Ford did use the shell style initialy. They weigh one third the weight of the dumbell. The first pushrods were solid, and changed to tubular shortly. The T-Bird never recieved solid lifters, but had the machined chambers too. The fuel requirements that the engine needed were as Dave pointed out not kept up around the country. The Ethyl Corporation still was a powerful force back then, and unscrupulous station owners did not want to pay the price, but liked the profit of the fuel. This resulted in doctored gas that gave trouble on high compression engines such as this "new" design which featured a high rod ratio and the resultant spark knock that would occur. The B-9 through the C-6-R was essentially the same, with odd differences. There was as pointed out the Hi-Po heads for a little flavoring. The C3-H,G,J, and CJ have the advantage of the cores for the intake are offset slightly in the middle of the runner compared to the others for flow improvements, along with thicker decks. The lifters were all made by Johnson Tappet Co. There were some called "Skelcast" that were ribbed vertically and had three points of contact with the lifter bore, Engle and Manley sold them among others. The Isky's that Royce has, (me too) are very close to the TRW style with removable top pushrod seat with a different hold down clip (TRW's use a Tru-Arc snap ring like a piston pin has). |
