I have Hedman Headers, Random Tech 3" exhaust, 160 thermo, fan switch, Poly tran mount, TPI fuel pump and am running the 1/4 mile at 16.04 @ 84.59mph. What should I do next? I'm not real happy with my 1/4 time but I improved .4 over stock.

 

lt1 cam...best bang for the buck..

gears possibly? 3.42's

 

I have a WS6 rear end to put in soon, it has posi, disc brakes and 3.23 gears. and I have the aluminum driveshaft for it too.

 

a 3.42 gear would be your best power gear but 3.23 is a good gear too so i would say your set on that end. I would say lt1 cam is next or invest in some tuning stuff, these cars really wake up after a good tune not to mention you can squeeze some good mileage out of them as well.

 

By a good tune I assume you mean getting a chip burned? Thanks

 

well 3.23s dropped me down a bit i think it was 4 tenths but really it was the adding posi that really help my times go down

are you still useing the stock aircleaner? or running open element
also mod your fpr to be adjustible and bump it up a little

mine ran best with 16 psi fp and timing @ 4 advanced

 

Yeah, I've been wanting to go open element. I'd like to get comfortable with doing the timing but even after reading articles I think I will need someone to hold my hand through it haha

 

timing is so simple just get a timing light and distributor wrench
and you turn it to adjust timing

 

After doing some research I thought a changing a cam was a cheap but time consuming mod, but after adding it up its like 200-300 before shipping and text.

 

there talking about useing a used lt1 cam can be had for 20-100 bucks shipped normaly

 

Eh, what could it hurt to try, gotta be easier than pulling the driver side exhaust manifold haha
----------
What about the spring ($60) timing chain ($50) and gaskets galore ($50-80)

 

intake gaskets water pump gaskets and timing cover gasket really thats all you should need gasket wise but its a good time to also replace the rubber valve cover gaskets

 

I'd say A trans go trans pak fo rthat slush box and then a custum chip

I plan on adding more to it but there you go. Plus all the other stickies at the top of the board.
Plus try pulling some weight out of the car. BELIEVE me it helps. My car weighs 2900 pounds without me and a half a tank of gas. Even now my car pulls quite nicely.

 

I think I may make doing the LT1 cam my winter project, along with replacing both my fenders, fixing my ground effects and repainting my headers and rear bumper.

Ah.. so much work to be done.

On another note I found a guy selling a LO5 engine for under $400 locally, but I was reading posts the other day that taking the LO5 route isn't a good idea now for a daily driver.

 

Whats wrong with the L05 in a daily driver? Its an extremely mild engine just like the L03. For 400$ as long as it runs with no major problems, id jump on it, get that, a nice cam, some good heads. And you can very easily get into the 13sec range.

 

I found that its the truck LO5, so no roller cam
