had 268/280 224/230 .477/.480....thinkin about bumpin up to 274/286 230/236 .480/.491. comp cams. any advantage here? 340 six pak approx 9.5 to 1 compression.




you would notice a slight hp increase with that cam. However, i doubt it would be worth the money (and labour)for the increase in power over the 268. like maybe 15hp?? i would recommend spending the money on something else.
I used to run the comp 268 cam in my 340, i had iron heads, 10:1cr headers etc. I decided on the cam change (285HL, like i previously mentioned) but also went with edelbrock heads. power increase was substantial. but looking back, it was probably mostly due to the heads.
