Mallory Distributor help.

I have recently bought a Mallory Distributor for my Y block (272) and wanted to know a bit more about it.
For starters it's a YC336HP, searched the web and found nothing!
I see people with YC311HP, is there much difference?
Any info will be appreciated, thanks.

Here is a thread that was started by Xon regarding his Mallory dual point unit rebuilt by Bubba. Worth the read and may help you out.

Interesting read thanks vtwhead.

 

Trevwood,

My catalogs show the Mallory 311 as being correct for the 55-56 272 and 292 engines.

The 336 is shown as a 57-59 312 application.
There could be a difference in the drive gear, lower end and oil pump drives between the two units..

I think the Y Blocks used a tang drive, and a couple different sizes of oil pump drives....????????

 

Good info GMC BUBBA thanks.
I'll be sure to check those areas out before using it.

 

Had some good info come from the Y Block forum that said there is no difference in gears and oil drive shaft between the 336 and 311, so it's good to go. Trev.
