Barrie,
Like many things in life you will find people tend to Be either A or B.
Everyone has a preference, they can be based on fact, feeling, familiarity
etc..
I have had both, however the Holley I had was a mechanical 650DP (aka track
ubber hotrod carb), the edelbrock was the classic 625cfm Vacuum secondary
carb they copied from Weber. The Holley had more brute power and really had
that hot-rod feel and power. But it did not idle or cruise as well. The
edelbrock idled smooth as silk, cruised very well, improved mpg by over
2mpg, BUT did not have the punch of the Holley. The Holley literally made
the engine pop going WOT, BOOM your gone, the Edelbrock came on smoother and
did not have the power at top end.
Holley; widely popular specially in hotrod sectors, in terms of aftermarket
carb mods, Holley probably has more options (main bodies, bowls, etc.)
Requires draining bowls to change jets.
Edelbrock: popular with street rods and cars that see allot of cruising or
more daily usage. Less aftermarket options, but changing metering rods can
be done in car without draining carb bowls.
If you main tuner/mechanic is a Holley guy, that does have a benefit, always
good to use what your primary wrench uses and likes ;-)

Subject: [Mgb-v8] Holley vs Edelbrock
I have had an Edelbrock (Weber) 1404 carb on my 3.5L Rover V8 motor
since day one. I have never got the engine running "sweetly"
although I do have a mild cam. I have found a mechanic who
understands these things and is heavy into track, hot rod and such
type cars. He did a few things to my motor - found a few faults like
timing was off, carb was leaking air a bit. Now it runs much better
but he is saying I should replace my carb with a Holley - night and
day he maintains. He, and his high tech man (computers,chips,
whizbangs and that sort of new stuff) say no one runs Edelbrocks in
the stock/hot rod/track cars - no one! Now RPi in UK extol the
virtues of the Edelbrock which sells in UK as a Weber, but then they
sell them - not Holleys. Has anyone had both? and what difference
did you find? Please accept my thanks in advance for any replies
Regards,
Barrie Robinson
