Chevy L99 aka LS3 Cam and Converter selection

62 posts in this topic

So my plans will be these:

AFM/DOD/VCT delete to swap it all over to LS3 cam and valvetrain.

LT's with high flow cats.

I'll probably DD thing thing quite a bit on nice days (no rain, snow, etc.)

Comp has a few cams listed here: http://www.compcams.com/Company/CC/cam-specs/cam-search-results.aspx?sc=55&sm=By%20Engine%20Family

This one looks decent to me. http://www.compcams.com/Company/CC/cam-specs/Details.aspx?csid=1428&sb=0

Question is, do I need a converter for this cam or can this motor be tuned and rev'd that high with supporting valvetrain and actually hold up to DD'ing? Will the trans hold up to that rpm shifting?

I don't want to start breaking parts. I want to enjoy not having an old POS for a while, so I don't mind going with a smaller cam if this one is going to cause problems.

Circle D, Yank, what stall, single disk, etc?

Yes, call BTR, tell them what you want to do and give them a credit card number.  He will put a kit together with all the parts you need, down to gaskets.

I've got the valve spring tool.

I 3rd that. 

I like my little BTR cam. 

 

They give away a cam kit every month (I enter it every month :))  If I win I'll hook you up with a killer price.

I'd be tempted to call Texas Speed and keep the VCT. 

 

BTR is you really want to ditch it all.

The more I think about it, the more I want to keep VCT. :yes:

I want that 0-60 because most of my racing is on the way to work smashing the gas red-light to red-light. :lol:

Guess I need to see which cam makes the best power across the board.

lol   You present quite the quandary to me:  on one hand I want to love ya for being a clutch brother, but that whole "slip on purpose" side of ya makes me wanna pull a H Ross Perot and lock ya in a basement! lol

Add a slick and you dont have to slip.  Otherwise, dumping the clutch will get you nowhere quick!  Why have it if you dont use it!  If you think about it, in every day driving you slip the clutch to get moving from a stop and often times slightly slip it between shifts.  Same thing in racing a stick car on a radial or street tire.  Slip it off the line, give it hell after that.

But is that cam too big for a DD street and strip car?

Any video of that cam at idle?

Should be a idle video on that page linked. That's a mild cam.

doooo iiiiiiiiiiiiiiiiiitttttttttttttttt.

By the time you have those headers in and ready to go in the car you could have the converter in hand and ready to go at the same time.  Sucker would wake waaay up and you could actually use the excuse that you got an auto because its better for racing and be right!  That and some drag radials and that sucker would be nasty!

What's that old saying? you can lead a horse, but you can't lead a blind horse to better times because of mad misconceptions?

 

Literally, the first mod I would do if that car were mine would be a converter. One of the last would be a cam.
