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?

PAGregSS

iTrader: (10)

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

Bryan@LME

iTrader: (4)

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.

Bryan@LME

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

Bryan@LME

iTrader: (4)

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

Bryan@LME

iTrader: (4)

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,

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..
