Can anyone tell me the specs for the LG4 cam? Flow numbers for the heads would be nice, too, if anyone has them.

I know this is an old thread, but I'm curious about the heads flow numbers also. The cam specs are readily available, I just want to know if anyone has flow numbers for the heads. Mine are the 081 castings. I would like to plug these numbers into Desktop Dyno.

Thanks.

Chris,

I thought you had 3.54 gears?

The peanut cam has the following specs:

.350 lift intake and .385 lift exhaust, with a 109 LSA.

Wow, thanks a lot SittingBull! I've read through your port and polish thread many times and I know you have the flow numbers for your ported heads listed, just not the stock flow numbers.

Sitting Bull

No, the ones listed here are just stock LG4 heads. I'll email you the home ported 305 flow file, if you like.
