Hey, it's 3am right now and I'm really tired, waiting for sheets to dry

So here is a before and After Pic of my engine bay. Just thought I would share.

Nice . I like how clean it looks, without air conditioner and such! Mines a daily driver though so doing that would just be pointless, as least for me I like having all the little extras.

Re: Engine: Before & After

Is it a 350 swap? What did you do about the chip?

Re: Engine: Before & After

If your asking me, mine is not a swap. We kept the 305 and just dumped a butt load of money in it. It's not the fastest car in the world, but it rides and sounds nice. I also haven't been able to switch the gears from 2.73 to 3.23 yet either...so we will see how that changes the ride.

I currently have the stock chip in it, but I have a chip from TBI chips (on ebay) that should make a nice difference too when I get around to putting it in.

Re: Engine: Before & After

my a/c was bad. mine is not a daily driver either. mine is the stock 305 tbi with a bunch of extra work. made my own harness and have detailed just about everything including mounting things hidden. 4th gen overflow and washer bottles with a stage 2 tbi chip. 350 swap will be next year.

Re: Engine: Before & After

There's a guy on Craigs List that burns a costom chip for you. I haven't used him but I think that would be better then a mail order chip. He hooks up to your car and goes from there. I am sure I have his number if you want it. He is even in Vancouver and he comes to you. I personally went with the EBL and am doing a 350 swap. You engine compt. looks great. Did you use a costom A/C delete box on the firewall?

I see you got rid of the piece of wood as a hood prop....that probablly made at least an extra 10hp's under the hood.....

Re: Engine: Before & After

lol, yeah my hood still doesn't stay up on its own, we had a pair of vice grips holding it up in the "after" pic...I need new shocks.

PS: I know there are other threads for this, but if anyone else wants to post there pics too I'd love to see them! As if I don't have enough to keep me distracted from my work! lol
