Before I start this thread I want everyone to know this motor is not for everyone, some will say its not worth the money and some will say it can built in their garage for less. These ppl truly don't know what it cost to make this kind of horsepower!

When I was building this motor I originally wanted the highest horsepower N/A motor I could still drive anywhere on the street. Which is exactly what Tony gave me. The plans have changed drastically with the car and I've went to a solid roller lsx 427.

If you click the link there are a tons of pics of the motor, unassembled and assembled. I put the motor in Camaro and it made 667hp and I'll have to dig out the tq. That is to the tire, through a m6 and fab 9. All these numbers that are shown the car was on e85, and probably could have been run on 91, with a less aggressive tune. I took the car to the track and ran 11.19 @132mph with a 2.10 60ft. That was no two step, line lock nothing, just me saying here I go. It also ran 163.8 mph at shift sector at coalinga airport. My car weighs 3400 flat without me in it, so maybe 3560lb race weight. Now to the specs of the motor.

454 CID shortblock consisting of the following
Darton sleeved LS2 block with internal oil passages ported
Lunati 4340 non twist forging crank with 2" rod journals
Callies Compstar H-Beam rods with 2" journals and ARP 2000 bolts
Wiseco lightweight custom pistons with .043 rings (Total seal), gas ported and skirt coated as well
Melling high volume pump (ported as well)
Comp Cam 251/265 on a 113 + 2
ATI Harmonic balancer hybrid design (steel hub and aluminum shell) FBody offset / 10% Underdrive
FBody pan fitted with Improved Racing internal sump baffle
Johnson Short travel with axle oiling HR lifters

Engine Top end
MMS 265 LS7 heads CNC ported and hand finished chambers, bowls and short turns (also upgrade full hand finished exhaust), hollow stem stainless intake valves, lightweight solid stem exhaust valves, PAC 1207 springs and PAC Ti retainers. Milled to achieve 12.75 to 1 CR (E85 or Race gas application)

Yella Terra Ultralite rockers 1.8 ratio P/N 6754
Manton custom length pushrods 3/8 diameter X .095 wall thickness
Rollmaster single roller timing chain set "Red series" with higher quality JWIS chain and OEM LS2 style chain dampener
MSD LS7 intake ported and optimized for MMS 265 heads / Stealth upgrade performed to the cover (logos removed), new LS7 fuel rail installed with customer supplied ID1000 injectors

Now on to the price. I paid 25K for the motor and the intake. I think added all my covers and throttle body. Which is still all on the motor. I would like to sell this as a complete motor, intake to pan. That means everything, intake, throttle body, injectors, wiring harness, fbody 411 m6 ecu. All you would really need to do is add accessories, and install it into a 4th gen. If you are interested in buying it without the intake, rails, and injectors. We can figure out a price. I have 1500-2000 miles on this setup. I know I'm not going to recoup all of my money invested into the motor, but I am not disparate to sell it. I have no problem leaving it storage, and putting it my 69 camaro when I'm ready.

Asking price 20k

I think just a quick google search of those Manton Rods should give a good idea of how much these build cost lol!

Free bump! GLWS bro! New mayhem on the street videos coming soon?

Fixed the link...

thank you, I know most guys here need a dry sump motor. But even swapping this to a dry sump set up would be cheaper than building a whole new motor

I’ve got one just like it, but a 434. Great price here especially considering the harness/ECM and ALREADY TUNED!!!

Is it over-square or is it a longer stroke ? What a great/typical well thought out MMS build. How was that cam on the street ? Similar build in the works and yup its pricey dropping one in is a good play. Bump.
