to stroke or not to stroke?

Mad Sci just didn't address one thing, one very small thing

The added torque of the long arm helps get the car moving faster off the line.
This is why strokers are well liked.

2 engines, displacement the same, HP at the big end the same.
The long arm gets off the line easier and quicker. More torque also equals more HP.

You all are getting carried away. Have a nice day fellas and don't forget to breath deeply before typing. ;)

Some say I'm going fishing, I say I'm going wrenching. ;)


Let me address that right now as you just don't get it.

If your TQ monster stroker king is so good, ditch your transmission and leave in high gear, because the TQ does all the work right? Might as well go direct drive differential as well, you don't need those gears with TQ either do you?


It's just plain STUPID what some people pass off as technology. All you guys who use a head design from the EARLY 1960's, which was developed for 273 CID, with an operating range of 2200-2500 RPM and a redline of maybe, MAYBE 5800 rpm, then add 55-60% MORE displacement, lose rod/stroke ratio and run the RPM's up to day 6500, which is about (roughly) 10% more, and think you are kicking *** are plain fooled. Your transmissions and rear diffs give you away.

So, let me say this about that: If you are hell bent on a stroker here are my guidelines. Take them for what I am charging you for them.

ANY engine designed with production rockers, with MAX porting on the heads and intake (and I mean filler in the heads, welding up the intake and the like) no more than a 3.600 stroke with a 6.250 rod and a max RPM of 6800. Period. If you can use a T/A offset rocker and get the heads and manifold in shape, you can use a 6.123 rod or increase the RPM to a paultry 7200.

Any engine with a W-2 style head would have no more than a 3.800 stroke, a 4.100 bore MINIMUM, big valves, corrected intake. at least a 6.123 rod and about 7500-7800 RPM max. You can certainly go less.

With W-5 stuff you can do about the same, but can easily get to 8200 RPM with the right stuff. If you up the stroke to 4.000 you will need to back the RPM down below 8000. Unless you have a pair and run a tunnel ram. A bigger bore helps.

If you want W-7 info and up, I will give you an address to send cash. Gas, *** or cash, nobody rides for free.

So there you go ramblerod, have I given enough yet? Make sure your bad self ditches all your gear ratios because you have TQ.

God Bless the silly ones.
