That 29 degrees number was just what I have the best power and torque with on the dyno. Every combo is different what is good for mine may not be good for yours. Is your 400 stroked and bored to 463 cid now or is that a planned build?
yes build complete...I hear ya. I am just trouble shooting.
Your 62 heads will have a small chamber, 72-75 cc, it may not be the timing that is giving you the detonation but the compression. A lot of factors to consider when facing detonation, grade and quality of fuel, quench, heat dissipation, static and dynamic compression ratio, timing, driving style, weight, gearing, cooling, etc.
heads are 74cc and yes still working a lot of this out. Been a long process and not done yet. working on a low fuel pressure issue now when hot
You say you want high torque from your engine. That's a rather large camshaft, good for high rpm horsepower but you'd most likely get more torque at lower rpm with a smaller cam. I don't know how the 62s flow but you'd have to flow fairly well to use that cam.
When I say a lot of torque I meant it is what I believe makes a good driver not necessarily looking for a diesel truck. I was blinded by what I had at beginning of build and a desire to keep a nice car fairly stock..hence cast iron heads and the old holley street dominator intake. She is a good driver. I had a buddy wanting to sell me a well built LS1. I guess I just like spending money. :-(
