Great explanation of what I've been telling people for years..... Too much cam and not enough head loses everywhere, too little cam and too much head is a better balance with room to grow. Always focus on increasing average torque instead of chasing peak hp.

I've noticed a over kill head for a given displacement will gently fall off up top vs a less than ideal head will just hit a wall and fall of sharply up top. Even with a larger camshaft.

@hughobrien41392 жыл бұрын
I love it! Great explanation on port development! When I started out porting I spent very little time on conventional cylinder heads. They stuck a grinder in my hands and said to do this and not that and walked off. Had some success with those ports and that was about two or three sets, then it was all Big Chief and Big Duke from there on out. I had very good luck finding my way around those ports. Mostly figured out that the majority of them had subpar valve seats and back cut angles. After about 10 years of that I grew worry of it. Always something bigger and always something better. Most of all if you can’t dedicate the R&D time to it at that level you’re pissing into the wind. Talking cross sectional area with me at that time was a one sided conversation. You could go on and on all day long about it, I would just shake my head and keep quiet about it. It did not affect my world then. I must add that I would have made a mess out of those valve seats without a chamber valve on those seats. Looks nice! I’m betting there’s more than just plus 30 cfm improvement there. That’s an easy 50 cfm in Texas. LOL!

@timothybayliss66802 жыл бұрын
ProTopLine had a set of bead blasted heads that were to cheat the "unported" rules for some circle track sanctioning bodies. The bead blasted surface is more akin to a cast surface than a burr or flap finish. Extrude hone is another thing. Sandblasting is an idea but it almost doesnt remove material. The pushrod pinch he took out 1/8" material, a sandblaster would take a really long time to do that. Even just attacking with flap wheels would probably be faster and way more cost effective.

In some cases yes but on a small block chevy this doesn't work. We could use offset lifters, offset shaft rockers and then weld up the port at the pinch. This would provide large gains.
