re: What rear end gear ratio to choose?
OK, it looks like I'm going to a slightly beefed up TH400. Based on the calculator you suggested (by the way thanks!), with a 3.73 it looks like 67 MPH at 3000 RPM. A little high, perhaps, but workable as street car? A 3.55 gets me to 70 MPH at the same RPM.
So a 2400 converter is pretty conservative? Will going to a 3.73 dampen the slipping effect?
By fighting the engine, do you mean having to "punch" the engine to get an reasonable rate of acceleration?
Yes sir, it's a street car. TH400. Cam is a Lunati with a .54 lift in and .55 lift ex. The guy who built the engine indicated that this engine's torque curve is at a higher RPM, which (if I understood him correctly) is the reason he selected a 2400 converter. Sound correct?
Yeah, an overdrive would be cool! Solve all the problems! Are you running a standard torque converter?
