What are the first mods i should do to my LT1 that are the cheapest, easy to do while the engine is out, and what type of heads and cam should i get, should i get the 52mm throttle body, or leave the stock one on... i appreciate your input thanks all...

 

A camshaft, springs, hardened push rods, timing chain and waterpump are great mods. While it's out I would replace the optispark also. Once you start talking about heads the dollars get high.

 

define inexpensive..


how much you have to spend?

 

well, like right now i have like 100.00... but in a week i will have another 300.00 and so on... so i can save but its not like i have 2 or 3 grand.... so i guess no totals over a grand is inexpensive... but yea what kinda camshaft?? and what not... thanx guyz!

 

well if you get $300 a week for the car....... save up a few weeks and buy a LT4 kit.

 

nah, i dont want a LT4, if i did i would have waited to buy one... i would rather mod this one to b better ya kno...

 

ok.

you should get better heads with bigger ports

and a nice high flowing intake to match the big ports

hotter cam

springs for the hotter cam

and roller rockers


should put you around 450+ hp




ps (i hear that someone is selling a kit that will have all that stuff you need, at a cheaper price then if you got it in pieces... all designed to work together and still remain 100% daily driver reliable...)

Who?

 

 

Pace Performance and Summit Racing,

oh, but wait, you don't want to do LT4.....this is only the entire LT4 bolt on.......hmmm.....450hp worth going to LT4 components????

 

Cheap mods are kinda hard too do. If I was trying to save money and make good horsepower, try porting your own LT1 heads and throwing in like a cc306 cam(some matching springs). You'll also need supporting mods for this to make it's full potential power.

People on camaroz28.com are making around 400 rwhp with ported LT1 castings, a big cam and supporting bold on mods

Make sure you have a good exhaust system, some headers would be good, same with a good CAI.

 

ok since you honestly dont seem to know, i'll tell you.



GM does.




the "LT4" kit is just that.


you bolt on the diff heads and intake, put the new cam and rockers on, and thats it


everything you need is in the one kit and its still 100% daily driver reliable.


the LT4 uses the same heads and intake.. hence the name LT4 kit.



dont order thru summit, but order thru either your GM dealer or a wholsale GM dealer like Pace or soggydicky....

 

www.gmpartsdirect.com has a pretty good deal on the LT4 kit too.

 

So what you guyz are telling me is that there are no better heads or cams than what is in the LT4?? because like i said before, i want my engine BETTER than a LT4

 

then your only other option kinda is the AFR alum head...


but in the real world, people have been doing better with porting the LT4 head.......


also, you could always run a diff cam....


trust me... you will be faster then most LS1s with the LT4 kit....

 

you did say inexpensive...and you can pick up a complete LT4 kit from gmpartsdirect for around 2000...and that is a complete kit with heads, cam, intake, gaskets, etc engineered to work together. You'll spend that just on aftermarket heads and a cam kit if you try to outflow that kit.

 

$2091.16, including roller rockers and all gaskets.

 

about how much is it to port heads?
and thanx for your help guyz

 

I know of that...I've seen the LT4 conversion several places, I just didn't know if it was worth it or not. I was thinking of a Nu-Tek 383 stroker kit for around $1500....but I was concerned about driveability. The LT4 conversion is looking pretty good.....especially since I can get a discount on GM parts . Which would be the best bang for the buck....and the most practical? I don't wanna steal your post 90formula5spd....but it seemed like I was wondering some of the same things you were.

 

well, the lt4 kit puts down a dyno-proven 425-435 horses, i just like how it takes the guesswork out of it.
btw, had the LT4 kit on my 94 formula, night-and-day difference. It was awesome.

 

Do you have any more specs on your LT4 conversion? I just bought a powdercoated LT1 intake off ebay, but that is when I wanted to do the 383 route. If there any way to convert an LT1 intake to use on LT4 heads?

 

Port design is different on the LT4 setup, i think the port roof is higher, so i don't think the LT1 intake will work at all. not sure of the other differences.

 

Yeah, LT4 heads have a higher intake port so the LT1 intake won't bolt up to LT4 heads. They flow better too and I thinkn the valves are bigger. LT4 conversion kit would definitely be worth it....provided you could hook up. And if that isn't enough, put in a bigger cam or throw some boost on it.

 

from what i hear the LT4 heads and intake are about the best way to go, but if your looking for a lot of power you might want to upgrade the cam, BTW does the kit include the LT4 cam, or the LT4 hot cam? i have a LT4 cam, haven't installed it yet, but for a lot of power i'd say go bigger. rumor has it the LT4 cam is a good mid sized cam with great streetability, no stall is needed, but a 2800 is a LOT of fun with it

 

the kit comes with the LT4 HOT CAM, with 1.6 roller rockers, heads, intake, springs, retainers, basically everything to turn a short block LT1 into a long block LT4. I agree that the LT4 HOT CAM is a good midsize cam with nice street manners.....but it is NOT a weak cam. They pull really nicely in the upper RPM's. I'd stick with this if you want a fast every day driver. Definitely throw that 2800 stall on there and you'd be pretty much set with the fun factor.

