F-Body Europe

I've deceided what I am going to do. I'm going with the LT-4 street heads from airflow Research. Also with the LT-4 intake from GM. My question is with the cam. Airflow Research recomended a comp cam part# 07-502-8 269 HR-12. It has an intake dur. 218, exhaust dur. 224. Lobe sep. 112. He said it will work with the stock 1.5 rockers or the ones I want at 1.65. Any comments greatly appreciated.

In your case i'd simply go with the GMHP LT4 HotCam.
What better way to compliment the heads and intake.
Also it gives you extra bragging rights

Seriously, with the GMHP Lt4 HC you know that it will work fine, is emmission legal, etc. etc. I think that is worth something too, don't just look at extra HP at certain RPM.

Besides, the Lt4 HC is cheaper that the rest at just $165 for just the cam

Isn't it a high rpm cam though? Someone was talking about Mike's. Thought I heard that. The guy at airflow research said the comp cam was good from 1500 - 5000 rpm.

AFR makes the LT4 heads??? and dont keep the 1.5RR.

Any of the smaller cams, LT4, CC305, or that cam that Willis had are about the same, and they will make good street power.

I will assume that AFR is porting the LT4 heads for you, and if they are you will want to get a extrude honed intake to compliment everything (I believe IRS has one on exchange for around 250.

If you want the LT4 conversion(basically what you said you were thinking about) you owe it to your wallet to contact Pace or SCD Chevrolet, they are offering the kit for around 2-2200k, I dont know of to many better deals.

.......Oh the joy of modding, next you will need a 52mm TB, PCM upgrade, LT headers.........cars are so cheap!!!

Just buy the Lt-4 kit as seperate parts at Sam Taylor Buick and you will be better off than buying at Pace as Sam Taylor SIMPLY is the cheapest.

You guys ever check out my Price comparison page ?????

Yes sirree
There is some killer deals there.

Your talking about "Dal" right Sergio.

He has hooked me up before, you usually end up getting a great deal.

I'm just biased towards pace because one of the techs hangs out around here doing installs on the "real cheap". But you are right, Dal will have the best prices bar none.

Great infos, tnx for the work ...

Not meaning to complain (after all, I'm running on T1 minimum), but did you get any feedback on your page loading too long? Lots of (partly unnecessary) gfx there that might be drag for people w/modem to get ...

Yeah, I found a kit complete with LT-4 ported heads, choice of cam, 1.6 rockers, springs, gaskets, and head bolts for 2200 at internet racers supply. Stage II's none the less. The AFR's are 1750 for the heads alone. Yes they do the porting. The only reason I was leaning toward them was the reputation.

First of all, I think IRS is a first rate business, and I like them alot, but you should know that they dont port the heads themselves, they send them out. The person/company that ports them does do a good job, however you may want to do a search on cz28.com about this, as some people have got really shoddy work. I believe one of them was Jordan Musser. (not sure here).

And second, you did see that the price on the stage 2's also includes a exchange/core charge right? Meaning you have to have LT4 heads, to get LT4 heads. I cant remember what the core charge is, but I think it was around 1k.

I'm definatelly not knocking IRS, cuz I use them alot, but since this is alot of money, you should check out Velocity(GTP heads), MTI (package) Agostino (package) just to see how they stack up. Do not go budget here, thats kinda like buying the cheapest brakes (they will be the cheapest) with in reason get the best you can afford.

and BTW, since you have to remove the timing cover for a cam anyway, I would research a better oil pan/pickup, preferably one with a windage tray, an you really should think about the meizere waterpump, it really is the smart way to go.

Robert, NO i'm NOT talking about Dal Lambert Buick but Sam Taylor. He's A LOT cheaper than even Dal Lamberts from who i got my 1LE swaybars 2 years back.

Garry, Some people did mention it and it's logical as it's a heavy graphical based website, but since most people nowadays run ISDN, Cable or even DSL the loading is minimal.
I have a crappy cable speed and the page loads pretty decent (cache turned off !).
I believe in good looking websites so i choose this route and remember that good things come to those who wait
I understand with a 33k6 modem the page is kinda slow but i choose opt for faster connection speeds just like choosing for a 1024x768 resolution as 17" screen are pretty common nowadays, you have to draw a line somewhere.

That's the reason I was leaning toward airflow research. They do the porting themselves, and to your specs. I'll look around some more.

AFR is good and their heads have more meat then LT4 castings. However I believe they have a different angle in design of the head (degree) to the block. IRS is ok (sorry Rob) but they don't send your stuff the when they're supposed too. Too many problems in the past and I stay away from them like the plague.

ARE is well known and so is GTP. It all depends on what you wanna do w/ the car of course. MT1, LT1motorsports, and I believe Beckracin do heads too.

Personally I'd go GTP, ARE, LT1motorsports, in that order.
1.65rr you'll need new valve cover too......just something to keep in mind.

Comp cams makes a 305 grind cam kit(rockers,springs etc) it sells for $289.00 that's what I would recomend if your going to do it do it right the first time.

Let me correct that, $229.95 at Nu-Tek motorsports with ANY grind and even a custom grind if you like, for instance the 305 with a Lobe seperation angle of 112 degrees instead of 114 degrees.

It's obvious that you don't seem to check Z20-Paid for the lowest prices, shame ...

Is Nu Tek a distibutor or a manufact. And if there a Manufact how good are there cams verse comp cams. I've never heard of them before so I really don't know. I know when I rebuild my engine I'm rolling a COMP CAM. Everyone has there own preference.

You basically have a couple choices, and then you give your money to who treats you the best. Really the only variable is do you want a custom grind cam or not. Because the differances in ported heads or intakes (if you stay streetable) isnt going to be huge IMO.

If you are going to do it, like was mentioned a couple of times, do all you can the first time. This can be one kick ass power maker of a mod if done in a matched combo.

But remember there are alot of nickel and dimes to spend on the supporting cast, or you just bought a 2k lopey idle.

Happy Head hunting
