340 Stroker Build Need LOTS of Advice
So I am resurrecting an old project of mine. I bought an old 340 motor from a friend, tore it down. Had it chem dipped and sonic checked, which turned out good. Then came into some money issues"got married" haha so I sprayed oil on the block, shrink wrapped it and put it away for a few years. Now its time to build again!
I am looking to do a 416ci build. Let me tell you what I have/want and maybe get some advice from you guys. It will be a STREET car, I want enough vacuum for power brakes.
The big questions I have are what cam shaft specs and what pistons to use. Hopefully be in between 10-10.5 Static Compression on +91 gas.
Here we go
~340 block .030 over
~Edelbrock Aluminum heads Performer RPM, Aluminum, Assembled, 65cc Chamber, 171cc Intake Runner
~Edelbrock 750 Carb
~Edelbrock Performer Intake
~Long Tube TTI Headers
I have never done the math on how to make a good motor, nor do I know how to. Mostly just throwing stuff together for old vehicles. But I would like to do this right, the first time.
These are the two rotating assemblies I was looking at. Big Question, Flat top or Dished Piston for the compression I am looking at.
