With respect to jakeshoe, the B&M kit is only $29 and turns a 90 minute job into a 30 minute job. Having done this modification a few times, if you tell me what RPM you want to shift at, I can just about tell you what weights to use from the kit.

6500

The #3 and #4 give you 56-5800, the #4 and #5 give 6000 or a little higher, so probably the #5 and #6 would get pretty close.

OK,
So my method costs 1/30th as much

The advantage of the kit is it does include springs , gaskets, and the little "axles" instead of using nails, however I would lose the clips anyway, so the nails work better for me.

I have an assortment of springs that I sometimes play with, but usually I just take weight off until I get it where I want it.

It doesn't take me that long to grind the weights, and I have a pretty good idea how much to go so it's not a 90 minute job for me.

6500 rpm shifts will need the secondary weights cut down about as much as you can go.

I'm not as experienced as you obviously, so all the trips to the store for nails & gaskets are a fair trade for the $29 to me

Any advice on where I should be shifting with this cam and stock bottom end? Does 5500 sound about right?

5500 seems pretty close, but 234@.050 is a fairly big cam for a small block, and you have the 200cc heads, you might pick up a little by shifting at 5800 or so. My 350 has a completely stock bottom end (stock oil pan, stock oil pump, stock pickup, 1976 2-bolt block, original cast crank, original 1976 nothing-special rods, all with stock fasteners) and I've got a couple hundred drag passes shifting at 5600-5800 with no problems.

that is definatly a cool mod and the price is certainly right, but, why wouldnt you want to shift manually at the track?...wouldnt you then be able to take full advantage of whatever rpm your car works best at?...did i miss something?

If the driver manually shifts at 5800, or you leave it in Drive and program the governor to shift at 5800, what's the difference?

Just ordered the B&M kit last night, on my doorstep at 10 this morning, now that's SERVICE!!!!:thumbsup: Took 2 tries but ended up with the 4 and 5 weights with the yellow spring, 1-2 shift is 55-5600 and it shifts later when just cruising also, much better than before. Have to find a little more road to check the 2-3 shift. This should make racing MUCH easier. Thanks Mike (Georgia69)

Glad to help, let us know how it goes at the track!
