I seen in the sticky that patiot duals could be used but was wondering what everyone else uses. It will be stock bottom, stock cam, 317's and a D1sc with fmic set on 8# pulleys(I know, disaster waiting to happen). What are you guys with similar setups using?

 

Im going to be running ls6 yellows @ 6psi with my turbo setup. Should hold me over until I have a forged motor :p

 

Yeah, a forged 347 is next on the list after the D1

 

I have ferrea dual springs and stainless valves in my 317 heads.

 

dont know how much truth there is to this statement, but i have been told by some locals that a set of stock springs on 241 heads will start to let loose after 7-8 lbs.....? like i said, dont know how much truth there is to this.

 

patriot golds dual for the last 3 years and have not floated them yet 15-18 psi

 

Very true probibly start floating earlier like 5-6 lbs.

 

A fresh set of LS6 springs on a stock cammed centrifugal setup will make it too 8psi, I would run at least 1218 PAC springs though.

 

Must be nice!!! 2nd set of Patriot Gold Extreme's and I floated the first set and a set of the best springs that come with AFR225's.

 

^^^Whats your set-up though?

 

1999 Chevy Corvette Fixed Roof Coupe
SW/BM 408ci w/AFR 225's 72cc
Patrick G 224/230 .609/.604 114LSA +2
TTi X kit with twin T3/T4's A/R .82

 

^^ how much psi ?

 

I'm going to go with at least patriot dual gold's to be safe. I also heard that prochargers 8 psi pullies actually make about 10-11 psi. Any thoughts?

 

I would like to know the RPM and also the lifters you are using? Also are they shimmed?

 

How much boost & how high are you spinning it?

That lift isnt too bad on that cam. You must be beatin the **** outta that thing to be blowin thru springs like that.

 

not to go offtopic, but does someone know the specifications for stock L92 valve springs?

 

a buddy of mine has this set up with stock springs, 241 heads, around 8 pounds i think, he hasn't had any problems been with the set up for over a year now

 

Thanks for the opinions guys. I'll probably go with the patriot dual golds

 

good choice you don't want to skimp on the valve springs..... Might even think of gettin the extremes just a little more doe. Might as well in case you decide to up the boost?

 

haha yeah... I'm going to try and keep it at 8 until I can forge the bottom end... I can get a replacement for cheap but don't care to pull an engine if I don't have too....
