I just bought an ERA with an aluminium 427 Shelby built/dyno'd engine. It don't have all the specs but it was built for the street with 10.5:1 compression and a hydraulic cam. It was dyno'd at 498HP. It has shelby AL MR heads and dual plane intake. It came with a Holley 3310 780 CFM vaccum secondary carb but the previous owner had trouble with it and had a mechanic replace it with a Edelbrock 750 CFM performer carb.

I woud like to put the 3310 back (along with its turkey pan). I was looking at going to the proform main body to get a little better throttle response and tweak/tune it while I am at it. I am looking for anyone who has a 3310 on their 427s and what their set up is. Also if you have done the Proform main body upgrade. If you could either post your settings or PM me I would appreciate it.

Lastly would I be better off dumping the 3310 and going to a demon or other mechanical secondary carb? Seems that a mechanical carb might work better but I am not sure.

Thanks
