Default Daily Driver friendly cam

If you had to pic a cam for a daily driver, 4.8 powered truck that gets thrashed from light to light in town alot, and still driven alot of miles a year which one would you pick..

Still want good torque..

Want a noticable idle change difference..

Want to be able to swap it into the 383 Stroker LS1 im building to put in the truck eventually.

Currently doing 3.73 rear gears, corvette servo and the 4th holding servo.. Probably this weekend.. Waiting for pinion bearings to get here..

Thanks

Let the arguments begin!!

Safe answer is a generic 220/220 cam, there's a vid on youtube of a white single cab with TR220 in a 4.8 with headers and it sounds really good.

But what works in a 4.8 won't work in a 383. There's almost 100 cubic inches difference, and if you're doing any head work, you'll want a cam with closer to .600 lift and 230+duration numbers.

There's obviously more to it than what I just laid out, but I think you're gonna need a diff cam for both applications

Anyone have any advice on the 219/233 thumper cam?

sounds sick, but does is have vacuum issues??

I really think the GM ASA cam and the LS1 hotcam sound good..

What does everyone else think, i agree that i am probably going to end up with a different cam in the 383.. however this engine will probably find a home in my El Camino if that goes in the truck so i will cam this one until that time comes..

come on, part numbers, specs, where to buy... Keeping it on a budget..

Thanks

I called up Lunati (always had good luck with their products) talked with their cam guys.. They recomended the Lunati Voodoo 60511.. Claim it will have a noticable idle, and will have good street manners with a tight convertor and still give the 4.8 a really good power pickup.. Going to use that in corolation with the Comp Cams 54050 valvetrain upgrade.. .600 springs, locks, Pushrods.. The whole works..

Anyone know what gaskets i will need? Or do these things use o-ring style gaskets now.. never pulled a new one apart.. Used to working on 2010-2013 15 Litre Diesels..
LOL

Almost all the gaskets are a rubber o-ring design now, and can be re-used provided they still give adequate sealing. I think you can visually eyeball if the oring is sticking out enough out of the front timing cover for example. There's a kit from gm with all the o-rings, can't remember the part number off the top of my head, but if you do a search for LS1 valvetrain gaskets I'm sure you'll find it...

Head gaskets need to be replaced, and you can't re-use the crank pulley bolt or any of the head bolts.
