Default 383 Stroker - L98

Hi everyone,
I am building a 383 Stroker out of my 1985 Corvette L98 block. I have just installed my 6 3/4" harmonic balancer and wondering if my stock L98 oil pan can be used or will the 400 crank interfere with factory oil pan.

My stock 86 Vette pan worked on the 415 I built for the same car. Even the 6 quart GM pan I bought later from Scoggins-Dickey fit without a problem.

You should be able to make the factory pan work. Some dimpling with a ball peen hammer may be needed, but most times not likely.

Check to be sure. Put some marker or dye on the pan, especially by the oil filter area, then turn the crank over.

My stock 1990 oil pan worked with my 3.75 eagle crank. It only needed a few wacks from a hammer on one point near the dipstick.

You know, now that I had time to chew on it, I did have to hit the pan a little - yep same ball peen hammer trick - in the area of the oil pump. As I recall now, now that Pete K turned on the light bulb in my brain, it was the after market oil pump that needed a tad of clearancing.

It didn't take much and completely skipped my mind (such as it is, LOL) since I hadn't thought about this in so long a time.

No grinding on the block was needed though and I don't even have to do anything to the oil pan gasket.

Sorry for any confusion this may have called.

Thanks, Pete. Maybe I should put you on retainer, LOL

Every build is a bit differt. I once had a crank counterweight nick the oil pump. I put the grinder to it, and it was fine.

I just did some fitting and the connecting rod bolts are hitting the oil pan when I spin the crank over. I have identified that the bolts hit in 2 difference places and thinking that there may be more that are close.

I am looking at an after market oil pans, but there is not much clearance between the front of the engine and the cross member. Which Moroso oil pan will fit? Are there other types of oil pans available?

Does any one here on the corvetteforum work at Moroso?

You could call moroso and ask "i have a (example) "383 with 6 inch rods, do you have an oil pan that will clear my setup" blah blah and they will probably have an idea

Thanks. I have emailed Moroso with a description of what I need. They have not responded.

Thanks. The below SES-3-60-08-380 has a one piece rearmain seal and mine has the 2 piece rear main seal. I did some research on the summit racing website and found this oil pan

While everyone works out your bottom end issues, what kind of intake will you be running?

I was looking into this for my 383 build as well only I have a 70's style block with the driver side dipstick. That is the only pan that I was able to find. I also had another guy recommend Champ Pans to me. I dont know if they have anything but I believe they can do a custom pan for fairly cheap. I have not looked into it yet though. Otherwise that Canton Racing products pan looks to be a great pan and will probally be what I end up going with for my build.

Isn't your crank a 1-piece RMS version? If you're looking for a direct bolt-on pan, the pan you linked won't work. It's for a 2-piece Rear Main Seal crank.

With the low cross member clearance, oil cooler lines and the high potential of needing to do some modifications to a new oil pan, the ball peen hammer trick is on the table. I will do some more research.
