looking for 13's while staying crossfire

Either a cam or converter will help a lot, w/out hurting anything. A cam is so cheap, I recommend it.
Follow that with "tuning" (whether you do that mechanically or via ECM programing) and attention to detail. That and good driving will put you in the 13's easily w/no power adders and a stock looking, stock driving car.
My car ran low 13's on a junkyard 400 long block, $89 Summit cam, Edelbrock "headers" and heavily ported CFI intake. CFI-EFI's car can run high 13's on a stock long block (w/160k miles), and a ported intake, converter, cat back...and tuning IIRC.
In short, you should be able to hit 13's for under $1000.00 if you're somewhat mechanically inclined.

I ahve some at work. I'll post them tomorrow.
To what? Depending on the goals for your truck, and the rest of your combo (cam, heads and exhaust) I can tell you if I agree w/that advice.

thanks for all the imput guys and the support
i plan on taking the car down milan dragway a couple times in completely stock form to see what im starting with
and for each thing i do to the car i will run it at a test and tune and post the results so others with the crossfire will have a idea of what mods will get there car to the level they want
by the way whats the fastest stock block crossfire injection car run anyway???
guess that might be something to shoot for?

The only thing that I've ever recorded was the hp gain I got putting on the Xram.... which was 36rwhp
So with very little money ( a grand or so like Tom says) you can bring yourself into the 13's... not a bad investment if you ask me

Cool. thanks.
I have a long way to go with the frame-up. My plan is to go with a carb first, then maybe swap in the old X-fire with an updated ECM.
I want economy from the truck, so the cam will be near stock. The X-fire made decent torque and it won't need to rev too high. I already have enlarged TBs and have the manifold stored.
I TPI'd my '84 to a SD system and it is nasteeeeeeeeeeeee.

As for a genuine stock long block'ed CFI car, I don't know that either. I'm pretty certain that if that was you're ultimate goal, you could probably hit low 13's, stock long block, stock (ported) intake.

If you're using a stock cam, the ported intake will be more than sufficient.

Dom ran a 13.3 and ben73 is the record holder @ 12.4 with a XRam'd 383. Mine has a best of 12.95 with a XRam. We are still working on the Renegade manifold but based on the mph increase and lack of traction it should run 12.5 all day long. Just waiting for the weather to warm up a tad. Test n Tune nights on a cold track aren't the best.
