TC I can't seem to get across to you I don't care about stroke except that it limits your total cubic inches when your stroke is shorter than the block will allow. When I am building an engine for horsepower I want the maximum c.i. I can get if not limited by rules. I assume your turbo motor is not limited this way since I don't recall that it is being built to fit any racing class.
For your application I would build the biggest engine I could and if it is too much for your chassis I would dial back the boost to make the engine live longer.
Can't you admit that a 421 or 427 sb will make more h.p. than a 358 and will accelerate your car faster all else being equal?
My wife is uncompromisingly pigheaded but even she can understand this.
You come on here bragging about your short stroke Nascar crank and can't seem to comprehend that it is limiting the h.p. of your benchrace engine. And I call it benchrace because it will never be finished like all your other projects that you have most of the parts for but are just sitting.
If you spent 1/10 the time wrenching as arguing your stuff would be done and worn out by now.
As for tire diameter, you should know this..... A 28" tall tire has a circumference of 87.96", a 31" tall tire has a circumference of 97.40", so for one revolution of the tire the taller tire contacts the ground 10" longer.......

So....what does this have to do with how much power the different size tires deliver to the ground?As for tire diameter, you should know this..... A 28" tall tire has a circumference of 87.96", a 31" tall tire has a circumference of 97.40", so for one revolution of the tire the taller tire contacts the ground 10" longer.......
Words like "power" mean something specific when you're talking about machines. You need to understand what the words mean.

Geeze, Its a small block Chevy, there are no secrets, grab a magazine at Walmart and go from there.
As for the tire height, I'll have to dig up the article again, it has to do with the taller tire covering more distance per tire rotation, which effectively transfer more torque to the ground per tire rotation........
