Flywheels and big blocks, small blocks #219887 02/10/09 11:28 AM 02/10/09 11:28 AM

Reverend_Ron OP super street Joined: May 2004 Posts: 449 Friendsville, TN	78 Dodge D-250, 4 wheel drive, 318 4-speed. The 318 seized up and I am going to install a 400. I have the proper truck big block bell housing. I've never messed with or owned a 4-speed vehicle before; only automatics. 1) Do I need to get a different fly wheel or will the one on the 318 transfer over? 2) Don't I have to make sure the crank has a hole drilled for a bushing? 3) If "yes" to question 2, can that be done with the engine assembled? Thanks in advance!

If the 400 has a cast crank you will have to get the flywheel rebalance for the correct external balance. On the pilot bearing/bushing, no issue, just shorten the input shaft and use the magnum style that fits in the torque converter hub. If it is a steel crank 400 you won't have any problems at all and can use the flywheel as is.

I'm going to "GUESS" the NP435 because I had to get the "truck" bellhousing and not the car bellhousing. Is there a way to tell by crawling under the truck and looking?

Where is your shifter located in relationship to the transmission tunnel? Right in the middle is the NP435. Way on the drivers side is the 833. 435 has a granny low, 833 is usually an overdrive.

I crawled underneath and there are no shifter arms or linkage on the side - it's all on top.
