Hi Again Ray.I put my F in storage in 1981 .Saving it for a retirement project! One of the main reasons was lack of good Fuel. Cam2 was a option at around $2.00 a gal. But at 4M.P.G.and you were never sure you could get it on the other end.I am currently in the planning stage of the restoration .One consideration is I live at see levial -the shop is at 3000 ft.-the pass over the mountain to Nevada is 8000 ft. A b/map sensor will solve the main problem.But that means F/I .The throttle body F/I would be a way to go but balance with two on long rams is something I don't want to even think about.I suppose one could split the system and run it as two 4 cyl.engines with 2 of everything (oxy.-maps-temp-knock-sensors ect.) But E.F.I sounds like a better way to go.Sort of hate to drill the long rams for the injectors but I have a spare set and the holes can always be plugged and tigg weleded.I prickled the engine when I put it away so when I tear it down will go with the hard seats.Your solution to the octane problem sounds like a winner. I knew someone out there had tackled it.Now has anyone out there tired a NASCAR type rear end .Full floater with discs? And what about body reinforcement at the front of the rear spring mounts.Ive sean too many F and G with cracks at the top of the finders by the rear window ! Torque is wonderful but it can be a problem. Jim. --- --- macthehammer@xxxx --- EarthLink: It's your Internet. [Non-text portions of this message have been removed]
