TTT for today

 

the 454 is my dream

 

Will you sponsor me? Id personally go and pic up the 454 tomorrow No shipping!

TTT For a great company!

 

Great company to work with, Bryan knows the meaning of customer service. For the money the shortblock is amazing. My tuner looked at the invoice and was flabbergasted that they could sell it for that, knowing that LME is a quality shop.

I must have called Bryan 100 times with stupid questions and concerns and he was always friendly and patient with me.

looking to go with a 454.... how would that work with boost?

 

I'm curious about something, what is the weight difference between the 454 LSX shortblock and the LS7 shortblock?

 

This would not be a boost friendly shortblock. If you want to do a low compression 454" we can have some other custom pistons made to lower the compression. The price wil be the same as the above.

 

The weight difference is aprox. 150lbs

 

I believe that L92 heads would bolt up to the 454 LSX short block.

What style head would I use on the 440 LS7? Would an L92 head bolt up here also? Or does it have to be an LS7 head?

This might be a stupid question, but I am not familar with the interchangability of these 4th gen engines.

 

You would want the LS7 heads. Here are pictures of LME's LS7 heads ported Last LS7 they did made 575 rwhp NA

 

The L92 will bolt right up to the 454" LSX and the LS7 440"

LME is currently building a 454" LSX with unported L92 heads. It will be interesting to see the results with big cubic inches and a unported cylinder head.

 

454" LSX is sold.

440" LS7 is still available.

Thanks for the inquires.

 

I predict a boatload of low end torque, and very low HP, should make a killer stop-light to stop-light.

Bryan, since you're able to substitute a custom low comp piston for boost on the 454, could you also add 1 more cubic inch so I could call it a Pontiac

Killer price on the 454 shortblock, we will be ordering one very soon,
Ed

 

Yes we can add on more cubic inch for ya!!

We look forward to doing business. Give me a call when you are ready.

Thanks,
Bryan

 

The 440" LS7 is still available. LME can set up this shortblock with any type of cylinder heads is needed.

Thanks,
Bryan

What would be the cost of the LS7 with a 4" stroke?

I need this for NA street and longevity so I am concerned about a 4.1" stroke and piston wear/slap etc..

 

Bryan,

A photo update.....











It has an ADM PERFORMANCE CNCed L92 top end kit with a custom grind with 240ish and .670ish on a 114.....should make your motor REAL HAPPY.....

i'll post up future updates with a graph and time slip and thanks again for all your help brother.....

you guys keep up the good work and the WARHAWK block looks crazy bro......i think Pat (Quality Motorsports) was saying he had one coming for a customer....can't wait to see that monster.....

Pat

 

nice to talk to you again bryan.....

here's the dyno brother.....this motor is gonna be a blast.....keep up the good work brother!!!!!!!!!!!

motor on 26 degrees with about 97 octane and 100 shot with a nitro dave truck plate......

 

Would the 440 ls7 be better suited as a NA streetable motor?.......how would it do with nitrous?
