hey guys when originally looking for cams i had decided on the 918 springs, but recently called TSP and was pointed toward the PRC springs, the cam is either going to be a 233/239 .610/.605 or the 231/237 .598/.595 both with 112 lsa. the 918 spring package is cheaper and i would like to know if they would be good enough for a DD that i want to be able to put the cam in and not worry about. wondering if the PRC's are too good i guess you might say for my purpose, and if the 918's would be fine for what i wanted. thanks.

 

TSP gave you good advise!
The PRC is a much better choice

 

get the prcs and not have to worry bout it,they are a great spring,i am running them now,dont go cheap on a key part of ur valvetrain,hope this helps

 

PRC's for the 233/239
918's for the 231/237

918's are fine for both cam choices, but the duals are good insurance.

 

Exactly. I wouldn't think twice about running 918's on either setup.

thanks guys it's kinda hard not to atleast look into being cheap sometimes.

So, choose accordingly

 

thanks guys i guess the PRC's might be worth the insurance i suppose.

 

Bah, you can go a lil' higher with them. If you're risky.

 

Like said earlier, 918's below .600", PRC's above. 918's are a good spring and their deffinatlly not a cheap spring. They just don't cost as much as others because there a single spring, not double.

 

hehe...cool, the heads I bought came with 918's on them and I wanted to run a G5X3, i'd rather not change valve springs if i don't need to...

 

The PRC kit is a REALLY good deal compared to the 918's if you think about what you get in the deal. The PRC kit comes with new valve seals, spring seats, titanium retainers, and the springs. With the 918's you only get a single spring that reuses all your stock stuff.. that should be a no-brainer.

 

what is the PCR kit sorry

 

PRC (Precision Race Components), available at TSP (Texas Speed and Performance).

 

The 918 is actually a better design, lighter mass and better quality spring wire. Oh well....

I AGREE WITH THIS STATEMENT

 

I agree.

The 918's can be shimmed to handle either cam just fine. The valvetrain should fair better up in the rpms with the lighter design. The only reason I'd consider the duals for this app. is for that reason...they're a dual spring. Insurance...

 

yeah, b/c like i said earlier, it's a DD so i don't wanna have to worry about it once the cam is installed. it's only like 89 bucks more for the PRC spring kit. right now i don't have an ls6 intake and i have stock 3.42's think it will be alright for now and maybe a tune not RIGHT away...$$$$ ( ps...would a EFI tune be alright, or just go for the dyno tune )

 

I've got PRC springs and love them. I ran them with the STOCK CAMSHAFT (had the heads off already for lifters) for about about 10k miles BEFORE i put the f14 cam in. Cam is 232/234 .600+ on a 112lsa.

You're probably going to be hating life with that new cam and no tune. Its going to treat you like **** on the street and not have the power to back up the killer idle lol.

Sounds like you just have some more saving to do! It happens to the best of us

 

bingo
