Hi all,
Well the engine is up and running -- Permatex Ultra Black is holding the coolant in on the damaged exhaust bolt holes -- and I've found and purchased two additional J302 cylinder heads as well.
Have, more or less, got the old 650 DP Holley dialed in; it's lean and clean at idle and pulls hard through the gears. Have thought about trying to setup the 650 HP carb but, since I've also got a Quick Fuel SS-750-AN for the engine, am thinking I'll just sell it.
Right now I'm tracking down an intermittent vibration in the drivetrain (believe it is either the accessory drive belt or a throwout bearing issue) and a significant
oil leak somewhere around the timing cover. Plan to replace the Gilmer belt accessory drive w/ a v-belt in the next week or so and am fabricating a return spring perch for the clutch lever arm. Hopefully the
oil leak isn't the front main seal, but... we'll see.
The new J302s have some bowl blending and short radius work, but are otherwise stock. Got flow numbers along with them which show about 245-250 cfm on the intake and 200-203 exhaust at my cam's max lift. Will see what they can do in the near future.
