The new Summit Racing catolog has new 195cc Trickflow LT1 heads.

Yes kids I said LT1 heads.

 

Looks intriguing. The did some LT1 heads years ago in VERY low quantity. Anyone know details on those? I would assume these would be similiar.

 

Here's some more details for u guys:

The ford heads typically don't outflow the competitors (for exception of the trickflow R head) however they still put down some good numbers... can't wait to see how these do...

Has anybody ever got flow numbers for the edelbrock heads?

 

What is the intake runner size on the factory heads?

I wonder if these can be hogged out a bit more than the GM heads.

 

170cc is stock intake size and i believe the combustion chamber is either 56 or 58cc
i'm sure those heads will be able to handle a good amount of work, probably very comparable to the LT4's if not better!

 

Woah.....someone putting out a new part for our "archaic" LT1??

Sweet!!!! Gotta get some numbers on those.

 

I fired off an email to TrickFlow looking for flow numbers. You know they have some. If they don't want to release them you know the head is probably only good for a boat anchor.

 

The website says these heads are good for blown or nitrous cars so maybe they have a thick deck like the AFR heads??

They seem very intriging, flow wise because stock is 170cc and these are 195cc.

 

There is another thread that some guy knows someone who is flow testing them or trying them out, or something. Can't find the thread right now though.

 

there is just about no information about these heads on the internet . someone find something !!!
