CNC BLOCKS
Well-known member
Spent some time on the dyno yesterday on a SBC 427 build for a good friend of mine. He wanted a SBC with BBC torque down low for his street build. This engine laid out some impressive numbers.
Was a very efficient engine only required 32 degrees of timing it did not like 34 degrees and it did not like 30 degrees.
This is what I came out with and it was no budget build LOL.
This is also on my F/B page with a lot of pics of the build https://www.facebook.com/cncblocks.northeast/posts/856106251235885?pnref=story
This will be the only one of these I will build I can take it off my bucket list as I have wanted to this build for a long time and it came out as planned.
Dart SHP block 3.875 stroke X 4.185 bore sonic tested 3 blocks and this one was the best one
.
Callies Comstar crank
Scat I beam rods 6.0
Custom Wiseco dished pistons.
Ultradyne HYD roller on a GM step nose core I used the GM spider and GM roller lifters reduced the base circle to 1.050 Lifters were quiet block need no oiling modification LOL

Eddy Air Gap intake
750 Quick fuel carb, Wanted to go to a bigger High speed air bleed but the customer said leave it alone it was fine.
