Took her out for a shakedown ride this morning, 4 pumps of the throttle, fired right up, held at 2500 rpm's for about a minute, idle was a little rough for about another minute, but didn't go dead, then smoothed out at about 1000 rpm, love the throttle response and the torque is awesome, best it has run since I have owned it, many thanks to all you guys for this great forum, I learned a lot from reading everyone else's trial and error, my intake runners are made from 2, 18 inch by 1 1/2 stainless bathroom grab bars, get the exposed screw version, $18.95 each at home depot, I used big block chevy water pump gaskets and a thin coat of black rtv to seal to the heads, took about an hour each runner to get bolt holes located properly, I stuffed a paper towel down the ports in the heads, and set a shallow well socket that fit port snugly down the port and set runner over it to keep it centered over the port, located and drilled the bolt holes, then set one of the stock intakes on the bottom of the flange, lined up the bolt holes, then marked outline of stock intake and cut off excess flange, then grind to final shape, there is only about a 1/8th inch gap between runner and plenum. I used fuel rated hose for the connections , the mandrel bends, pre welded flanges, and smooth inner surface of the stainless tube made this a no brainer, being bolted directly to the heads gives good heat transfer, I am also working on a brace for the plenum, (thanks West ! ), that should give me some heat there also, maybe this will help someone else with their conversion, Single carb forever !!!
