427 sbc build

Hi, I am looking into a 427 sbc in the future and getting some ideas price and quality wise. I have looked into Shafiroff, which has a good rep but may be a little high pricewise. I have also considered finishing the build from a shortblock and have looked at Dart for this. I am not wanting to cut corners but at the same time don't want to start divorce proceedings over it. Any suggestions appreciated.

Re: 427 sbc build

Carolina Machine will do one built to your specs. They wanted to do that with mine but I didn't see any reason to max out the stroke right off the bat especially with a street only engine....left at least a little room to grow on the Dart block. Their link is in my signature.

If you have someone do it and go with and SHP block, all forged assembly, roller cam, and good aluminum heads you're looking at a bare minimum of $7k for a dyno tuned package.

Re: 427 sbc build

I am not a big fan of putting a 4 inch arm in a 9.000 deck block with a standard cam tunnel as you end up with a cam that looks like a pencil and lifters hate small base circle cams and there is a lot of clearance work as well and a stroker oil pan is needed as well.

That being said we have built quite a few 421's 3.875 stroke by 4.155 bore and we have been using the callies rotators and have gotten away with a 1.000 base circle cam!! and a standard oil pan as well. And this rotator will fit in a Dart SHP block.

Now we also have a 427 we are building using a Dart Iron Eagle block 3.875 X 4.185 bore that block uses a raised cam tunnel and spread pan rails and we are using 18 Degree heads on this build.

Hope this helps
