IMO
i would go with a set of dart AI heads
If you dont want to wait for them
AI TFS heads
both are an excellent head for the LT1
or...just skip heads...buy a turbo...and run 10s anyways haha

 

I would call AI. I know they do good work and their combinations have proven results. As to the LE3 option, I have no opinion.

 

Trickflows are better than darts. They aren't all that person hyped them up to be.

 

I'm not putting a turbo on my car, I'm not a fan. I'm more old school muscle. Although, I could have a long time ago, I have 13-14 turbo's of various size and make laying in my garage as we speak. HX52/HX35/HX55/HX60/HT3B/Garrett's/CAT's, etc. I already have a turbo car, it has 6 cylinders and rattles.

Darts and TFS heads are nice, they are definately being considered. TFS's obivously are a proven head.

Built: Sounds like you do have an opinion. Let's keep this on track.

If you REALLY want to go fast you can do what I did.

My car is so heavy with my fat butt in it, it really does not shine. 3800lbs and a tight converter tends to do that.

At 3500lbs 10.60's would be what it would run in good air. All motor on pump fuel and drag radials.

I am gonna try and get it to run high 10.80's like it is now. More times coming soon.

But I have RHS heads converted, solid roller and a Supervic on a 383. It made 463 to the tires with 2 hurt pistons, probably 470+ plus now through a 4L60E and a 9 inch Ford rear. Stock opti and electronics, full exhaust out the back with no cutout.

You have alot of options for sure, Gen 1 heads are falling out of trees used, conversion is $400 a Super Vic bolts right to them with no changes.

As a matter of fact not long ago there was a set of heads and intake in the for sale section JUST LIKE MINE for DIRT cheap. Have them converted wammo big power.

I'm well aware of those options too. Although one of the things I want to do is keep this like a LTX as much as possible. I dont want a rear mount distributor, Super Vic, Carb, converted heads, etc. I want a LTX intake, heads, throttle body, etc. I dont want a turbo or BBC. I know that may not be the way to go the absolute fastest, but it's my car and thats the way I am going to do it. Although I do appriciate the insight because alot of people dont know the options they have going into builds.

Yeah this is my plan too. 383 in the 10's. I want to keep the LTx topend too.

 

Gonna be hard, better lighten the car up.....the lighter the car the easier its gonna be.


Good luck guys.

It's not hard to go lower 11's with factory ported LT1 castings but 10's is another story. I have used Lloyd with all my combos and I always run good numbers so his stuff works period. My car ran 11.00@121.8mph on the very first nite out with a loose converter, 355" LT1 engine, LT1intake and LT1 castings. Since then I puit my n2o converter in and the car still ran 11.09@123mph with a bad miss on the 1-2 shift and 2-3 shift so once I get the car dialed in it will run 10.70's or better on motor. So it's hard to argue with results and my car is a streetcar, full exhaust, pumpgas, drag radials, power brakes, 3,450lbs etc...I am going dyno with the LTCC setup next week and then back to the track to see what it will do. Davids car also has Lloyds heads. Later Clint

 

the key is to get parts that work, and work well.

The main problem (that I have noticed) with people going fast, is suspension

Look at ABA383, hes running low 11's on a SMALL cam

 

It's not the main problem...

I do what I do on stock suspension... granted, suspension will help and is on the list, but poorly planned combos are the worst.

 

I think your mildon oil pan makes up for your lack of suspension mods.

 

Definately but suspension is what makes cars really quick, 60' and ET wise so if I had all the suspension, gearing etc.. to cut 1.20 60's like some people my car would run much quicker but I am working on it a little at a time.

 

I am another of the budget rebuilds and thought I would put my .02 in. I have a raceweight now of 3320 with me in the car and 1/4 tank of gas. This is with the interior gutted (still have the door panels on, but thats about it). This is also with no passenger seat, no AC, no sway bars etc. This is with a full size front tire though, which may be next on the list. I was running 12.50s@110 (5400 DA, about a mid-high 11 corrected at about 117-118). This is just with LE1 heads and LE2 cam, stock TB, stock intake untouched, ram air with paper filter etc. I am ready for the nitrous myself, because I woudl rather spend the money there than on a throttle body (which I will probably need eventually anyways), new k-member, or more porting on the heads (which I will also need probably with nitrous). I also have a mail order tune. So no matter how much you do, you will "need" more is I guess what I am saying. Weight does play a big factor though. Just slicks and the weight reduction got me down from a 13.0 to a 12.5 (dont forget, this is at altitude). I will give you guys some new times later this season once my shoulder heals, as I just moved to houston. Shoulder surgery tomorrow morning...great.

Good luck with your build, and do whatever YOU want, not what these people on the form THINK you want. If that is the transmission you have, use it. I know I am about to blow up my t-56 and I personally wouldn't suggest drag racing with a 6speed any more. I used to love manuals, but now I would rather have a drag ready auto. Dont forget a nice driveshaft, driveshaft safety loop, transmission kevlar shatter shield (or something to that effect). Safety first!!

 

....and I'm going to do my damnedest to get a 10.9999 run out of my junk this Spring...I think 121 ish is on the bubble for a 10 second pass. I have since had my Vig restalled to 4000 from 3600 and it feels really good, and I'm going with a Spohn rear drag sway bar to replace my Spohn street bar....I am adding the weight of a 6 point chrome moly roll bar, but I think that if I can get this thing anywhere in the 1.4s in the first 60' it'll get real interesting...and my cam is only a 226/234...and I'm around 3550 raceweight...

I think suspension is a major area thats often overlooked, but again should be done correctly with good parts/setup...

Its been said before everything has to work together...I love my LPE/E.B. Porting heads...I still think LPE has the best LT1 stock casting head out there, but they are pricey...
