Soo I have contacted 6 suppliers at least for these springs- still waiting for one to get back to me.
As far as I can tell there are 3 springs in washington and some500+ springs on back order.
I have already ordered the performance spring retainers and valve locks.
soooo using either stock spring retainers or the performance ones can anybody suggest a valve spring that can be used instead, without machining.
it will be to fit a comp cams 232 cam

thanks and regards,

Supposedly the gm 3200-3400 Venice springs will work, I haven't tried yet though, my moparts connection got me the springs and locks in two weeks, that was six months ago though

Thanks for the reply.
I looked up gm 3200-3400 Venice could get nothing that made sense on google or wikipidia. - What year would this GM venice be? - might have more luck with rock auto.

Also A search for "my mpoar connection" was a bust.

Agreed Pac has a great selection, gotta do the math though

Take specs subtract 20% from the lightest you think you need and then call PAC. Let PAC do the homework.

These engines don`t run enough RPM to justify HD spring rates nor are the typical cam profiles dictating much spring. All your doing is loading the lifter more.

I would have to look at my notes but I took the recommended Hesco spring for my Hesco cam and knocked the pressures way down. The timing and injector phasing allow for 55-5600 rev limits and the valves do not float.

What springs did you actually use? part number? specs?
Thanks

HESSPRSS6 springs.

Bennie`s recommended 1.7 installed height is too much at 135ish on the seat

Cutting the seat to 1.8 drops the pressures down to 115 on the seat and 245ish @.500.

Perhaps Hesco has speced different pressures over the years because the rates have changed from one generation to the next.

Thanks.
There were no specs on hesco site for these springs.
seem like 260 lb/in which seems about right.

I wonder why only for single groove valves? I wonder why not for '98+ with 3 groove valves and locks. I thought they both were 8mm 8*.
What is there for the 3 groove valves and locks?

Here's another alternative:

In a nutshell: Ford 4.6L 2-valve beehive springs, Hemi 8 deg retainers, stock 8 deg locks.

Engle Cams has a couple of possibilities.

#593 220 pound/inch 1.80"=95psi seat 0.450" lift= 190psi, -or- at 1.65"=125psi seat 0.450"=215psi
#696/697 250 pound/inch 1.65"= 105psi seat 0.450" lift=220psi
#6612 280 pound/inch 1.65"= 110psi seat 0.450" lift=235psi

Need to find out the diameters of these springs.
I wonder who makes their springs?
