408's make Power My response is directed to the post by "techLs1" claiming Futral is lying about power numbers. If you want to make BIG power, get out your checkbook and call FUTRAL - otherwise refrain from posts which provide no value.
My old 408 made 552 at the tire with a FAST 92 intake. This was with 4800 stall and T-400 and Dana 60 rear. Dyno sheet attached. Allan Futral knows how to make big power - PERIOD. It is not cheap to do, but they have the secret sauce.
By the way, attached is my dyno sheet on the 415ci that made 614 at the tire. Again this was through a Neal Chance 5400 Stall, T-400 Transmission and a Dana 60 rear.

Some people always wanna make that claim that Futral is messing with the dyno or other nonsense but the fact is Allan knows his ****. That's why we call him the LS Whisperer down here.

Well, if you need to get out your parents checkbook to have your car worked on have at it. I'm just saying the numbers seem high and not realistic. I don't doubt that they are fine mechanics and know what they are doing, but for the given combo's they seem a little inflated. So Im saying post up your 1/4 times and let's see if those numbers are accurate. If they are real there should be nothing to hide. I could be wrong but would love to have someone explain how those high numbers are accurate other then just saying "X" shop rules. I welcome for someone to explain the engineering behind the science of those numbers vs. web-hype.
1/4 mile isn't always the determining factor because not everyone wants to maximize their suspension for great et's. My trans am made 640/580 and ran a 10.9 @ 132 with a measly 1.8 60'. It had ccw's on it with lowering springs and a handling suspension. If I was interested in maximizing my power I could have put drag suspension and slicks and skinnies on it but that didn't interest me all that much. I wanted big power but to not be one dimensional.

The original poster is very proud of the build and from my experience with Futral Motorsports, both parties should be very happy with the results. We are happy to have you at the site, but your baseless comments should be kept to yourself.

520 is very possible! thats only 605-610hp at the Flywheel in an M6 vette and a 364cid engine with 350+cfm heads should easily be able to do this built right with the supporting hardware!
No two combinations are the same and usually its the good shops that set the Standards that everyone else shoots for
I say Congrats Thats a Awesome Build! if you don't have anything positive to add keep it to yourself and Go build some Power for yourself That will keep ya busy

What is this with the parents check book?? I'm not a kid, I have a dynojet dyno for four wheelers. The only difference between mine n Allan's is the wheel. It's the same n the four wheeler world when I come out n beat someone with alot less motor they wine n cry saying I'm lying. If u don't believe us then put up some money and we will take the motor apart for u, if not move along and get ur parents to buy u something better. Maybe like a beige Volvo!

yes but that 408 was at 14-1 compression on race gas. Not really a street motor. most 408 are in the 480-510whp range so yes 520 out of a stock bottom end ls2 is not the norm. especially with ported ls3 heads and a ported stock intake. I can see were that seems a bit high. Had is been worked TFS 225's with a ported fast 102/102 at 11.8-1 compression with a big cam then I can see those numbers happening.
But Dyno numbers can be different dyno to dyno. So if the car goes out and runs 130+ it's making some good power.

My old stock bottom end motor that Allen built went 10.90@123mph N/A fullweight and with stock suspension..
