I have been reading that an HV oil pump will suck a stock oil pan dry. Well I have a stock oil pan and was going to put it a HV oil pump. Should I get a canton oil pan, or ditch the hv oil pump and get the melling select high pressure oil pump, and stick with the stock oil pan... This is going on a built 355, with a front mount t76 (realquicks hot parts)

I can't comment on the pump because of the t76 but Stay away from moroso!!! lol my words of wisdom for the day.

You don't need an HV pump (I'm sure you have read about more reasons than just the pan issue). Use a Melling 10554.

I am sure that HV is bad for most NA builds BUT how about we specifically steer this towards builds that have something else like oh say turbos that need engine oil as well.

How much oil do turbos need? Is this a meaningful factor in selecting an oil pump??

Not saying I have the answer, just saw a variable not usually discussed. I have never laid a hand on a turbo so I really do not know.

So the melling 10554 + http://www.summitracing.com/parts/NAL-3848911/ (high pressure spring?

how your bearing clearances are set is a primary factor on weather you use a HV oil pump. With the Turbo in the mix...don't know.

I can say I have a HV with a stock pan and have not experienced the pan being sucked dry....at least according to oil pressure gauge under and driving conditions I have been in.

That is a valid point (I actually missed the notation on the first post ). A deeper pan for more oil (and heat dissipation) might be a good idea, but I think an SV pump would be fine, too. Just the serious drive gear wear I have seen would make me scared enough of the HV pump. Kind of a judgement call on this one.

The 10554 already comes with the Melling pink spring that is equivalent to the GM white spring (both 70#).

mel-10554 ordered. Thanks shbox! Slowly but surely this is coming together.

I'm using a High Pressure/Standard volume pump with stock pan on my turbo build. I also read using the lt1 stock pan with a HV pump can destroy the motor so I stayed away from it. I kinda wish I got an aftermarket pan just because I had to do so much clearancing, but what's done is done. I'm a 383 though so you shouldn't have a problem with your 355.

be glad you didn't LOL I wish I had not goten my moroso pan. nothing fits. The cantons look likr they fit better than this pollished turd.

Cantons leak and the windage control is nonexistent.

I think every aftermarket pan has problems, pick which ones you want to work though.

There is a Stef's for the b-body and my understanding is it needs thicker endseals and LOTS of "right stuff" to seal.

Stef's and Canton have been known to need a little silicon on a weld or two as well.

I had a Moroso on my 383 LT1 and it was great. It cleared my rotating assembly and did not leak.

It is a good idea to have a great high flowing oil pump for a turbo build especially if you are going to use that turbo to its capacity. It will need a good amount of fast flowing oil, I would get a high pressure pump more than a high volume - but that's just me.

I would also add an external engine oil cooler like the biggest bar & plate one from B&M with the built in electric fan. I'm using the melling 155 with the 3/4" pickup in my new 383 build.

i agree about the windage problem of the canton pan... having issues with it myself. I think you just have to run them low on oil, defeats the purpose of having a 7qt pan though...

i had a HV pump in my old setup and like shbox said it wore the drive gear and eventually destroyed my motor....after new bearings and a rebuild I went with his recommendation on the 10554 pump and my oil pressure is still great and I have had 0 problems with it since....
