Ttp!

 

Are these springs good to .600 or .650 lift?

 

.650

We use these springs with our aggressive equalizer cams all the time.

 

what are the two cc sizes offered and what will the larger vs. smaller do? will the cc afect the CR?
Thanks,
SDB

 

Right now all that is available in the 225 heads are 72cc chambers (There will be a 62cc chamber version coming out). However they can be milled to whatever size you like. (.054" gives you 63cc chambers / .030" gives you 66cc chambers). WIth LS1 steel head gaskets 66cc that gives you about 10.22:1 C/R.

Add $100 for flat milling.

But remember you probably will need to flycut because of the size of the valves.
