Carb Choice - Help wanted

[mikey]

Awaiting shipment of my Mowtown 415 and need to choose a carb. Many are advising of the Edelbrock over here, but I am a great lover of the Holley.

I am interested in the Barry Grant Speed Demon - anybody got any experience of this unit - is it better than the standard Holley.

Also I had assumed with the 415 cu in block and Edelbrock Victor Junior Heads/Performer RPM Hydraulic Roller cam I would have needed around an 800cfm carb - not so according to the Barry Grant Web site. Any opinion on this as they advise that a 750cfm should suffice. I would prefer higher intake flow if delivery is sufficient.

The other thing is they only do mechanical secondaries without the electri choke and I believe the vac secondaries set up is better for the road due to wash down etc - am I right in thinking this. I dont want to run a choke set up so does anybody know if its an easy job or not to simply take the electric choke off the unit.

I always find your help invaluable and I would be grateful if you could once again help me with my queries.

Hope you are all well out there - hope to come over in the near future to meet up with some of you.
Mike.
