Hey everyone, I'm looking at beefing my car up a bit more, but I need to learn more about what's already been done to her.

I bought this car from a dealership about 1 1/2 years ago, was told it had a cam and headers, but when I got home and opened the glove box I found 3 invoices for engine work done, which including "383 Stroker Kit" and a massive tune up / parts replacement list.

Problem here is not a lot of it is very descriptive and the company that did it does not have a working number that I can find.

It lists the following items I'm trying to decipher: "Head Work $625", "YW Rocker Arms $330", and "YW Valve Spring Kit $240".

Just going off of this, I'm trying to figure out what is actually there. Is there any way I can find out if the Rockers are 1.6s or stock replacement, if the heads have been ported or not(i assume so), and what valve springs have been put on without ripping the heads off and completely apart?

Would be a shame to buy 1.6s, and send the heads off to be ported if it has already been done.

Thanks in advance for the help!

Since I got it I've added a Stage2 Performabuilt Transmission + converter, deleted the cats, OTVC wires(MSD 8.5), and K&N CAI.

I'm still ironing out a ton of bugs and electrical gremlins left for me by the previous owner, and having a frustrating but fun time doing it.

When I bought it, it ran a 14.8 with the mods it had, including the 383, after doing a tune up, and fiddling with tunercat I have it down to 13.3. Not bad considering I'm learning how to do it all myself while I'm at it.

Figure after a new opti, getting the LTs to stop leaking( ), replacing bad 02s, and curing a mild miss in open loop, It should move alot better

 

take the valve cover off, most if not all aftermarket rockers should be labeled the ratio

just take a pic, the most common aftermarket springs for our cars are pretty easier to distinguish

what's a cc304 cam?

 

oh and when you yank off the lt's take a pic of the exhaust ports

 

Comp Cams 07-304-8 Cam

Will be replacing the LT gaskets with some dead soft percys next weekend, will snap a pic with the digicam of the rockers and ports then.

I hate changing those gaskets, PITA!

Thanks
