why didn't you use your lt4 springs? theye are more than enough for that cam...

henryz28

I was told that they arn't that good; I was told that they are barly good enough for that cam and the 1.6 rrs.I want somthing that will be more than good enough.

I think the max lift on the lt4 springs is .525 and the hotcam lift is .525 without the 1.6rrs.

lt4 spring example: if your install hieght is 1.78" and coil bind is 1.085"... that leaves you with 0.695" of lift... then you have to deduct 0.060" of lift for your green zone(which is the recommended distance from coil bind) which leaves you with .635" of lift with 1.5 rocker arms... now if you have 1.6 rockers then you must subtract an additional 0.034" from your lift... which would then leave you with 0.601" of lift...

and your cam has 0.525" of lift which would give you 0.076" of safety...

more than enough...


check my work guys, i think i got everything...

a stock lt4 cam is 0.467" lift on the intake
and 0.480" lift on the exhaust...

depending on what kind of money you want to spend and if you are going to install a bigger cam in the future has alot to do with the decision you will make...

if its money then i would get the lt4 springs...

if you are going to go bigger some day i would go with those 26918 beehive springs from comp...

henryz28

I think I am going to go with the comp beehive springs;never know if I want to go with a bigger cam latter on and they are a lot stronger spring.

Although I have the 26918s installed, I did seriously consider the
Isky 235-D springs first. If you want to save $$ the Iskys will do
the job with all the stock hardware. You can do a search for more
info.

Then get the beehives, more than enough spring. Plus you can use them down the road if you change cams. If they won't work with your next cam, then all I can say is, "damn that's a big cam".

henryz28

Are you saying that if I get the Iskys I will not need anything else but the springs.I can just reuse my stock hardware.

ZL1modified

how high do you plan to rev?

i don't think the stock hardware is meant for a high rev definently not with springs with high seat pressure... i.e. 6000 and up

henryz28

I really don't plan on reving it pass 6000.

You can get the 26918 springs as said before and I'd recommend those if you can afford them. Make sure they'll work with the self-aligning rockers that come with that kit and get the +.050" hardware for the LT1 heads.

There is a nice kit from Crane that should work with that cam and plenty of others as well and it's cheaper. The main benefit to the 918's are that they're a much lighter spring.

if you go big in the future you will almost have to rev high to get all the benifits of the cam... ditch the stock hardware...

henryz28

Ya I am just going to cough up the extra cash for the beehives.Thanks
