Getting everything together for my cam install and I'm trying to do something with my heads as well. Decided to run Howard's ASA cam because I like the low lift since the truck is my daily. It's an 05 silverado with a 5.3 l59 and 706 heads. Was going to pick up a set of 799s/243s to go with the cam, but how would the 706 heads do with the ASA cam? maybe port and polish them instead of buying new heads?

*One more question... I have a 3200 stall right now, should I get my converter restalled to a higher stall speed for the ASA since its a pretty big cam and low end will be dick?

I would use 799's and keep the stall if it was mine for a dd

thanks bro. I'm just really confused and re-evaluating everything now. Every time I think I know what cam I want and I make a decision I change my mind lol. Now I am having second thoughts on the asa because of some of the things I'm reading and what people on here and other boards are saying.

I've never had a ASA cam behind a auto can't comment on that. But, have had it in past 6 speed fbodies and it's in my LS2 going into my TA soon as its back from paint. Are there bigger better blah blah blah cams yes. But I love my ASA cam cause it sounds mean, the valvetrain is stone reliable and requires no special springs or maintenance that you will have to do with many aftermarket cams. It's a install it and forget it cam. This is the cam and standard LS boltons I have used for my recipe to spice up my LS cars for years and years. Never had to change a valve spring never left me walking.

For a Auto you need 3K+ stall, longtubes ORY preferable, and some decent gears 3;73's or 4:10's in order for it to be tolerable for a DD. It's a rev happy cam harder you wind it harder it pulls. I suspect with a auto it'd be touch flat without a big stall until you get it wound up. My TA with a stick and 4:10's you never feel that zone because it winds through it so fast.

GM puts it in their GMPP 525hp crate LS3 engines with a warranty for a reason.

To answer your question though some idea of what it's going into would help theres a myriad of 5.3's produced from 99-2015. A set of stock 799's or 806's would be fine unless it's a newer model that has flattops then go with 243's. 243's on your run of the mill 07 back dished piston 5.3 kills your compression. The newer 5.3's with 243 heads have flattop pistons
