Lots of buzz words regarding lobes these days. Talk to Mike, you may be shocked he's been doing lobes like mentioned for years.
you’re right that’s what I’m running a asymmetrical inverse radius cam .comp cam is advertising it as a low shock cam.i would say that they are both on the same page as far as cam design.i just looking to see what other people were using with a MSD standard length runner and a head that flow 400 cfm @700 lift .thank for your input (and I know that one of my problems was running out of fuel 42 lbs injectors and running out of fuel pressure with a standard C6 stock fuel pump.i now have 60lbs and a 525 Walbro in the tank)
with a ported intake and the right cam on E85 @12.2.1 I see no reason not to make at least 650 rwhp on a roller NA(thru 3.90s
If you haven't yet, show Mike your dyno graphs with and without n2o. Let him know your upgrades and goals and ask what he would do if it was his combo.
I talked to Mike Friday and he told me to ship the cam back to him.he said he would take a look at it and see what he can do. I’m going to go ahead and pronounce it dead. I’m just looking around to see what people are running max street and strip in 430to450 cu inch. thanks for your input
i have a lsx454 solid roller, 12.3:1 e85 running a cammotion llsr 255/269 Duration @.050’’ 114.5+4.5. 702’’/.684’’ 673rwhp
WOW that some healthy numbers what intake are you running?that the kind input I’m looking for
i decided to follow your lead and ordered the same cam they recommended 259/266 113+3 704/704 lift but were I was running nitrous I decided to widen the lsa a little bit.thank for the cam spec. I’m still going to send my old cam back to Mike Jones to see if he can regrind it. Thanks for your input
440 LS7, 256/270 solid roller at .747 lift, mamo heads, YT rockers, 12.7:1 compression, etc, etc, etc. Smooths out around 1500 rpm in 6th. Red pull was radials, blue pull was bias ply
Thank you guys for the info I just took a new set of morel lifter 6177 to the machine shop today .hopefully they will have the block cleaned up in a few weeks .they are going to have to rehone my cylinder wall .I might have to send my pistons to line2line to have recoated.
anyway I’m going to copy and paste what you guys are doing.I’m thinking 250s/260s duration @ around 700 lift . thank you guys for the feedback
Definitely some great performing setups posted in here, got a link to that video Last1?
I’m sorry when it comes to this computer stuff I’m no good at it. he posted the second part on camshafts on YouTube a couple days ago.maybe somebody on here can post them.i wish i could help. I sended the lifters back last week I still haven’t heard back from them.it wasn’t bore issues it was the roll pin walking out of the lifters.
I just typed in his name and 5 videos came up with him. He has a cylinder head flow one that was also good. On the cylinder head one the most interesting thing was he said the 1 inch lift flow is still important even though you may only have a .620 lift cam. The reason being is that what is going on in cylinder head is much more pronounced that a flow bench and that what you want to look at is the .400, .600 and 1 inch lifts (this maybe a little different for smaller cams) and to look at the .600 to 1 inch lift delta and make sure it is still going up though it may not be a lot up between .600 and 1 inch. For example you might have a ported LS7 head that flows 380 cfm at .600 and 400 cfm at 1 inch versus the stock GM head which could be say 350 cfm at 600 but only 320 cfm at 1 inch (that is what you don't want even though you have a .600 lift cam). You will notice on a lot of the ported GM LS7 heads there is not a lot of difference in OEM head between say .100 to .500 lift (some are even worse the WCCH flow charts on the website are pretty good demonstration) but after 600 they really flow much more and yet the guy picks up 30 hp and he only has a 600 lift cam. He also said same concept goes for exhaust try for no fall off in flow.
Weingartner has some good info on heads. I think the big trick is NOT to hog out too much, so that flow velocity is maintained, yet do enough to keep flow going at those higher lifts. Truly a high wire act....

decided to run the same cam your running because of running nitrous.the cam that cam motion spec for me was 259/266 113+3 704/704 lift.
were I’m running nitrous I decided to go with the wider lsa also to help on valve clearance.
