LME 6.0L Flow numbers!!
Well, I got a call from Bryan at LME yesterday, and he told me my motor and heads are done! He said the heads came out great!! I would say I have to agree. These heads were flowed on three different flow benches and the numbers were with in 2-3cfm of each bench. Here are the numbers:
Bore: 4.030
intake, exhaust (no pipe)
.200" 136, 114
.300" 206, 168
.400" 266, 209
.450" 286, 223
.500" 304, 231
.550" 321, 237
.600" 335, 240
.650" 341, 243
The cam is a 246/257 .633/.645 114LSA. This head/cam combo on the 408 should be a beast!! This motor will be alot of fun this year. I just need to get cracking to get this thing up and running.

Sounds like a wicked setup. But you'll have to excuse me, to me, getting flow numbers from the same place that worked the heads just seems to me like setting the fox to guard the hens. Or in other words, worthless. Regardless, even if they are 5% off you should have one sick *** ride on your hands.

Great flow numbers. Nice to see you're using a cam to take advantage of the high lift flow numbers. You should fly!

My flow #'s are pretty much the same as yours on 241 casting heads . LME was the shop that did my heads also as well as the short block. LME does awesome work.

I'm not exactly sure what they opened the runners too, I will have to ask. They tried a few new tricks with these heads to see how they would work. I guess they did.

Now I have to convert my DP setup from my LS6 to my LSX intake so I can destroy my T-56!

The Heads are 6.0L castings. They are 2.08" 1.60" valves. The int. runner vol. is 250cc. For 408 inches and a big shot of gas they should do nicley!!
Have fun Ben. Hope to here some track times soon!!

Better #s than a head I had flowed(by a well known operator) a couple of days ago with a simular set up from a well known company. These were 6.0 heads with 2.08/1.60 valves and 232/84cc runners and went 293/214 @ .600 (exh. was with a pipe) on a 3.900 fixture and on a 4.125 fixture went 313/230 @ .600. These heads had the LS6 style ports.

I wouldn't doubt any #'s that come from there. Pecos and Brian really have the ls1 stuff down to an art. They did the engine in my car and it made 564 rwhp and around 520 foot pounds. on pump gas with the timing set at 21 degrees for the n2o. They also did the engine in our race car and ... well see my sig for that.
