L78/L71/L72/LS6 143 "blueprint" camshaft - Part 2

[1969z280]

The cam has good idle quality and pulls like a $#@@%$! It really lights up after 4,500 RPM!

I just got my L72 Original Paint Corvette back together with the help of your camshaft. It runs like a bear and I'm still breaking in the motor and working through dialing in the carburetor. Thanks for all of your help, Ed

SWEET! The '66 L72 combo is the nastiest of the bunch...

We wound up installing it six degrees retarded as you suggested. My original plan was to build the engine "bone stock" but, I decided to shelf the 7115 crank and original rods and went with really nice pieces from Eagle. I also upped the compression with Ross .030 over pistons to about 11.6:1 The rotating assembly was balanced and we did a little pocket porting on the heads and triple cut the valves. I'm stuck runing 110 Sunoco but she's a real wolf! Thanks again, Ed

I gotta agree about that '66 L-72 being nasty! I've always thought of them as one of the most over-powered, under-tired Musclecars of all time! Brutally fast! You line this '66 up against a '67 427-435 Tri-carbed 'Vette and my money would be on the '66 car.

Too cool! Another car that rockets like it should. Congratulations guys.

I agree about the "skinny tires". I'm running F70x15 Coker redlines on a 15x6 steel wheel with the original hubcaps. I've got a set of old American D-spokes that I'll be mounting up this week. Now since it hasn't rained today (first in two weeks), I'm off to continue the break-in! Thanks, Ed

The original cams were ground 6 degrees advanced, as are the true blueprint copies...so retarding the cam 6 degrees basically puts it back to "straight up", and brings it inline with where the compression maps say it needs to be.

Ok, our hard drive went out with my cam info, so I wanna make sure I've got everything correct before I submit our order:

Alan Kempel - 2 cams
Joe Warren - 1 cam + 1 edm
Mike Angelo - 1 cam
Alan Forman - 2 cams + 2 edms
Tim Clary - 1 cam + 1 edm
Jim Lerum - 2 cams + 1 edm
Rus Sharin -

Everything look right?

BTW: I need phone #s for Mike, Alan K, and Joe...
