Had the Dyno done today at Paragon Engines in Santa Clarita, CA by Auston. Thank you Auston for a fantastic job tuning the Vette and dialing in the cam -

Weather was cool but was humid and drizzling on my way down there.

Edwin and his son Angel did all the installation of the cam and supporting parts here at my home on my lift - thank you Edwin and Angel again for great work.

nice combo that must have good manners; that jump in gearing HAS to make a huge difference


2.56....

madmatt9471

Thank you very much and it does have great manners and the 3.42 and Yank SS3200 stall all comes together to make an awesome combo -

Man I really hated the 2.56 gears so much it wasn't even funny -

Thanks,Matt
