What's up guys? It's been a long time and a long way since I posted in this forum...
I played a lot and have fixed a lot with this car and motor since I've been here last.
I'm beginning to generate some decent income and I would like to replace my motor, torque converter, transmission, and upgrade my rear end or replace it.
I've learned that my 305 is a 1981 LG4 with L69 (H.O.) heads. I replaced the camshaft in February with a Comp Cams 260H camshaft and lifter kit, 212 int./212 exh. @.050" lift. Still the same Edelbrock Performer EPS Intake Manifold. Replaced the 750cfm Edelbrock carb for a 600cfm 4160 Vacuum Secondary Holly/Quikfuel. Timed at 12° initial, 34° total.
Transmission is a BOP THM350-C with a stock 1397 stall 30 spline lock up converter.
Rear end is a 7.5/7.625 10 bolt with a 2.41 gear ratio, non posi peg leg.
Right now, my top speed is 104 @ 3300 RPM...I'm being told the 2.41 rear gears are too much/too tall for my 305 to go any faster or higher in RPM.
I have a vacuum secondary opening issue with my carburetor. The housing whistles because I lost a check ball to the vacuum secondary housing...not sure if that would disable the vacuum secondaries or not, but it wasn't whistling until I removed the housing to install a new diaphragm and quick change kit, not aware of the check ball. I'm also told with my 305 and my max RPM only being 3300, it may not produce enough vacuum to open up the secondaries.
Transmission I don't know much about other than it's a BOP THM350-C. Torque converter is a 1397 stall lock up converter. 3spd and a small converter also not matching up to the too much/too tall rear gears.
I want to swap it all out and upgrade it all.
