MR1 BLOCK WINDAGE TRAY
Does anyone know of a windage tray that works on a MR1 block with a 4.75 crank?

They all will work. I use the PPR or short factory trays with the 4.5 stroker cranks. Don't use the factory dipstick set up. Have seen them crack even the PPR tray with longer stock modified mounting. Use the canton pan with their dipstick.
I use the longer carb studs with shims or oversize nuts and washers, then dimple the tray for clearance where needed. Especially around the oil pump location. |

The PPR short tray also know as the Tomahawk windage tray is no longer available from PPR as Ken is out of business. This windage tray is available thru Butler Performance and other Pontiac suppliers.

Paul Spotts and IA had a tray that fits them-would probably fit an MR block.

Have decided to ditch a windage tray on this build. Just going with a crank scraper with 4.5" crank. I/we have had several different ones and they all cracked. Maybe for street but not for racing for me. Maybe harmonics eat them up ?? Don't like bits of metal in my oil ....JMO..
To each their own.....
