the weber 500 and edelbrock 500 are the same carbs .
500cfm 4 barrel .
why not just run a 600cfm holley vacuum secondary carb , these will run
ok on a rover v8 and if its tuned will supply more than enough fuel for
it , they are cheaper than the 390cfm which is normally used on a rover
v8 .
see below EDELBROCK PERFORMER carbs
EDL-1404 edelbrock manual choke 500cfm $ 225 .
EDL-1403 edelbrock electric choke 500cfm $280
you can buy them from SUMMIT RACING akron ohio in usa
www.summitracing.com
you can buy direct from these people , they ship to the uk and have
been for last 20yrs , youll have to pay VAT and import tax and customs
clearance fee , but basically the price will more or less end up same
in uk pounds or less as it is in dollars.
you can probably buy the edelbrock/weber 500cfm carb from REAL STEEL
on 01895 440505 , just quote the part numbers from above [whichever
choke type you require ]
to be honest REAL STEEL are much more up on rover v8 carburation using
american holley and edelbrock carbs than anyone else , plus they stock
all the spares for holley carbs, including jets and chrome parts and
allsorts .
other than that buy either a 390cfm or 600cfm vacuum secondary carb
from REAL STEEL .
you can buy an adjustable vacuum spring kit and diaphragm for these so
you can set when the secondaries open , also can get different
accelerator pump discharge parts etc .
youll need a decent fuel pump with these, either holley or carter
electric and adjustable pressure regulator , facet arent really up to
full throttle accelerating with these carbs .
tons of goodies available for holley 4 barrells from summit racing .
