NOT a Camaro Motor

Looking for some advice:

This Spring, I hope to build my first motor...

It will likely be for a '67, 4 wheel drive stepside Pickup.

The block is a 400ci GMPP replacement motor (I cannot get to it to look at the ID numbers right now, but I am told it is a "high Nickel" block, whatever that means--it is a two bolt main block, and has the rotating assembly with it.

I am looking to rebuild using a pair of 882 heads...

I don't need crazy horsepower numbers, but do want it to perform well in the truck..thoughts on cam? Roller or flat tappet, lift, duration, etc?

Also, if not boring the motor, what can I expect machining to cost--cleaning, fluxing, etc? What else would you recommend on the build?

I thought about that...I also have a pair of 462's and a pair of 461's on the shelf...

Thought the 882's might be a better match for the 400 than for the 350 blocks that I have...(in other words), i'd rather the 462's or 461's live on a 350 block, once I cut my teeth on the 400!

Not looking for crazy performance, but a decent powerband for a pickup would be nice

Re: NOT a Camaro Motor

Keith,

You can probably figure on spending about 100 bucks to clean the parts, inspect them for cracks, and to mag the heads.

The 882's are an okay head for a stock or mild performance build....they do have a rep for cracking. That of course doesn't happen a lot, just more than on other heads from the day.

The 462 and 461 heads are the old camel back or double hump heads from the mid to late 60's. either of those castings will be okay for a mild build-I use them on all kinds of engines-race, street, hot rod, whatever...but there are better choices available for what you are doing. You can use Vortecs or RHS heads which are much better in quality and configuration and the cost will be about the same as going through a set of old OEM heads. For a valve job, guides, truing the heads, etc...you can spend 600 bucks or more.

The high nickel content of the block means it is pretty strong for a production OEM block.

As for your cam, most people like using hydraulic rollers..they will cost at least 2x what a flat tappet cam and lifters cost, and a lot of people use the roller set up since the oils today are lacking proper quantities of certain minerals for lubrication-

I use flat tappet cams exclusively and use Brad Penn oil, never had a problem. Good oil can be hard to find.

As for the cam profile you will have to determine what power level you want. And, to be candid, you should contact a cam grinder for your specific needs. I use Bullet cams in all my stuff, I would call them and ask for James.

Re: NOT a Camaro Motor

Just looking for a mild performance build, maybe a step or two over stock...just have no idea what to look for in a cam for a truck...

Re: NOT a Camaro Motor

Trucks come from the factory with big torque converters...I suppose for the low end towing. Since your truck is 4 wheel drive you probably want to stick with a cam that makes some low end grunt.
