Guy has a 427 he asks about a top end for 650. Ls3 or ls7 heads. You said as well as others go with a aftermarket ls7 head = $3k no way around this cost...Seen as Fact. Factory ls7 heads are a no go with valve guides. What's left Ls3 and a aftermarket head isn't all that much better still around 3k. 🤔 hell a Cathedral head could probably do 650 with a ls7 size (427) as they had cubes before the ls7 heads. You mutha fuckers are something else with the BS about you gotta have this or that and people have done more with less yrs before you and the same idiots. Guy says he could get ported ls6 heads just from me saying a 427 could make 650 and the guy says he could get a pair.
I used Cathedral heads as a reference to show it can make hp any person with Half a brain would Know that @ 618 fwhp using a 408 going to a 427 would net 10 fwhp just because of Surface area of the pistons. But it would be more than 10. So now we're around 635 fwhp add 3 to 4 degrees in cam duration throw in a vacuum pump. There's your 650 with a 427 again using common sense from who everyone knows has a Honest dyno, being Westech. You guys are so full of shit it's ridiculous. Reasons most these same mutha fuckers won't come to YB... what I said was basic shit that doesn't Depend on a brand nor name its fucken common sense. This is what they call this Site
Ls1sales.com Then mutha fuckers don't know the formula nor do they get basic shit like going up on piston size nets what % in hp if everything stays the same. What I showed using a 408.
I'm here for one reason to kill all the Bullshit about Hp and what's needed. You mutha fuckers may have built a engine but the same people don't know a mutha fucking thing about the what it takes to make hp ...you'll throw money at it and try to learn. I hate idiots that got money & Still a idiot who can build a engine. I've built engines, homes, Apache helicopter stuff as well as the Human anatomy. And we're talking Hp and you've worked with some Nascar guys or group... your over here for a reason not the real engine builders sites
I post something on YB and or Speedtalk with Professional builders & builds and what's posted is seen as Fact before or after the fact of... I look to kill the avg enthusiast and Bullshit. You call it messing up a thread I call it you maybe correct but if a factory Cathedral head is a option you can use it and get a better Cathedral port later and still have the same 650 till you get the better head. Oh no you gotta have a 3000.oo head. Really, lol I'm calling bs for what it is.
He may have needed the $10k package for 650fwhp
I'm with you but...DM just sell you LS stuff and come to the dark side and be satisfied, lol, .
