Re: 383 kit I ordered today (Nathan Plemons)
Just a warning. Your high volume oil pump might cause you some problems. Are you planning on a larger oil pan? I know at least 3 people who have put in a high volume oil pump and then ruined their motor immediately. Essentially they just pumped all their oil up into the valve covers, and burnt up the bottom end.
One guy I know who did that is on his second stroker kit. The first 383 lasted 16 minutes before it was destroyed by lack of oil, high volume pump. Note, he was in a road race, so he was probably at WOT all 16 minutes, but still. He has a larger oil pan now. I think there are also some things you can do to the block, kinda like smoothing up your heads, smooth up the block so that the oil drains back much faster.
Just a thought, I'd hate to see you burn up your new stuff.

Re: 383 kit I ordered today (MrJay)
It looks like you got a good price on your parts, I think you can even save more by not getting ARP bolts for the block since you got new rods they will have good bolts in them.
Are you going to balance the engine externaly? if so then you will nead to get a new balancer and flexplate because you cant use your other balancer and flexplate if you want to use them then you have to have the engine internaly balanced.
It does not look like you are going to change the cam bearings in your parts list I would change them if I was rebuilding that motor and I would put in new freeze plugs too.
Good luck with the rebuilt

Ok, since so many people are agreeing on this, I'll definitely not use the high volume oil pump in that kit. I guess I'll just try and sell it in the parts section or something and get a stock oil pump.

Re: 383 kit I ordered today (Glock'94)
Here it cost about $50 to hot tank a block and I think the cam bearings are about $20 and the plugs are about $15, but I dont know how much it will cost to put them in.
So I would say it is more like $100 to $150. and the last 400 crank we had internaly balanced cost us about $300, each malory cost about $50.

Re: 383 kit I ordered today (Vette92)
Are you guys talking about the high volume pump being bad thinking about a high PRESSURE pump instead of VOLUME?
Because I can understand a problem with high pressure, but a high volume pump isn't going to pump anymore oil up because of the restriction of the oil system.

Re: 383 kit I ordered today (Glock'94)
I had the same questions, I talked to a guy running a 400 block with a .030 overbore in his Camaro(best run 8.86 @ 153), and he specifically told me to get a High Volume pump and make sure I don't get a high pressure pump, because the oil will go up faster than it can come down.
Even with my high volume pump I'm making 70 psi of pressure at start-up.
Scorp(I think it was Scorp) did some research and found that you can run 5.5 quarts of oil while still staying below the windage tray, so I'm doing that... No Worries yet.
There should be a pin with your oil pump so you can turn the pressure down, at least thats how my Melling pump came.

Re: 383 kit I ordered today (NoWorries)
Obviously because Big Blocks are way too hard to fit in a Corvette.
Several guys in this forum have the 396 "upgrade"; I'd like to do that myself...Most of what you have to do are the same for the 396 as the 383...Longer rods; bigger pistons; clearanced block; etc...
I haven't gotten into it really deep, but a 396 shouldn't be all that more than a 383...(All mods being equal)...

Re: 383 kit I ordered today (Rich B.)
383 = 3.750" stroke crank and a .030" block
396 = 3.875" stroke crank and a .030" block (+.040"&3.875" stroke = 398 ;))
The 396 Cranks are much more expensive than the ones you can get for 383's.
You can go as high as 421 from what I have read. Not sure wat it takes to get there though.

Re: 383 kit I ordered today (I_HATE_Mustangs)
So I guess my 383 with a high VOLUME pump is an exception with just over 4,000 miles on it and a few passes down the dragstrip....
I am just going by what happen to me.. many others like yourself may not ever have problems with a HV pump.. I am just basing my judgemnet on my OWN past experience.
Also I thought the HV pump really was only a benefit in the higher rpms? yes/no?
:confused:
