Update.
The Skyhawk is back on the road; Now w/ 10.25-1 and polished pistons. Installed an Accel vacuum advance and no ping running on Phillips 66 premium grade. I polished the combuston cambers and used a .040 head gasket. Yes, a Buick V-8 can get away with it ! Cleaned up the ports and matched the intakes w/ the TA aluminum intake using the composite TA intake gaskets.. Had the intake port bowls machined; the machinist said the exhausts were good enough. The 750 cfm Edelrock dosn't bog or wheeze. ! While I was at it, I cleaned up the exhaust manifolds because no headers are available for this conversion. All this w/ reconditioned rods,new cap screws and the rotating assy was balanced. I bought the kit from PAW.
Have changed from a Poston GS 114 to the GS 118 camshaft. My biggest mistake. Boy does it sound nice w/ a great rumpty-rump idle.
Even using a TCI 2000 rpm Saturday Night Special torque converter it shakes like a ***** below 2200 rpm. She pulls really hard to 5500 ( my max, so far ) The overlap
is the culprit. The GS 112 is a super cam !
The guy at Poston was shocked to find the cam worked so well on the old, tired, 8.5-1
engine. ( only 2800 lbs helps ) He thought it would have been a dog.
I plan to advance the cam 4 degrees before I give up on the GS 118 and go back to the 112. The motor pulls 12" at idle and around 15" at cruise speed. My vacuum operated stuff works fine. Mileage isn't bad until I put my foot in it. Then I literally watch the gauge drop .
The car is no drag car. In fact, I'm a little afraid to buiild it to hook up. The
"Holy twisted frame, Batman" has deep meaning to me. I an not interrested in anything more than sub-frame connectors. And the way this car spins the tires is just fine w/ me! I have noticed that most Mustang owners won't even look my way at a stop light! I will take it to the strip in the near future. With no open exhaust and 245x60x14's w/ a 2.93 posi my keep my et's up, but WTF ? Hoping for 100mph trap speeds.
I'll report back.
