Default Re: Camshafts almost done

If it was me, I would have had to order about 40 of those custom retainers, because some would get dropped, some would get launched into the far reaches the garage after ricocheting off the ceiling and walls, the dog might swallow one, etc........Just talking from experience.

What is the compression ratio you are going with?

I am finishing here a 427 and go with a 13.2 : 1 ratio with Stage 3 cams and 40/36 mm valves.

I want to run pump gas without pushing the head gaskets out. E85 with 13+ compression might be interesting.

Degreed the cams yesterday. As everyone says... the first one took about 3 hours, mostly because we couldn't get a reliable measurement on the darn thing. After that, things got faster and we mounted the dial indicator differently.

Ended up making the small adjustments by moving the cams to the right lift at the specified .050 opening point. Took an average of 6 readings (.020, .050, .200, opening side and closing side) to verify the centerline. Got all but one to less than a degree from spec. The LH intake cam is 1 degree retarded. Close enough for me!

Only wasted one $16 bolt on the first one we set. It moved three degrees out when we torqued it.

Dyno session set for week of 17 Jan.

P.S. Sam, how did your motor turn out?

Cant wait to hear some dyno #'s.

Hope to have mine in Jim's car this spring and get some final tuning and #'s on it.

Todd,can't wait to hear & see that monster run.

A long wait but well worth it,you'll forget all about the work and money you put in her the first time you hit 7500.

Happy New Year

Just noticed my cams appear on the bottom right of this page:
http://integralcams.com/custom_cams.htm

Truly a one-of-a-kind now. Steve has sold the business recently. What a bummer, he was very good to work with and we might have had a long-term supplier of new LT5 cams. They performed flawlessly on my 427.
