I am running the Comp918 springs on my car right now with the titanium retainers. I did not make any changes to the heads and am still using the stock seats as well. My buddy (and roommate) who works at Comp recommended them to me and I have been pretty pleased so far.

 

The 918's run a 130# seat pressure. I read on another site where it said they'd be good to ~.660" lift, so you could most likely run .625" lift with no problem.

 

Dumb questions.... why did you use those locks with +.050? cause the price? and second dumb question, where did you get the 26915 springs from? I could not find them at compcams.com, thunderracing.com and Jegs.

next dumb question... the retainers...its listed as "steel retainers for bbc beehive springs" Whats "BBC"


Ok thats enough for now.

Ok I am gone for now..

Thanks in advance.

MentalCaseOne,

I used the +.050 locks to achieve the most installed height with
off-the-shelf parts. Because the spring shim/locator is .062" thick
it takes up quite a bit of height compared to the stock shim which
is in the .040" range. I mocked up the beehive springs with the
standard 7* hardware and the .062" shims and the installed height
was 1.72" which was too short (too much seat pressure) for me.

The 10* super lock retainers are the big block retainers (hence BBC).
I used a stock length pushrod. I purchased my springs from:
www.speedrace.com

 

Looks like speedrace.com has deactivated their parts catalog... I ended up in E-bay and then it said the store just opened up and to check with them later...
