1996-2002 Chevrolet Express/GMC Savana full-size vans
1996-1999 Chevrolet/GMC C/K full-size trucks
1996-1999 Chevrolet Suburban/GMC Suburban full-size long-wheelbase SUVs
1996-1999 Chevrolet Tahoe/GMC Yukon full-size short-wheelbase SUVs
1999-2000 Cadillac Escalade
The motor should have 5700 Vortec badging and was built under Regular Production Order L31.
F-BIRD'88 made a good point the other day, that the heads found in boneyards are more likely to be cracked than a new set of heads from Summit or another source. That's why the motor is in a boneyard in the first place.
Here's a good price from Pace Performance on a bone-stock head....

There are many other sources, including Scoggin-Dickey Chevrolet....

OK so I got the heads ported and polished cam is in and the double roller timing set is installed. 4 bbl intake and Qjet card is installed (was a 2 bbl) New high volt distributor is installed (was the old points style) Now I got 2 questions.

#1) What kind of breakin should be applied for the cam and which oil should I use for break in.

#2) Should I gain a suggnificant amount of horses changing from 2 bbl to 4 bbl and changing out the distirbutor from points to HEI, and from the ram horn manifolds to 1 3/4" shorty headers?

You want to use a Moly disulfide paste on the cam lobes.
(Isky rev lube or same)
You want to use a motor oil high in ZInc and Moly....or...
A bottle if GM EOS is nice.

I use this stuff in my oil for the cam break in,
www.molyslip.com Molyslip E Oil suplement.
They also sell the moly paste.
It works. Do not dump the oil after the break in.
Leave it in, with the Molyslip E additive so it can work.
You can change the oil filter if you want ...

Keep the engine rpm up above 2000 rpm for the first 1/2 hour.
Do not allow the engine to idle slow for the first 1/2 hour.

Set the engine idle speed to 1000-1200 rpm for the first 1000 miles of street driving. Until the motor is completely broken in.
Then reset the idle speed to around 700-750rpm.

F-BIRD'88, do you use the Molyslip E instead of the GM EOS or ZDDP additive, or in addtion to the EOS/ZDDP additive?

A complete guide to cam break in procedures and info is HERE. I realize that giving you links is sort of an impersonal way of answering your questions- but a lot more time and effort went into the links than I could give you in a thread post, so look at it as a more in-depth answer instead of an impersonal one.

Good luck.

Thanks alot for the links and the help its muchly appreciated thats for sure. If i didnt have all the guys on here that have helped me in the last 5 or so years I wouldnt know what I know today about what I know. Any kind of help is appreciated I know sometimes people on here can ask the most basic questions about the most simpilest things but there is always someone that can answer it wether its complicated or easy as changing a spark plug.

So thanks to everyone for all the help like I said it is appreciated
