jmf340 OP mopar J Joined: Jan 2005 Posts: 469 In a van, down by the river	I have a 69 340 Dart that I will be installing a 4 speed in. My question is which flywheel do I need to use with a stock set up and clutch? Is there an advantage to a heavier (50lb) variety flywheel? What was used from the factory, anyone know? Got Mopar???

You might try calling Brewers. I don't see an advantage to a heavy fw, but the steel fw is lower maintenance then aluminum. hope this helps 66 Belvedere Vert, 4 Speed/Jerico, slowly, very slowly, getting faster - NA LD Wedge New New Best: 10.56 @129 68 B'cuda 4 gear Jerico - Another New Best of 9.86 & Trying to slow up https://www.youtube.com/watch?v=T4jDLKwd9Gs

My question is which flywheel do I need to use with a stock set up and clutch? Is there an advantage to a heavier (50lb) variety flywheel? What was used from the factory, anyone know? For a stock to mild hp application, with no slicks, the stock 10.5" Borg/Beck style clutch is very adaquate. A heavier flywheel helps with low end torque but inhibits building rpm's quickly. A 69 dart is not a heavy car, and with 3.55 gears, or higher numerically, you want the motor to spin up quickly. Small blocks that spool up quickly are the most fun. If you were pulling tree stumps with a 3/4 granny geared 4 speed truck...........a heavy flywheel rules. R.I.P.- Gary "Coop" Davis 02/09/68-05/13/04
