The 383 for my '87 finally arrived

Any oilpan and oilpump recommendations? I would a little more than stock oil capacity but not at the expense of ground clearance. I'll also be running headers.

 

Hi
Congratulations nice engine
The only real thing to do is widen the sump and put wings on without going lower, see the sump on the corvette central website below.
Just have to check starter clearance before getting one made, or purchase one made for the car like the sump in the link.

Very nice!!

Details?

 

I chose the Canton pan because it was the only one I could find that had a pick up for standard volume pump with 3/4 inlet.

 

Do not forget to put a bolt in the hole on left side of engine looking at the picture beside the bottom left timing case cover bolt that hole goes into the manual fuel pump area, will squirt oil out and is a pain to get to when everything is bolted into place.

 

If I were doing a non high rpm tpi motor Id keep the stock pan make sure &use a windage tray though.

Kicked out pans can be a PITA...add a scattershield and they are a nightmare imo.

 

I agree. The stock Corvette pan and pick up design is decent and has good ground/header/starter clearance.. Not something I'd want to use in a dedicated road racing car, but plenty good for most cars on street tires.

On a recent 383 LT4 build I did - I reused the stock pan and pick up to save him $$$. I did utilize the MOROSO louvered windage tray. It fit well, was easy to set up (Milodon main stud kit) and only needed minor grinding to fit around the oil level sensor buldge in the stock pan. That car put down over 460RWHP and turns almost 7,000RPM with no oil control problems.

If you just have to have an aftermarket pan Moroso, Champ, Competition Componets, Kevco and Canton all mfgr road racing pans that fit in the C4 Corvette.

Thanks, its built by tpi421vette from this forum. I bought it 'secondhand' from another forum member. Spec's are

FIRST intake manifold, 4 bolt main block, Crower rods, forged SRP pistons, forged 4340 crank, AFR 195 (1040) heads, Crower 00483 cam (221in/230ex @ 0.05", 0.560"/0.580")

If I used the correct data, it should (maybe) have a hp/torque curve something like this (chp)



If its not necessary for the occational trackday use and spirited road driving, then I'll just stick with the stock pan.

Nope, I prefer to use money where they are most effective and I'll have less problems at the 24 months inspections the more stock my engine compartment appears to be.

That's my primary reason for keeping an TPI style intake. I live in Europe where the Corvette C4 is not seen that often and therefor not many people will notice the FIRST manifold instead of the standard TPI.

Any advice to which good quality oil pump I should buy?

 

Should be a strong runner!!

 

That is a blind hole on my block so I don't have to worry about it.
Thank you for the look out though

 

I prefer to use the Milodon oil pumps in high performance type engines.

Melling cut a bunch of corners on their regular oil pumps forcing builders to now pay premium $$$ for the "Melling Select" pumps when we use to get most of those features (the important ones anyway) in the regular pumps.... They also cost a bunch of builders some $$$ when those regular pumps failed and ate engines up.

You have a couple of ways you can go with Milodon on the oil pump.... without knowing what kind of brg clearance, oil and external coolers, ect you plan to run I can't say if I'd recomend a HV pump or not for you but the STD volume pump is usually more than adequate for most engines...

Milodon PN 18750 is a HV pump with a 5/8" pick up... you will need a Melling PN 55-S3 pick up tube if your factory one is like the LTX engines with a 3/4" pick up tube.

Milodon PN 18755 is a STD volume pump with a 5/8 pick up and needs the same PN 55-S3 pick up tube.

Milodon PN 18740 is the later LTX style HV pump with a 3/4" pick up. The Melling pick up tube you need for this one is Melling PN 254S.

It's a good idea to get a new pick up tube either way you go... they are only $12-$15 and a good peice of mind since they are pressed in the oil pump.
