Engine Break-In Procedure
Use conventional or break-in oil (non-synthetic) for the first oil change, be sure to check the oil level in the engine and prime the oil system with an engine priming tool.
Engines with flat tappet hydraulic cams only - Run the engine between 2,000 and 2,500 RPM's, with no-load on the engine for the first 30 minutes. This is critical to break in the camshaft.
Drive the vehicle with varying speeds and loads on the engine for the first 30 miles. Be sure not to use a lot of throttle or high RPM. Run five or six medium-throttle accelerations to about 3000 RPM (40 to 50 MPH), then letting off in gear and coasting back down to 20 MPH. Run a couple of hard throttle accelerations up to about 5000 RPM (55 to 60 MPH), then letting off in gear and coasting back down to 20 MPH.
Let the engine cool and change the oil and filter using conventional (non-synthetic) oil and check coolant level, top off if necessary. Drive the next 500 miles normally, without high RPM's (below 5000 RPM), hard use, or extended periods of high loading. Change the oil and oil filter again using conventional (non-synthetic) oil. Keep an eye on oil level during the first thousand or so miles.
It would be suitable to use synthetic motor oil after the second recommended oil change and mileage accumulation.
Does this engine require an oil filter adapter? If so, what's the PN?
I have a 1984 Transam LG4 and the engine is shot (300k, body is immaculate).Will this go in as a direct replacement? also, what extras do i need to purchase to do the whole job in one hit or are there existing parts in my car i can use? Thanks
I've been thinking about installing the Holley Sniper EFI system on this engine. Been told that the cam has to be matched to the sniper system. The camshaft has to have a 114 lobe separation or the engine will not run right. Will it work?
Does this engine have the same 3 year 100,000 mile warranty as the base gm crate engine?
What are the 4 brackets found on the top of the valve covers used for? Can they be removed or do they serve a purpose?
If i swap this on my 84 monte carlo ss, would i be able to reuse my stock intake, stock e4me qjet carb and stock distributor (no vacuum advance) without any issues?
Can I use a Holley 600 cfm with a edelbrock eps intake for this engine. Chevrolet recommends a 670 Holley.
Can I modify the block
