heres what ive found,

caliper at 0 (ignore the dial its off alittle i went by the stamped area)



spring compressed to 2in



spring compressed .520 thou past 2 in



spring gap inbetween coild compressed .520 thou under 2in (pic 1 coil 1)



spring gap inbetween coild compressed .520 thou under 2in (pic 2 coil 2)



so it looks like i have from 60-90 thou of room between coils does this mean i can use the springs and not worry?

 

these springs are off of sportsman 2s for the older small blocks, ive talked to a few speedshops and they said as long as the valve is the same diamiter they will work just fine, because the lt1 can handle upto a 1550 wihtout needing machined

 

I don't know what you're trying to measure compressing the spring to 2.0", the max set up height is 1.750" with a weak 90 # seat pressure. As stated you will be limited to a 1.5 rocker and third, probably have rocker/retainer clearance issues. There are better choices.

 

OP


since your motor is on a stand and easy to work on....

if you now have a spring locator that fits the head properly (no slop around valve stem guide base) and clears the inner spring just install two on any cyl (#1) then rotate engine and when spring is fully compresed look to see if there is any clearance between coils which should be a min of .035. also confirm you have no rocker to retainer conflict

good idea to see wtf installed height would be but you need a spring height tool to confirm they are 1.700-1.750. The specs you publish show what seat pressure is at those installed heights.

 

my motor isnt on a stand, its in the car, i just have a set of lt1 heads laying around that im using for sizing everything up.

im going to check all of this tomorrow and if everything checks out im using them,

 

just checked rocker to retainer clearences, not a single problem. no rubbing or touching at all, pics below, im using stock rockers for now as to not over do it with the springs, so i now prob have an almost stock lift cam in it, so ill end up swapping springs next time i get the extra cash and time ill install my 1.6s on there and new springs, just dont have the cash at the moment.

 

ended up just saying screw it and buying behives so these springs will now be up forsale, took these springs to a local speedshop and they confirmed what springs they are link will be posted in forsale thread

 

A lot more to selecting springs than addition and subtraction. What are the full cam specs?

Without more details I'm not sure what's worse, the ebay springs measured in millimeters or the mystery beehives.

I'll give you some advice, cutting corners on valve train is going to leave you with some interesting garage wall art.

 

the beehives arent a unknown spring that im getting used, im buying those new form a local speed shop that i brought my cam card to and they matched them to the heads, cam and lift i needed and then some, because i plan on running a bigger cam like the 292xfi here soon

 

Why not buy springs from whoever ground the camshaft? Search "broken beehive" and see what you find.

 

SS

the "bee hive" spring most commonly used in the LT1/4 is the Comp 26918 aka "918's". Other brand bee hives also use the same part #

Been running them for years and they are the spring spec for the Comp "XFI" grind cams.

Years ago there were reports of failed bee hives associated with a specific "batch" #.

 

Ill check out the broken beehive thing. So far so good though.

 

the broken bee hive thing was years ago and associated with one particular "batch # of Comp 918's. I have had mine in 2 diffrent motors with zereo issues

 

Any clue on the batch number? I still couldve gotten a set from back then. Cause i know these things sit sometimes

 

They had a blue stripe on them, the new redesigned spring is all silver.
