I want to add HP and Tq with out running the LS7 to 7000 RPM"s any one thinking of doing this?

razorz28 · 06-17-2014, 10:33 PM

If I ever get my car I am going with the Davenport package that was shown here a couple weeks ago. Maybe minus the headers to start.

Already have two sticks waiting on #149 brother......last minute decision as to which one will go in. Can't decide man....

Either will sound like the 7 swallowed the devil himself.

Big question is will this : GMPP 88958766
fit with the stock pistons and hyd lifters.

It's only .570" lift, but with a 106.5° LSA and 239/251° int/ex duration at .050".

I always liked GM parts.

Big plus is if someone asks you if it has a big cam in it, you can honestly say it's Showroom Stock.

That one you will need to machine the pistons, and its a thumper with that lobe separation.

I have a cam in mind, 226/236 int/ex with 630/620 lift and a 116 LSA its a good cam for track use.

I have a tool for cutting valve reliefs on LSx engines without removing the pistons.

IIRC, Iskederian? sold it to me? I used it on our Z06.

2SSRS@Gen5diy · 06-18-2014, 11:15 AM

where can i get one.

McRat · 06-18-2014, 11:40 AM

This is the one I used, IIRC. Might still be in my tool box.

HOWEVER, the diameter of the LS7 valves is bigger, so mine won't work, you'd have to order based on valve size:

2SSRS@Gen5diy · 06-18-2014, 11:55 AM

Thanks for that.

b4z · 06-18-2014, 11:59 AM

I'd move the LSA from 120.5 to 114-116.
Man that 211/230 split is ridiculous.
I would probably go 224/232 I know, hardly any change but I like milder cams.
Then a .580-.600 lift.
Will pick up a few hp and sill have good drive ability.

You guys don't need to reinvent the wheel...

Visit the Vette forum and see what people are running over there. Lots of proven combos.

Unreal · 06-20-2014, 04:57 PM

Yah the cam specs talked about are way out for what most people run.

I ran a 240/250 .660/660 110+3 and it was fun. Drove good and sounded mean. If I could go back I would do something like a 236/246 630/630 114+3.

Remember the 1.8 rockers mean the lift is going to be bigger, and the 427 can take a lot more duration/overlap and still drive good. I know plenty of people running 246/258 range cams in street cars making 600+rwhp n/a.

106.5 LSA......FTW
