Hey all,

Contacted LE and told him my mods and on stock heads and stock intake he suggested the following.

"Dear Lloyd Elliott and Co,

Hope you all are having a great Labor Day weekend. Had a quick inquiry for you guys about a custom cam for my LT1. Below I will list what the car has and just some specifics about it.

Car - 1997 Camaro Z28 A4

Mileage - 75,260

Uses - Street driving "Racing" with eventual mild strip use, weekend car, non daily driven

Mods done - Pacesetter Long tubes, Pacesetter Offroad y-pipe, Underdrive Pulley,lingenfelter full cold air intake, Throttle bottle bypass, Strut tower brace, subframe connectors, motive high performance 3:73 gears, TA performance girdle cover, TA performance stud main bearing cap kit, solid pinion spacer, full richmond rearend rebuild kit.

Dyno numbers before full cold air intake and not the best dyno tune - 270/300

Future plans - Yank SS 3600 stall (spring 2014 / summer 2014)

I don't plan on doing head work or intake work anytime in the near future. I would replace my roller rockers with 1.6's or 1.7's and I really like what I see from the dual springs (could handle a larger lift if I wanted to go with a bigger cam later down the road). Would you suggest new pushrods while I'm in there getting this work done?

Some cams I've been looking at - CC503 specifically. I don't mind a choppy idle or a bit of surge. I personally like the sound of a cc306 but I know heads and intake work is needed to make that cam do it's best work. We can go as radical as you guys think we could go with using stock intake and stock heads.

Thanks for your time"

His response:

"I would use a 231/239 .571/.587 110 LSA cam.

This will work great with 3.73 gears and 3600 stall. You will need to do the stall at the same time as the cam.

$300 for a custom cam.

$250 for Lunati 73925 K2 dbl spring kit with springs, retainers, locks, locators and seals.

You will need 1.6 roller rockers, good pushrods and tuning"


Some questions - Thoughts on the Lunati 73925 dbl spring kit? Any suggestions on roller rockers and whats all needed (thinking comp cam pro mags 1.6), any pushrod suggestions?

Thanks,

Devin

 

Hope something could chime in, I figured getting the gears in first will be my best bet since I have to break them in. And I'm assuming with tuning on the street and on the dyno there would be some full throttle runs and I don't think that would be the best approach with brand new gears. Just trying to get everything in order so I can order all these pieces, get my gears in and then start saving for my Yank SS 3600.

 

A cam with 231 degrees of intake duration is a whole lot of cam for a stock compression/stock heads/stock block LT1.

If it were my car, I'd be looking at something along the lines of a CC-502.

But then......that's just me.

Thanks for the opinion and input. I know LE makes amazing custom grinds so I'm a little curious as to why he or his co would suggest an intake duration of 231 degrees if it's too much for a stock headed LT1? I've heard CC305 is a great cam for a stock head and intake lt1.

 

I have that set up and it pulls great. Just get everything through him you will NOT be disappointed!! It is not to much for the heads!!

 

Damn I have the Same set up to but, I have LE2 heads also no vid of it...must be good if he setting people up with it...as for pushrods he told me trickflow 7.200 but would be better to use a pushrods checker and go off that

 

I would say that the LE2 heads with a compression ratio of about 11.2:1 to 11.5:1 would ba a MUCH better 'fit' for that 231/239 degree cam.

Personally, If I had a stock headed F-body, I'd do a bit of a custom cam with the CC-503 lobes (maybe even the CC-304 lobes), 110* LSA and 5* advance ground.

But like I said......that's just me.

Weekend only car, non-DD, Aggressive Street/"Racing" use, some strip time...

Seems like he specced it right on as long as you were being honest with the intended usage and mods.

On a DD with poorly ported stockers and a 3200 stall I loved my 227int cam. It was recommended by the now out of business Nevarez Racing/CMotorsports as their largest recommended stock shortblock/stock head/auto grind. They also had a cam similar to what LE spec'd you touted as the largest recommended stock shortblock/stock head/manual grind.

LE won't steer you wrong - as long as you give him the right info he will give you what you want.

 

Well he said he mill the heads .020 and with the 5898 gasket .026 I should be at 11.1... But I do agree custom cam with the cc503 lobes sound nice.

 

Get a custom hydraulic roller from someone that knows what they're doing with profiling. You can have two different cams that have the same @ .050 numbers (along with the other numbers you see on the cam card) but have radically different lobe profiles... because that's only looking at one aspect/measurement of the cam itself.
