here is the deal: i have a roller 350 block that i am in the process of building/stroking to replace the tired 406 that's in my s-10 right now. i bought a main girdle for the 2 bolt- and the stock late model oil pan won't fit around the girdle. it's my understanding that girdles always require some "massaging" to get them to fit correctly- is this true? also- will the 400 oil pan i have now fit on the late model roller 350 block i have? if so- is it any wider or have the strengthening ribs that the 350 pan apparently has. i can't see any of this first hand as one of my friends that teaches auto shop at a college 2 states over is doing the machine work for me. he is a mopar guy- so he doesn't know much about the chevy oil pans. he says we either need something a little wider or no strengthening ribs in order to get the pan to clear- or at least clear with a less grinding involved. he also said the oil pan that he has there at the shop for a late model roller slants inward a little- and he thinks the 400 pans don't do that- anyone want to confirm this?

 

ok- found answers to part of my questions- i know i have to have an oil pan for a late model block (1pc seal). anyone know what oil pan- either stock or aftermarket- has the most clearance at the top?

 

You would have to look at the oil pan sites to see which ones have been clearanced for strokers and for wide pan rails.
