Well, I've decided that a cam swap is really too much for me to take on right now. I just can't see spending all that $$$ for a 25-50hp gain.

I was wondering what suggestions anyone might have as to what direction I should take with the mods (check sig for current mods.) Should I continue with motor bolt-ons? Should I consider drivetrain mods (gear/converter/shift kit)?

And, by the way, I just ordered some electric fans! <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

I've never heard of a cam alone picking up something 25-50hp. Wow thats cheap hp you better do it next if you are going to get that from a cam alone. I would look more towards 10-20 tops out of the cam. But for the money spent it is still one of the best additions. That is a real power maker, not like ELECTRIC FANS...lol

Our 9.5:1 CR makes it much harder to get the 25+ RWHP gains seen in the F and Y bodies with cam only changes. Dynamic compression changes with higher duration cams and combined with the effects of low CR tend to give you diminishing results.

if i put in a cam and got 10-20 i would be pissed.

bigtex(richard) put in the ls6 cam and gained ~30rwhp. a few others have had similar gains with this cam.

another guy put in the 212/218 cam with a gain of something like 42rwhp.

now with raised compression you would gain alot more, but we can still have respectable gains with our low compression ratios

Yes those gain ARE attainable but from what I recall SCREAM's truck is for the most part stock and a 4.8.

Yessir, I stuck myself with the lowly 4.8! I've added my sig to the post so you can see what I've done so far.

I work at a speed shop on the weekends, and was looking at the Comp Cams 412-11 (212/218, .522 lift and 114 LSA) but my cost on the cam is a little over $300, and the springs are around $125. Add in installation, and it gets to be a little expensive!

I know that there is no such thing as "free" horsepower, but I am on a budget and want to maximize my "mod money." I just wanted to see from people with experience what works and what doesn't, and maybe which direction I should move in. Thanks for all of the help guys!

ahh yes, forgot he had a 4.8L if you were going for a cam i would say a 206/212 112lsa comp grind. better for low end performance which our 4.8Ls need and you can use ls6 valve springs to save money (525 or lower lift).

but i definatly would go for all the bolt ons first. headers and what not, change to 3.73s and a posi or locker. all that stuff

 

seriously all the boltons on a 4.8 dont equal up to that much. just get a NX wet kit and start off with a 75 shot. you will be much more pleased with that.
