hello,

I have some plans for the summer... heads, cam, forge internals... you guys know the deal


Now, I know that the instake on '93s looks a little different from '94-up, and I was woundering if a set of 94-up lt1 heads will fit my car with no problems.


Also, can you guys give me some info about what are normal flow #s on the stock heads and what #s should I be looking for if I buy a set of used heads or if I get a port job ( with $1,000 limit)

Thanks a lot

The '94+ heads will work fine. As far as stock flow numbers go a few people on the board have posted them and there are two different sets because in either 95-96 they changed the casting on the LT1 heads. They are basically the same but they flow just a little bit different.

The heads will work but if your going to port them then 93's are a good casting something like more material, I have the 92 vette heads (same thing) my 93s sold VERY quick. It also depends on goals I would spend my money on heads before forged internals unless I was doing alot of boost or BIG shot of N2O. You have to figure out what you want for the end result if you don't you could waste a bunch of money like me

Just checked out your website NICE ride!!

Let us know your goals and we can answer your questions better

Thanks for the info...

Well, my goals were to run 12s N/A and 11s on the bottle (100 shot/ stock internals) In a daily drive car....

but for some reason now that I ran high 12s I feel that I should get a bigger cam, heads, bored it to a 355 and see if it takes me to high 11s and then (with forge internals) be more confident to run a bigger shot on race gas at the track (did I mention fuel upgrade too? )

It's the never ending story of spending money on ,my car.

I migth have $700 soon and I was woundering if I should start by buying some already ported heads

P.s. thanks for the complements on my site

93 Purple grey TA, WS6 chrome rims, Firehawk hood, hyperco spring, kyb AGX's. Hotcam fully ported heads, mac headers etc..., T56 conversion, Mcloed clutch. 12.69 @105.88, 1.74 60ft with Nitto's with old A4


With a hotcam and fully ported heads... running 105.88? what it's your elevation?
I was think to get a scan tool to see if I'm having some kind of knok or wait until the track re-open to see if I could get better times, beacuse I see people in here all the time running our times with just bolts-ons?

My 3rd gear clutches were burnt up I ran 108.9 with a rebuilt 700r4 and 3.23's. Haven't been to the track with the T56 and soon to come 3:73 gears.

12.8 is good for a cam only car. Do you realize how fast that is? Most bolt on cars running those are setup to run the 1/4. My car is lowered to the ground with 17 inch rims, the suspension is not good for traction and that is what the 1/4 is all about. I usually have to feather it out and then I still spin as it hits 2nd. I got relocation brackets for the LCA didn't help at all I would like to see the time I would run with Hal setup and ET streets. Most guys with similiar setups are running 12.4-5 with that. Don't let those bad boy bolt on get to you.

Really your car is running pretty good. Its one thing to go from 14.01 to 13.5 its a WHOLE OTHER thing to go from 13.5 to 12.8!! and it gets worse. I've got way too much money into this thing. I'd love to get a new car but I would loose everything....

Your ride is sweet damn with some good heads and a 100 shot you'd probaby hit 11's! I just looked at your web site if your car is running fine now a set of heads and 100 would probably get you REALLY close or in the 11's if you can hook. If those are your goals forget the whole forged setup. If you keep the 355 get a good set of rods and forged pistons, or go 383 with a scat crank that would meet your needs well with traction and a 150 shot you would be VERY deep into the 11's.

Course that is just from my experience and friends around here I've never actually ran an 11 I'll tell you about that in the Summer

thanks Bobby,

I only did 3 passes with my new set-up, (before they closed the track ) and let me tell you those ET street can hook! The first pass my hand came off the shifter and I found my head been hold by the seat. The sencond and third pass I was a little more ready. I loved the feeling of hooking up

can I get a decent set of used heads for $700-1,000? or a port job for that matter....

You might wanna consider getting 24# or 30# SVO injectors while you're at it to replace the stock 22# units.

donot_4get

hmm... I was thinking to get first a fuel press regulator and a fuel pump. but yeah, I need injectors too

I have a good friend who ported mine and his own that may be willing to do a set for around that with the machine work. Only problem is time it takes awhile if you could get a another set to him he might be up for it he is working on a 383 Turbo setup for his car right now. If not I think I would save another 500 and get them done by the guy that does them on the board here can't remember his name Skaradom or something but he has some cars with his heads that are getting good HP numbers......
