Aluminum Block growth. QUESTIONS.

I have ran a iron block for the past 19 yrs, 2010 is my first go around with a aluminum block. How much more deck growth will this thing see? We had some tight clearance on the exhaust valves in 2009 and were gonna take about 15 out of the pocket, but... Since now I have an aluminum block just curious how much this thing will grow and what my quench and piston to valve clearances will be effected now.
Thanks
Jim

around .010 it will grow..Dave
example..if you set your valves @ .016 cold.. set them hot @ .026

 

Valve setting hot

.010 growth is what we see also between cold and hot valve settings on a all alum motor

good luck

What kind of combos are you guys getting .010 change from hot to cold on? On the brad 5 we ran in our top alky hydro I set the valves by feel cold, just when I could feel it wasn't 0 it was set. hot it was a perfect .026. I know a little primative but it worked. but on a 481x olds the .012 cold gives us a hot .024.

 

Solid KB Olds and AJ Billet Heads. Lash .014 cold to get .026 hot.

 

Solid KB-5, wedge, water in heads, cold .012 hot .022-.024.

 

New centrey 10.200 solid block, Dart 360 heads, cold .010 intake .012 ex, hot after a run, .020 intake and .022 ex.
