Chevy 396 Stroker Question

[Sajomatic]

I have a friend who wants to build a SBC 396 stroker. He is looking at a Scat 3.875 stroke crank and the Scat ProComp 7/16 stroker rods. He wants to run a solid roller cam. Will a small base circle cam be needed? Cam will be around 265 @ .050 , .650 lift and a 106 centerline.

[DaveMcLain]

.900 base circle with a .430 tall lobe should clear with that rod and little or no work.

[steve316]

Run a 283 rod journal crankshaft with compstar rods they will clear a standard base circle cam. less bearing speed & larger base circle a win win.

[DaveMcLain]

That's about the best rod there is when it comes to clearing the cam.

[wyrmrider]

SBC journals are 1.868" in diameter or .934" in radius.
Big Joe says he runs .900 base circles in 383's
.930 can work with rods designed for strokers
I like the small journal idea
sometimes 4" strokes take a .875 with Eagle H beams
Measure twice cut once

I seem to remember the 10.5/1 650 HP pump gas 396 that Terry Walters and I did a few years back used the Scat strocker clearanced rods and had very minimal clearance problems. It's a little cloudy here since my still recent brain surgery but as I recall we only had to grind a little off the rod shoulders to use a stock base circle. Mr. Mike Jones Sir -- can you throw any more light on this situation - I'd hate to be giving the wrong info here.

AS for the cam you are intending to use this will work just fine so long as your build is given a decent CR - that is to say between 13 and 14/1

A 420 cid BBC can't get 14:1 compression and will be lucky to get 13:1, How many inches was yours David?

Yes for some reason all the photos are gone but this from the article.

Now we come to the rods. This is a critical aspect of the build. The problem with many rods is that they require a lot of block cutting to give the bolt shoulder clearance with both the block and the camshaft. In addition to this, the bolt head also runs into the pan rail so that also needs to be cut for clearance. The Scat stroker rod aggressively addresses these issues. By utilizing top-grade material for the rods, minimizing bolt thread engagement to the shortest length possible without compromising strength and a compact design on the cap’s bolt platform Scat has reduced the rod’s mass in the areas most critical to a stroker. The result is that the rod actually has as much as 0.060-inch clearance with a stock base circle cam.

What my boss told their boss!

Luke4 5And the devil took him up and showed him all the kingdoms of the world in a moment of time, 6and said to him, “To you I will give all this authority and their glory, for it has been delivered to me, and I give it to whom I will. 7If you, then, will worship me, it will all be yours.” 8And Jesus answered him, “It is written,

“‘You shall worship the Lord your God,
and him only shall you serve.’”
