Hell, just shift when the valves float. That's the best chip there is.

Nice Stroker, your a laugh a minute...... on that note.. you could wait till the rods come out the side of the block and then back off about 1000 rpms.
but seriously you won't know till you try. all the combos people have been saying above are all good answers.
 
1st=6300-6500
2nd=6800-6900
3rd=6800-7000'ish
4th= I have buzzed to about 7000'ish, but trap out at 59-6200rpm

.030 kb 340, stock rods w/arp, MP.528 284* 112 ,894 x flow mild port 242cfm, 750 holley, 3.73, 25''. something tires

1st=6400-6600
2nd=6800
3rd=can't remember, it was unsafe to look down at the tack cause the car felt like a rock skipping across the water...


.040 kb 410 , h beams, 915 J full port flowing over 275 cfm, .564 lift 284* 110, 750 holley, 3.73 25''. something tires.
 
Those freekin cats are creeping me out! lol


W5 heads, .672/277 solid flat tappet, 8000 with the 340 and 7200 with the 360.

Single 4 on the 340 950 cfm and same carb on the 360 or the new TR set up with 2 750's.

yes it is,just imagine if the enginers would have put alitle more effort into getting the lifterposition and angle correct instead of keeping the old Poly patern.
 
360 +0.030 with KB107s, MP purple 284/484 purple cam, ported magnum heads, Found out I was shifting at over 7000 rpm with no tach, HOOked a tach up and set light to 6500 and it still pulled hard after the light kicked on. Happened to spin rod bearing a day later. So it's comin out this weekend!
 
410 stroker, 248/254 duration solid roller, stage II ported Eddys, I shift ~6200. I’ve tried shifting 6000-6800, but the ET was the same so I try to keep the RPM’s down (easier on the motor).
 
Oh, we revived this, eh? If you really want the "real deal," here's this:

I've been shifting at 6300 but I'm going to drop to 6000 - maybe 5800 on the 2/3 and see what happens.
 
I find it interesting that some give only one number......

Every gear should be different, in the case of gasoline engines, higher in the lower gears.
 
actually...you will find out sometimes short shifting 1st gear will get ya a quicker ET...

True, I guess, I got better ET's by starting in second too before.... I guess it depends on ratio and t raction. If your hooked or not makes the difference, eh?

I've played with shift points in 100rpm increments. My combo likes 5500rpm for the 1-2 and 2-3 shift. It runs it's quickest there and is consistent as can be.
