Should I modify my 750dp, or just go bigger?

I like Fisher's response, 100%. chassis Dyno is the way to go. First hand experence. No time for Details just "Cliff Notes" (showing my age) .Dialing in Cars one weekend at Track (all friends). Running Big Block (Built) heavy car. went to 850 cfm DP at Track pulled off friends car running that weekend also. (Built Carb, high dollar, close specs. on total car combo.) 60 ft. times dropped, E.T. dropped BUT Trap speed was UP. re-jetted the 850 ALOT to try to work it in. Best we could do was a few 10ths (yes I know they all add up) . Long story short,put 750 DP back on played with MY 750 all weekend DID NOT MESS WITH ANYTHING ELSE. Just so I had no X-tra variables. After all was said and done I was back to the same jetting and ended up with the only change was I Went to 50cc accelerator pumps .60 ft. times dropped, Slicks spun a tad more off line and dusting all the way through 60 ft. mark. Dropped .5 off total ET. After this LONG build up to qualify this statement. You have to dial every carb. into YOUR total combo at a Track to see what works for you. Try not to touch anything else so you can see if you need another Carb. MERRY CHRISTMAS !
