i'm a TPI guy not a TBI guy, so my ignorance is gonna really glare here, but i'm just trying to learn more about you guys. i see that you guys really like LT1 cams. what is the deal? do you actually have enough intake and heads and exhaust for this? an lt1 is a high revvin motor, normally a TBI is not. and yes i know the same would apply for me too. tpi motors fall on their face at high revs too. lots of guys on the tpi board run lt4 hot cams too. just wonderin about you tbi guys

Yes, I used the LT4 Hotcam and It made me make power much higher. Of course, I did use the stock heads, but I ported them, and polished them. So I could see 5800 rpm easily.

But....sigh....I had to take my cam out and my gears, and I put back every stock option. I just couldn't afford the gas. Just because of yesterday, I've seen gas stations raise their prices to over 2 bucks a gallon. I'm sure glad I took my mods out a few weeks ago. It's now bone stock, and all my parts are sitting in my house. Now it's slow as heck.

Now my car runs good, and is a gas sipper. I don't like the looks of 2$ a gallon, I fill up every week and a half now. Before, I had to fill up every day and a half or so. It was that bad.

Well, I am buying a 1986 Regal beater for 200 bucks to drive around, then I'm doing the DZ-302 swap with a T-56 and a Ford 9" with 3.73 gears in my beloved Formula.

I hope the prices go down.

welcome. tbi doesnt restrict our engines the heads and cam do. by changing the cam and or rockers we can make more out of our heads. with porting i beleive our little l03's and such are capable of going to 6k. read the stock l03 cam specs, then you will really understand why people are hot on those lt1 cams.

yah i guess in terms of useable rpm a TB is no different than a carb. tpi is what falls on its face at high rpm cuz we have long runners. thanks for the enlightenment. i try to keep a well rounded knowledge base. i actually bought a sport compact car magazine the other day to check out the latest on the turbo guys. and learn more about some of the electronics they are using to optimize their combinations. i hate ricers, but the few guys that actually have the knowledge to do that stuff themselves i totally respect. a fast car is a fast car, no matter whose name is on it.

ws6formula would you think of selling the hotcam?? if so how much?

I'm not selling any of my parts.

Hey, after all of this tragedy is done with, I might want to put the stuff back in.

But I am building a 302 for high revs. I still need to find a 283 Crankshaft. I can get a hold of a 4" bore engine block. I'm mating it to a T56, then re-using my aluminum driveshaft. It's all going into a Ford 9" with 3.73 gears. I'm going to make the suspension better.

Really, I paid 250 bucks for my cam, and if I sold it, I would be losing money. I just best not sell it. 50 bucks is usually what it runs for a used cam. I can't take the loss.

Like I said, I'm getting a beater Regal to drive until I get my car perfected. Oh, you bet it's going to be perfect.

-ws6formula-

dude a 302 will want gear way higher than 3.73. More like 4.30, 4.58, 4.88.

3.73 should be plenty...

Well, it could WANT 4.88 gears, but it's not getting them.

I might run 4.11 gears since for the simple fact that I will run a T56. I want traction too, that's why I'm thinking 3.73s are perfect. It's not like a 302 is a TORQUE-LESS motor, it just needs some added help. 3.73s are good if I want good traction.

-Todd-

when GM made soem test 302 LT1s, the 4thgen had 4.56s and the 1stgen had 4.88s. New high reving DOHC cobra's love 4.30s with their T45, just as some comparisons.
-Tas

I think I will go 4.30 gears if I get a T56. Now that you mention it, I do recall them making a new 302 Camaro, I saw it on www.camaroz28.com I think.

I don't know, I want the best traction, since this is just going to be a cruisemobile, and see the strip frequently. It's going to be a show car too.

I'm still buying that 84 T/A with my friend, and we are going to try to get that into the 16s. That is only 800 bucks. I am still buying that 86 Regal though. But only because he is one of my Christian friends, and he just got a GTC LeBaron.

We budget minded TBI owners are taking advantage of the "trickle down" effect. Someone with a LT1 upgrades to a LT4 hot cam or some other superior cam leaving them with parts they no longer need. Their trash is our treasure. We pay 1/4th what a new cam would otherwise cost and they get a little cash towards their next mod. Oh yeah, I have a high performance "Peanut" cam for sale cheap. Keep the economy going!

It's just a great cam for our cars. Considering the poor lift and whatnot on the stock LO3 cam, you can see why. I myself got a LT1 cam out of a 1996 Corvette. The cam was supposedly taken out immediatley for a hotter cam, I dunno...though it was in EXCELLENT condition when I got it for 40 bucks. Like someone else said...the throttle body injection isn't the problem, it's the crap heads and cam.

S I've thought about a 302 build up for my 91 Caprice. It's got the L03 also. But the car weighs too much and the 700R4 doesn't like to rev over 6k too much.

It would be really easy to build a 302 LT1. The (LT1/4) 350 block has the 4" bore and the (L99) 265 (nodular iron) crank is right at 3 inches. IIRC, this crank would work in any late style block.

a 302 is the last thing a Capriece needs. I'd put a 383 or 400 in that monster.

I agree. It depends on the $$$ I can get together for this. It'll either get a 383 or a 454

ws6, you want to use a 87 or later roller block with the one piece rear main seal then use the L99(265ci) crank and rods(5.95")and 350 pistons. It will all bolt right in. A set of good heads and your hot cam sould wake this thing up.

I'm probably going solid roller for the cam. As for getting a L99 crank out of an actual 265? I think it will be very hard to find a 283, let alone a 265 to rob the crank from. Unless you guys can grab me a L99 crank new, I dunno. I'm not using this as a daily driver...

I think a 302 LT1 is a very good idea! I think I might do that! I didn't think to do that, but I am definitely interested in that swap now.

I just want a 10k revvin monster, and I don't think hyd. tappets are going to get me there. The original DZ was solid flats, but I think I can get away with using a solid roller.

More help is appreciated. Thanks for the info guys!

L99 crank should be easy to find. No one wants them.

The only vehicle the L99 came in was the 94-96 Caprice. And many of those got the LT1. Try GMForums.com and ImpalaSSforum.com for L99 people who are switching to LT1 power.
