Will my RSI fuel system handle my 427 YSI ?
My old build was 402 YSI, AFR 245 heads,1014 RWHP with meth. I am wondering if the same YSI set up..same 2.75 pulley and meth on my new LSX 427, MAST 305 heads, will require more fuel? Can I add a 3rd pump to the RSI system...IDK 1000 injectors...bigger cam also...
Do u think the new combo will produce much more HP ?
Also what throttlebody is good for it?

It should.. I ran the RSI setup with twin 255's and Meth injection well over 1000hp for about 8 years. May want to swap the pumps to 340's for some head room, same physical size. Putting 450's in their place will not be a drop in. You will have to get creative.
