never said you were. nor did i imply it. i just asked what bore/ stroke/ rod those pistons called for. and if they are not for a 4.030 bore/ 4.100 stroke/ 6.098 stock rod than they wont work with what you want to do. and if you wanted to build a 370 im guessing those are for a 4.030 bore/ stock stroke/ 6.125 rod motor. if they are for stock stroke and rods but 4.030 bore than that would be a 369ci. and also if your using a stock deck GM 6.0 block i would stay 4" stroke or less.

Yea 4.030 stock rod and stroke thanks for that info were did the extra cube go how is it a 369 Cid and not a 370 Cid?

the rod size since the rod you use for a 370 build is a 6.125 aftermarket forged rod. 369 ci is a stock 6.098 rod. i would say its basically the same motor.

OK how would I make up power w/ the 317's if I don't run the l92's and with the stock rods forged pistons can I shoot a 200-250 shot

I dont believe rod length makes a differance in displacement. Just bore and stroke. Eric L
