Last November I pulled my MTI 427 LS1 and sent it to Futral Motorsports in Walker, LA.

My engine was using WAY too much oil and just didn't feel as strong as it did. I didn't want any more worries of block integrity, cooling issues, etc.

Allan received my complete longblock and disassembled it. He said the block was in good shape, none of the liners were dropped, cracked, etc however he did think it was using some coolant at the base of the cylinder. I sold the block with this info provided on E-bay (well a buyer offered me a great deal on the item on E-bay so I sold it before the auction ended) and the pistons were sold together with it.

Now, on to what I had done.

GM 6.0L LS1 Iron block bored 0.060" over w/sonic testing and it passed w/flying colors, decked, align honed, deburred, etc.

Meaux Racing reworked my MTI SIII LS6 heads and picked up a HUGE amount of CFM at every lift point.

Custom Futral Cam Motion camshaft - 246/250 .633"/.628" 112
Static Compression Rato - 11.72:1
4.060" Diamond Pistons/rings
Cometic MLS headgaskets
Added ARP main studs
Swapped over my 4.000" Lunati crank and 6.125" Lunati Pro Billet Rods
Jessel 1.7 rockers swapped over
TR shimmed oil pump swapped over
MTI pushrods swapped over
Custom Dual Valve Springs - K-Motion

Allan went above and beyond all of my expectations. He gave me all the info I asked for, even after probably over 100 PMs, numerous phone calls and various e-mails. He and Candy tolerated and appreciated my every question and request. Their establishment, hands down, is the best I have ever dealt with.

Now, onto the engine. It burns ZERO oil, coolant temps stay at 180*F or less in 100+*F stop and go traffic, runs on pump gas w/no issues. It's very docile until you go WOT. It never stops pulling. I have a grin from ear to ear everytime I roll into it. It's got so much torque I don't know what to do with it.

I put just over 1000 miles on it, changed the oil and took it to our local dyno, a SuperFlow Dyno. It has correction factors for a Dyno Jet that have proved to be EXTREMELY accurate based on quite a few people I know that have dyno'd on the SF and then went to a DJ w/the same mods, and the corrected DJ #s from the SF are within 3-8 RWHP of the DJ.

Here's what the setup did w/no WOT tuning:

SF #s 470 RWHP 460 RWTQ, FWHP 552
DJ Corrected #s 498 RWHP 470 RWTQm, FWHP 585
After dyno WOT tuning:

SR #s 501 RWHP 485 RWTQ, FWHP 589
DJ #s 530 RWHP 515 RWTQ, FWHP 624
Graph:








Here's the DJ Corrected Graph:







This was all with a stock MAF, 25-27* timing, stock LS6 intake, 3.42 gears in a 10 bolt, 12.8 A/F, through cutout, pump gas, no dyno tricks, tire pressure at 32 PSI. This put down right at what Vince's FMS 408 did which is an almost identical setup in that I have LS6 heads and he had 6.0L heads. I run Dynatech 1 3/4 to 1 7/8 headers, to a 3" ORY to a 3.5" cutout. Stock water pump, ASP pulley, 75MM lid.

The shop was able to overlay my graph with a 96 GTS Viper with all bolt-ons, rocker arms, pulleys, TBs, headers, blah blah with my graph:





I'm very pleased with the results. They're exactly what I anticipated based on what FMS has done with similar combos in the past.

I'll get it to a DJ later on to see how the two compare (DJ corrected vs DJ actual). There are no DJ's really close by, anyway, else I would have done it that way.

Thanks again to Futral Motorsports, Allan and Candy are the bomb!

Thanks to my brother, Alex, for the dyno tune
This car is an absolute MONSTER.

 

Congrats man! That just gets me more pumped to finally get my car back from them. 1+ year so far, but its definately gonna be worth it. Im hoping they will finish it up within the next week or two at most, but I dunno, they are very very busy....

 

great numbers and hats off to Futral.... especially with an LS6 intake on it.

Static Compression Rato - 11.72:1

I assume you run 93 octane (not spiked at all?).

Is that cam a hydraulic type?

 

Put a LSX/90 and a 85 MAF/LID on the engine next and I bet u see at least 25RW improvement......Awesome results,Congrats and good luck w/her.....

 

we're taking that fr to BG next weekend. you will deffintly have to take me a ride. i still got you on the numbers though, wahaha. congrats i bet it sounds mean on that dyno

 

Just looking at the dyno sheet makes me grin...

 

Sounds like a nice setup Levi

 

gnX7, this was 93 octane pump gas right out of the Kroger pumps and yes it's a hydraulic roller.


The TQ curve is just awesome.

 

Nice numbers man.

 

WOW!!!! Talking about being consistent.. FMS Rocks!!! Congrats Levi!! It must be nice to have a FMS414ci

 

It's probably all in the MAF. Congrats....

 

Nice number's Levi.

 

Very nice, Futural seems to put together some great engines...

You know, this is the second time I have heard of an MTI shortblock being shady....

 

FMS Rocks!!!

 

Not to high jack the thread, but hows your car running? Its nice to get an update from someone that has had a motor built by the same company i am, just to make sure everything is still running fine and dandy.

 

Just curious, what did it run you? Sounds like a good set-up! And dam good numbers!

 

Does the car still have a 12 bolt with 4:10's, or a stock rearend???? Was this with a open cut out, or through exhaust?????

 

Congrats Levi!!!!

 

Nice numbers!

Do you happen to know the .006" lift numbers on that cam?

 

stock rear, the 12 bolt had to go. probably through a cut out, not sure on that one
