Since I had nothing better to do today, I took a good look at the avaliable piston selections, and out of 27 pistons, the KB-107 is the least expensive for your combination at $199.95 set from Summit (I just used Summit to get the piston info and prices.) The Speed Pro ZH116CP is nearly the same as the KB-107 with a slightly lower compression height which would help lower the compression a bit, but they appear to cost almost $100 more ($295.92) than the KB-107.
None of the quench pistons seem to get near the correct compression ratio, besides the KB-104 would be near perfect if you swap on aluminum closed chamber heads in the future.
Using these specifications, here are some results:
KB-107 Piston
Block height 9.60"
Rod length 6.123"
Crank Stroke 3.580"
Cylinder head volume 65cc
Head gasket volume 8.997cc
Air pressure 14.70 psi (sea level)
Launiti Voodo 60404 cam installed per specs (intake opens at 64 degrees after BDC)
The Piston would sit 0.012" below the block deck.
The compression ratio would be 10.18:1
The estimated Cylinder gauge pressure would be about 161 psi (should be good for pump gas.)
So for my
The KB-107 pistons and Voodoo 60404 cam would be my choice, along with some closed chamber Edelbrock heads should make a real strong combination.
I plugged the Info into Dynomation5 simulator, using flow numbers for stock unported heads, and the Edelbrock heads. With either head the low end / mid range torque looks nearly the same up to about 3,000 RPM. The torque curves are pretty broad and flat like you would want in a street car. Here are the HP /TQ numbers
RPM - Stock HP - TQ --Edel HP - TQ
1000 - 68 ---- 359 --- 67 --- 351
1500 - 108 ---- 377 --- 109 --- 380
2000 - 150 ---- 395 --- 143 --- 375
2500 - 197 ---- 415 --- 198 --- 417
3000 - 239 ---- 418 --- 246 --- 431
3500 - 279 ---- 418 --- 293 --- 440
4000 - 307 ---- 404 --- 342 --- 449
4500 - 327 ---- 381 --- 387 --- 451
5000 - 331 ---- 348 --- 417 --- 438
5500 - 320 ---- 306 --- 437 --- 418
6000 - 293 ---- 257 --- 436 --- 382
This was using 750 cfm carb, high flow dual plane intake, and small tube headers with mufflers.
