ouch

Thanks. Mounts were stopping all real progress. Whats BAT?

Sorry for the delay. Yes when you stroke a motor you need a deeper shallow section of the oil pan. This gives clearance for the longer stroke of the crank. And yes my oil pan was touching my crossmember. If I had the original 6.2liter crank they make a shallower thin section pan I could have bought. I just fixed that issue. I had wrong mounts. I knew I needed tall and narrow mounts but ordered wrong kit with adapter plates and short and wide mounts by mistake. Now all good with frame clearance but hood is going to be close. Will be putting on carb and air cleaner soon. Hood will be off for a while longer while waiting for new hinges.

I have the thinnest pan available for a stroker. It's slightly deeper than regular Muscle car pan.

I installed LS3 427 last week. Everything looked good. Put transmission in yesterday and now have oil pan clearance issues. Previous engine was 350. I am using Tall and Narrow energy suspension motor mounts. Oil pan looks like it just touches frame. I can't go with any shallower oil pan because of stroked crank, so I have to go up with engine. Has anyone had experience with this? I heard that a Chevelle sb 307 had taller frame brackets, but shallower motor mounts. If that is true combining taller brackets with my tall mounts might work. Shimming brackets and or motor mounts is what I was thinking. If there is off the shelf parts I could order that would be my go to. Cutting frame is not an option for me. Experienced input would be greatly appreciated. Will post pics later. TY.

I might have to get one. Just put in stroker LS with high rise intake and carb. Stroker pan just touches frame so i have to raise engine. I have no experience with any fiberglass hoods. This is the one i was looking at from US Body Fiberglass. https://usbody.com/product/1970-1972-chevy-chevrolet-monte-carlo-fiberglass-hood-2-cowl-induction-style-bolt-on-heavy-duty/ . I like the look personally. I'll be following to see recommendations.
