power through the TBI setup (yours truly included) are few and far between.

You can become a member for free , but any membership donation helps to keep the site alive for others that not only love the 454SS trucks , but the BBC engine in general. There are some very smart and knowledgeable people over there , some of which have "insider only" knowledge ........

Thanks for the interest
