I was looking back at some old files and found this article from “RACECAR” from May 1979″.
This link is to the whole article describing Formula Fords built from the mid-60’s to 1979.
Charting the Fords-FF general info
What is most interesting to me is the Elden Formula Ford part of the article. The following link is the only place I have seen the where the 4 models of the PH10 are described relative to the radiator placements:
1972-73 PH10 with single front radiator similar to the PH8
1973 PH10A is a PH10 with the “Falconer” body with twin front radiators.
1974 PH10B is a twin side radiator layout with the radiators directly behind the front suspension
1975 PH10C is a twin side radiator layout with the radiators moved alongside the roll hoop
In talking with Peter Hampsheir he indicated that many of the PH10B and C’s were converted to the front radiator design (PH8 and 10). But what I am listing here is just some info I don’t want to lose. If anyone has more info please share your info.
