UDHarold Dec 13th, 03, 2:15 PM Chris, I'm getting old, and that was from memory. The 81° BBDC 35° ATDC is correct. As far as valve lash is concerned, anywhere from.020" to .034" is OK, but the lash ramp is .01734" high, and that's .030"..... The tighter lash is to make it less explosive on the bottom-end.... UDHarold THORSS70 Dec 13th, 03, 3:35 PM Harold, on that note I could increase the lash on the 427 to boost the low/mid torque? (I am at .025 right now) Not that I really need it but can't hurt to try I guess smile.gif Chris, you ever tried going to .030?

Stay tuned THORSS70 Dec 14th, 03, 8:49 PM 4500 stall? Yikes, hold on for your life :cool: I picked up a set of Edelbrock no-hop bars this afternoon (thanks Alan) and if I have time after the install I will throw a .030 lash on the cam and see what that gives me smile.gif THORSS70 Dec 14th, 03, 8:51 PM Jeff, I found my original cam card that was sent with my cam today, do you need it? I will gladly make a copy and send it up smile.gif JWA Dec 15th, 03, 1:15 AM That would be great Craig! An email copy would be fine. :cool: THORSS70 Dec 15th, 03, 11:06 AM Jeff, you got I will get it to you asap. I will post back on how I will send it to you. Cable Dec 15th, 03, 1:57 PM I am guessing by this post that you received everything okay, except the cam card? I thought it was inside the cam box. Hmmm... THORSS70 Dec 17th, 03, 5:26 AM Jeff, sorry the home computer went down, I am at work and will e-mail you this morning. | ||
