428 street Hi welcome to the ERA club Get some books on the FE motor and read. MAKE NOTES. ERA has an enigine company they have been using for years, I have heard of no problems. At lease let them do the short block. You have Gessford M , Kraft M, and others who build these motors. ASK questions, alot then decide what you are looking for with this motor. Streetably and Quiet, Loud and *****y, or Strong and Durable. Kit car show is coming up in May, Go to it and get a good idea about what you motor will sound like. Get prices or rough cost on parts. Check with FE-Ford on Ebay, there are parts for sale on there. Jegs, Summit, and PAW all have parts for an FE. Check pricing on all your parts, you can save 20-30% by shopping around. Power and speed is all about who much money you want to put into the car. I have a 360 hp motor in my ERA, runs 12.50s all day in the 1/4 mile. I do very well in autocross and roadracing with a stock motor. It idles at 700 rpm smooth. I am building another Shelby motor that is bigger 489, 11.0-1comp 600" lift cam, 6.7 rods, 4.25 crank, I am looking for 600 tork and 550 hp when done. You have to remember that a Cobra wieghts 2500 lbs with motor give or take 200 lbs. Much more the 500 hp 550tork THESE car are hand fulls. Talk to Pete, Doug, and Jim H at ERA, they give GOOD ADVICE
