I'm planning on purchasing most of this, just need a ballpark idea of what it would run..
Chevy 305 block
Iron Vortech heads
Edelbrock Performer intake
Compucam Camshaft(not sure which one yet though)
new lifters
MSD ignition
SLP Headers
Random Tech 3" high flow cat
Edelbrock 3" catback exhuast
3:73 Gears with posi
and a Custom burned chip..

I'm looking for low 14's to high 13's... I plan on selling my car stereo (getting tired of it) to afford most of this stuff, since I payed over $3000 for the system, I bet I can get at least $1200 for it now (6 months later)...

 

I think you are pretty close with your guesses. Why a 305 block and not a 350? If you are buying a block you might as well spen a litlle extra and get the extra cubes. If you don't yo will be kicking your own butt down the road. I'm serious!

You with the 305 block=

You with the 350 block=

I've already got the 305... In my car right now.. It's slow.. I'm pretty confident I can install all the stuff I listed, but i'm not too sure I can install an entire new engine...

 

If you are changing all that already the only hard part of changing the engine is lifting the 305 out and lifting the 350 in. Are you going to be using your current block or are you buying a rebuilt 305? If you are buying a rebuilt 305 it would only cost a little bit more to go with the 350. If you are using your current block with or without rebuilding the bottom end then it is a judgement call. In the long run you'd be much happier with the 350. Even if you had to wait awhile to do it all. Or you could do the 350 swap and hold off on some of your mods until you have the money. I know several people who have rebuilt their 305s and are now sorry that they didn't wait and get a 350. Bigred305 is one of them.

The current setup I have in my truck will pull a car length on a 2000 Mustwang GT 0-65. The 2000 GTs run 14.6 in the 1/4, and my truck weighs in at ~4500 pounds. I'm just trying to relate to you the experience that others have learned the hard way.

 

He's not lieing. More cubes the better. I am upgrading the 305 cheaply to hold me over until I buy a crate 383 or 396. which equates to getting 25% more bang for your buck in mods.
