motor build up help
383 forged rotating assembly
ms4
ls6 intake
1 7/8 lts and ory
243 heads
how much power would this combo get me? i know it will be more then the 390 i made wit my ms3, 853 heads and 1 3/4 lts. also would anybody reccomend a different cam. id like it big and choppy so i figured the ms4 would be great since i loved my ms3. also what piston size should i go with? i have 93 octane gas in my neighborhood and would like to get it as high as i could thats easy to tune on pump gas.
