One thing leads to another... mean 318?

All of that is understood but the reply contains to many what if’s. It adjust the what if’s it becomes a matter of build the engine properly for the goal at hand for the arena your going to be in.
Should an engine be built, stroker or not and the power curve starts high, dips low, rises back up with the rpm, it is ether a tuning issue or the build is off balance. This balance will need to be adjusted via ether the engines bore and stroke to use the parts within better or the parts used within and around the base engine.
IE; Wrong intake, cam to large, etc...
Looking forward to this mystery mans thoughts.
LOL it’s not a mystery man. It’s Harold Bettes.
And I agree. Too many guys just decide on engine geometry without a single though of chassis and gearing. That’s insane. Since my first build in HS everything is dependent on how much gear/converter someone is willing to use. Many guys claim to love a set of 4.56 screws, but when they drive it, their butthole puckers and out they go, 3.23’s go in and they can’t understand why it’s a pig.
My cousins husband burned me on that. Car had 4.11 gears and a stick. I spent several hours with him before the build happened and he was dead set on leaving the 4.11’s in there (BBC BTW) so I built the engine accordingly. I make it run, sounds great, runs even better.
Six months go buy and he calls me up and wants a tune up because “the damn thing is down on power”. I’m thinking this joker lost a cam or something. So he drops it off and after work I drive it. What a slug. Wouldn’t pull a hat off your head. I’m thinking what super hero did his last tune up? I’m sitting at a light thinking it over and when I go to leave the light, I realize the thing is acting like it has 3.55 gears or something. Did the dumb *** maybe switch to a close ratio gear box or what?
So I get to a nice country road and wring it out a bit. It will easily run over a hundred in third gear. And it pulls hard once you get it moving.
So I pull over and all him and ask if he changed ANYTHING on the car. Nope. Really? Nope...nothing. Big pause. Well...I did have a guy drop in some 3.23’s for me because everyone said the 4.11’s were too steep for the street!!
This guy makes better than 200K a year, and he just didn’t listen. We used a port I’d have never used if it weren’t for the 4.11’s. And I would have different intake too. And the cam for dang sure would have been different.
The same super hero who told him to change gears told him I was an idiot and gearing doesn’t affect horsepower like that. I said no ****. It affects DRIVEABILITY. And that’s the issue.
The same super hero changed out the heads, cam and intake cousins husband says it still doesn’t run as it good as it did at first! So I told him his super hero was right. I am an idiot. I should have NEVER even touched that job.
So it’s all combination dependent.
