Default 418 LQ9 What cam to run?

Hey guys looking for some suggestions. I have a newly built LQ9 stroker 418CI and was wondering about a cam choice for this. I have the TPIS 90mm intake and throttle body, PRC stage 2.5 5.3 heads with 2.10/1.60 valves, long tube headers and SLP exhaust, underdrive crank pulley. Any suggestions appreciated I have a Torquer V3 with 200 miles on it out of my 346 but dont know if this would be a good cam for this motor? If not would be willing to sell it.

Ditch the TSP heads, those are seriously mismatched to those cubes.

Your current cam will be all done by 5800 w/418"...perhaps a custom in the
range of 238-246 @ .050 will get you to 6400-6500 range

This may be a little off topic but.......I never understood the "help with cam selection" posts. Agreed there maybe a COUPLE cam guru's on this board but it is truely hit or mis. IMHO...just call the pros..the ones that will make a spread sheet on your combo and give you options with moving the valve events around to compliment your specific combo.

Examples..
Erik @ HKE
Steve @ LSM
Geoff @ EPS
Mark @ Bullet
you get the idea and the list goes on....pro, as in they make a living dealing with these variables.

Here is a thread on the bullet that will be a good read for your situation...

Thanks...and good luck with your build.
