deckheight Posted May 21, 2009 Report Posted May 21, 2009 If I remember correctly re-chembered it also. Pretty sure you would not be happy with taking off .030" without doing something with the squish band. Probably should get a hold of Mopar for the details before going any further. Quote
dusty_v141 Posted May 21, 2009 Author Report Posted May 21, 2009 MOPAR whats your opion on this and can you explaine the squish band too me please Quote
dusty_v141 Posted May 21, 2009 Author Report Posted May 21, 2009 ok what does the squish band do Quote
BellicoseBanshee Posted May 21, 2009 Report Posted May 21, 2009 The squish band does two things: It squishes the fuel/air mixture away from the edge of the cylinder towards the spark plug. It also helps mix the fuel and air more thoroughly, and it helps mix the residual exhaust gas with the fresh charge. Quote
kswayze Posted May 21, 2009 Report Posted May 21, 2009 Not really trying to hijack the thread but who are some of the builders that do a good job at head work? I cannot find any locally (Oregon). Quote
deckheight Posted May 22, 2009 Report Posted May 22, 2009 LOL! Shoot me a private w/e-mail and what you want to do as far as octane requirements. A properly re-designed OEM head is no problem for 92 octane compression. 100 octane compression is also no problem, but requires tig welding. 110 octane type compresssons are not possible with an OEM head. The above assumes head geometry is designed for a 54mm stroke and an acceptable MSV for the octane fuel.

blowit Posted May 22, 2009 Report Posted May 22, 2009 (edited) Here is one of our heads. We have been doing head mods for 10 yrs. Will admit that we are running behind this time of year though. Brandon Edited May 22, 2009 by blowit Quote
BellicoseBanshee Posted May 22, 2009 Report Posted May 22, 2009 That is some nice work Brandon. :thumbsup: Quote
blowit Posted May 22, 2009 Report Posted May 22, 2009 That is some nice work Brandon. :thumbsup: Thank you. I drew the line years ago when I took a head to machine shop to have it "shaved" and it looked like lunch meat that was cut with a claw hammer. We have us some new hotness that should be coming out in the next month. Stay tuned.... B Quote
mopar1rules Posted May 23, 2009 Report Posted May 23, 2009 brandon, you use mastercam to create the program for you to cut those little grooves? you use a little 1/16" ball endmill? looks like excellent machining. Quote
