My 1972 F7 Dart Swinger
My repaired covers from legendary showed up this morning. I'm hoping to get the seats finished up this week!
I spent the weekend pulling my engine out of the car. I wasn't happy with the power level. Now I'm looking into options to get my CR up. I measured each piston to see how far in the hole each one sits.
#1 - .098
#2 - .095
#3 - .092
#4 - .094
#5 - .100
#6 - .107
#7 - .101
#8 - .102
I talked to Wiseco today and was told those numbers are pretty typical for a 318. They offer a kit that includes taller pistons. With the kit, I'd be at around .020 - .025 deck clearance. From there, I would need to decide if I should use taller yet dome pistons or just have the block zero decked at that point. Really depends on how the heads CC.
I was also able to make some headway identifying the cam shaft thanks to the community here at FABO.
1.571 - Base Circle & Lobe Lift
1.253 - Base Circle
1.571 - 1.253 = 0.318 - Lobe Lift
.318 x 1.5 = 0.477
likely a MP P4452992 . Trying to decide if this is too much cam for my build.
I also dropped the X-heads off at the machine shop this morning to have them looked over and have them CC'd. The goal for this engine is 9.5:1 to 10.0:1 with a 1900-2200 stall and 3.23 gear set