 

hey matt dont worry about it man, it is here for everyone who has questions, and christ you guyz sure have swayed me towards that LT4... What kind of discount do you get matt, you lucky bastard! I think i might go with that kit, but it will be a while b4 i get it, because thats alot of money, hey matt you should give me a discount! Neway thanks for all the help so far guyz... keep going, i love reading about this kind of ****@!

 

I was checking out the LT4 conversion kits and stuff and i guess there is problems with the compression ratio because the LT4 has different pistons? Is that true? Does this matter? And you guys really think this is the most cost effective method of boosting my HP? Do these kits come with the timing chains?

 

what kind of problems? i had no problems with my LT1 after i converted it, the kit exceeded my expectations. The kit on gmpartsdirect.com doesn't come with the timing chain, but they do reccommend replacing it with the extreme duty chain.

 

no clue, i just read there could be problems because of the compression difference, but hell mayb that guy had no idea what the hell he was talking about...

 

alright, now how much hp would i gain from a hotcam, and stock ported aluminum heads? i figure this would be a little cheaper and should shut me up until i can get enuf money for that LT4 kit...

 

Well, since I already have a powdercoated LT1 intake..it looks purdy , I'll probably have to go with some non-LT4 heads.....But in Year One they have LT4 heads that they say are a direct bolt on to an LT1. Anyone know anything about these?? They also have some CNC ported LT1 heads. They say something about a $900 core charge not included in the $1700 price. Does that mean that if I send in my stock LT1 heads, they'll take $900 off the price of a pair of ported heads? Which would be better for performance?....the LT4, or CNC ported LT1?

 

OK, well I know year one is a parts dealer for classics, ya know the muscle cars. That being said, you should know that there was a production LT1 in the 70's second generation camaros. So make sure they are talking about the Gen II LT1 heads and not the Gen I LT1....they are way different.

 

not sure of the exact heads you're talking about. just be sure they're the GenII and not LT-1 GenI heads

you pay them $1700 + $900... when you ship them your old heads, they give you $900 back.

better for performance? that im not positive on, but i would think the LT4 head has alot more potential. the ports are larger and a diffrent shape... the taller ports just gives everything a straighter shot...

 

why did you buy the powdercoated intake in the first place unless you were sure about what you wanted to do? your mistake man, but if i were you and had that kinda money i would just resell that intake on ebay and buy the LT4 package...

 

if it looks that nice, it should sell easily on ebay anyway......

plus im 80% sure the LT4 one comes red anyway......

Are those the stock LT4 heads, ya think? Or LT4 type heads that will work on the LT1 manifold? Sorry to sound so troublesome.

 

that site was just yearone.com menus... i dunno what your talkin about

 

This is what hes talking about

http://yearone.com/serverfiles/headline.asp?hid=G12AI78

 

what makes them LT4 heads is the port design. That's where the major imporvement is. If they designed it around the LT1 manifold, they would be LT1 heads.

 

I despise the LT4 cam, mostly because people who look solely at lift when looking at camshafts look at it's lift with 1.6 rockers and think "wow, thats the perfect cam for a street/strip car"

 

 

There are way, way better cams out there. The LT4 cam doesnt have much more duration than the cam that came in my stock 350HO (330 horse, 380 torque), and at least that cam was ground on a more aggressive lobe center.

 

i guess were dead wrong in here too guys....

sorry to break it to ya.... this is a third gen only site... NO 4TH GEN INFO OR TOPICS.....

ya... i got yelled at too...

 

*shrug*

mods are dicks who dont read the whole thread but delete/lock it anyway somtimes.........


happened to me before too...


anyhoo this LT1 is in a 3rdgen, so its a "legal" topic...

 

what the hell are you talking about? this isnt third gen topic? man your dumb looks like your the one who didnt read the whole thing... it is in a 90!!! formula, AND it is in the engine swap forum... so your saying since a 406 or a 454 doesnt come in a thirdgen, EVEN tho there is a engine swap forum, it isnt thirdgen related? man you are dumb just shut up...

 

hint to why hes been posting that in every 4thgen like topic:

https://www.thirdgen.org/techbb2/sho...hreadid=209042

hes pissed and thinks taht this would help

 

haha jackass, NEWAY you mentioned you got yelled at TOO? i never got yelled at! the mods dont have a problem with me, nor anyone who isn't a dumbass for that matter... if you post about an engine swap into a third gen car on the engine swap forum, they wont do anything because im not doing nething wrong, you dont need to try to start trouble on my forum, a s s h o l e...

 

**** OFF...... lick my nuts

are you local to me...... i hope so, so i can swing by and kick your ***.

 

Your an idiot.
