One thing leads to another... mean 318?
Stroke makes cubic inches. What does cubic inches make? I'll just wait right there.
You’ll be waiting a long time Rusty because I’ve laid it out as simple as possible. Don’t take my word for it. I’ll post up what Harold Bettes put in print. Anyone who builds engines and doesn’t buy the marketing hype will tell you Harold is 100% correct.
Displacement does NOT make horsepower. That’s a magazine lie. Again, I’ve laid out what makes horsepower and it ain’t stroke/displacement.
Let me ask you this Rusty. In the unlimited dollar world of Pro Stock (or ASScar because it’s essentially the same issue) where the ONLY limit on displacement is displacement, why are they running the biggest bore they can squeeze onto a 4.900 bore center and then adjusting the stroke for final displacement? They ain’t stupid. Best last known by me geometry was a 4.700 bore with a 3.600 stroke for 499 inches. That’s a bore to stroke ratio of 1.3 and a 340 is only 1.22 as an example. A typical 408 has a B/S ratio of 1.0075 which is damn near square.
Do you think the PS guys are morons? Do you think they don’t understand the relationship between horsepower, stroke and RPM? I’m betting they do.
If stroke was a world beater, why doesn’t Pro Stock drop down to a 4.500 bore and a 3.900 stroke and rotate the earth with it? Because it would be a pig. A slug. Nothing in the rules says they can’t reduce the bore and increase the stroke and will all the trophy’s and take all the money. But they don’t. Are they stupid, or do they understand something you don’t? I would never have them balls to call any Pro Stock engine builder stupid. But that is essentially what the over stroke proponents are saying.
One last example. I forget the year, but it’s easy to find it if you want to know. Bob Glidden showed up at Woodburn the week before the Seattle nationals with a not yet legal 5 speed to do some testing. Since it was a NHRA sanctioned track, he had to unhook the 5th gear lever. It was a liberty gear box.
I was on the starting line for the 2 runs he tested it. I’m sure WJ and several others were doing the same. Anyway, his 60 foot times and incrementals told him the 5 speed would be quicker, even with the engine program they had at that time. Even though everybody and their mother said the 5 speed would be slower. Silly people.
I said that to go here. Who was the LAST PS team to switch to the 5 speed? I know, because I almost got into a fist fight in Seattle a year or so later with the crew chief on the car over it and his idiocy.
Remember yet? It was the stooges at Wayne County and the Dodge Boys. Standing in the pits they said the 4 speed was quicker because they made more TORQUE! I couldn’t believe what I was hearing. I pointed out a PS car is so far above peak torque on gear changes that what little extra torque they made was useless. It was no wonder they had to cheat.
So the crew chief came over and tried to convince me otherwise. I quickly pointed out they hadn’t won **** in awhile and they were going backwards fast. And it turned into a **** show from there.
I’ve laid out more examples than I should have. It shouldn’t take that much.
Believe what you want, but stroke doesn’t make horsepower.
