Are these really the RAISED RUNNER or the LT4 raised port?

I thought only a custom intake would work with the RAISED RUNNER head.

 

Very nice numbers. You mentioned at LS1tech that you are going to put a direct port setup on there as well, that thing is going to be a monster.

 

There is a Super Victor intake that will work with them..... that's what they used here. Larry Meaux does some killer work, good to see those numbers with that and that big ole cam!

Just to make it clear, this is not my motor. Im just reposting it for those that havent seen it.

 

Ah, I was not aware of that intake. Thanks.

 

damn nice numbers, what are you gonna do to try to hit the 700 mark?

 

So like what would the duration numbers be on that cam @50 ??

Steve

 

That IS at .050"

 

Thats a big cam.

Steve

 

I wonder what the reason is/was for building a "pump gas" motor with that size solid roller cam? It's not like it's going to be seeing a lot of street duty or anything

 

The reason----

To make power in the mid and upper range.

 

Really Nice #'s!!

 

I wonder what the stall point of those heads are...lol They were increasing in flow even to .800 lift !!!

 

I've seen some ls1 heads from Larry Meaux that never fell off and we flowed to 1 inch lift.
