What cam and do you have any video of it RS/SS 4.8? Also did it make good power increases for you? Would I need to buy springs and push rods?

 

Its a TSP 220 kit that I got from texas speed a couple of years ago, it came with springs & pushrods. Yes you can feel the difference especially after 3800 rpm. BTW there are probably better cams out there for the 4.8 now than there was 2yrs ago so I would probably get one custom specd if you want a cam. All I have is an idle vid from like 2011 lol

I did a 2500 stall and a fully built trans with a killer shift kit along with 4.10 gears.
Spring wrap was a total pain! Caltracs to the rescue.

 

I've been trying to convince him to do a Cam Motion/Crane/BTR "drop in" cam. And 4.10 or 3.90 gears. But, it is always easier to spend someone else's money.

 

3200 circle d converter and 4:10 gears are the first thing I did to my truck huge improvement

 

The best bang for the buck on just about any vehicle is gears. With a heavy-*** truck and a relatively small motor those 3.23s are killing you. If I was you I'd do 4.10s first and see how you like the truck for a few months. Then find somebody with a high-stall converter and drive his truck before you invest in one for yourself. I've had loose converters and didn't like them at all for the street - although many guys love 'em. With a 4.8 the converter will be a necessity for the strip.

A cam will just make the truck feel worse unless the truck is geared properly, and depending on how radical you go with the cam you might have to have a converter too - even just for the street.

Good luck, and have FUN with it!

 

Or you could do a manual swap and light up the tires whenever you wish...just dump the clutch and watch 'er smoke....if that's your main goal.

Gears are the king though.

a stick and a 4.56 swap will make that 4.8 feel awesome

 

I was just a little disappointed the truck wouldn't even spin tires with the horse power that it has. I'm not so set on having to spin tires but I would like for it to feel strong from a dig. Especially with over 300 hp and over 300 tq.

 

Well, yeah it's a pretty powerful little motor. I've driven a few and they're fun but they don't come alive until they wind up a little bit. Your 302 rated hp is at 5,600 rpm and your torque peak is 4,600 rpm. Your stock converter is holding probably at 1,500 or 1,600 rpm off the line where your hp is what: something like 120 or 150? With no help from a nice deep gear ratio to multiply the torque you don't have much from a standing start.

 

Remember this is not a 1985 Chevy with 215/75/15 tires on it and an open diff. 100hp will light that up and go till the tires burst.

With posi and 20-22 inches (width) of rubber contacting the pavement lighting up the wheels is exactly what is not supposed to happen.

You are also putting that 300hp to the pavement (minus drive train losses) and using it all, instead of spinning and going nowhere.

I agree 100% with everyone else...TC and gears are definitely holding you back...3.23 gears are shyte.
