now now.... its you're not your.....

 

what the hell, how am i an idiot? and no im no local but if i was i wouldn't give your immature *** a chance... just stop, this forum is about mods not arguing and fighting, i mean really, how old are we 13? stop... if your want to criticize go somewhere else... i dont care

 

oh, and just so your kno, unknown, <that meant i was agreeing with you..... i didnt notice it said rollyeyes... but i can get a LT4 hotcam for 100 bux so it would just b worth it for me right now...

 

it didnt finish what i was sayin??... neway the rest of it WAS i didnt notice those were rollyeyes, i was agreeing with you, but the reason i was get the LT4 cam was because im getting a really good deal on it for 100 bux... so yea...

 

when i said about the you got yelled at too, i was talking to 385 not mr dude... just to clarify...

 

Is the LT4 conversion really that great? I know it was better than the LT1's, I just didn't think it was THAT good. Are the LT4 heads better than, say, some AFR's? BTW, there's someone on ebay selling some ported LT4 heads for like $600...i asked him if the were actually LT4's, and he said they were true LT4's! Ported LT4 heads for only $600....this sound like a good deal?

 

Its streetable but its not going to put down the insane numbers that a lot of people think it will.

 

Is there any problem with AFR heads and streeeetability? Would the AFR's put down better #'s and be as streetable as the LT4's?

 

Ok, there is a bunch of BS flying around this thread.


I've got a pieced together LT4 conversion. I've got:

Stock GM LT4 Heads
LT4 Intake
LT4 Hotcam
Heddman Headers

Otherwise stock LT1

I have NOT had it dyno'd, but I can assure you it is NOT putting out 425 hp. right now it's probably closer to 375-380 if I had to guess. Over christmas I'm going to try and get a larger throttle body and get it tuned on the dyno to try and hit 400, don't know how successful it will be.

The LT4 Hotcam is a great street cam. The power range on it is incredible. However, I'm looking for more. It is a good cam, but I want more, specifically more low end torque. I've heard great things about the GM847, might switch to that.

The advantage of the LT4 heads over the LT1's is the port shape. It come factory flowing more and having the ability to be ported more. But when you heavily port a set of LT1 heads and a set of LT4 heads the difference disappears. At max porting, we're talking about probably less than a 10 cfm difference between LT1 and LT4 heads.

On another note, the LT4 intake can be used with LT1 heads, but the LT4 intake cannot be used with LT1 heads.

For the money, the LT4 conversion is one of the best packages you can get and make great power. If I could get good traction I would definitely be running mid to high 12's right now. However, if you plan on doing heavy mods later on or what to run faster than mid 12's, either just get the LT4 heads and intake and get a different cam, or get another package all together. AFR makes awesome LT4 heads that flow some incredible numbers. I also saw a banner on cz28.com the other day for a company that is porting LT4 heads to support 550 rwhp I'm checking into those but they dont have any information on their website yet.

 

found the link.

Race Prep


The banner says "LT1/4 Max velocity heads. 330+ CFM Capable of supporting 550 rwhp."

 

but the LT4 intake cannot be used with LT4 heads.

/\ right there did you mean the LT1 intake? because obviously the LT4 can be used with the LT4, im not being a smartass, u kno me tex, im just clarifying... what are the disadvantages to MAX porting? cost? reliability? are your headers longtubes?

 

Oops, my bad Just went back and fixed it, got in too big of a hurry.

As far as the Race-prep heads, the only disadvantage I can think of is they are going to like the high rpm range for the better flow, so they may not be so great around the lower rpm range used in daily driving. Not saying it would cause problems, just might make it interesting just cruising around town in high gear.

No, my headers are not long tubes, wish they were. I might try and do that some time soon if I get a chance.

 

oh i c, so y don't more people port their heads to the MAX!!!!!?

 

cost vs benifit.


alot of people dont port their own heads. and well, it costs $$ for someone that knows what they are doing to port them for you.

to alot of people, mid 12s is good enough....
you have to have a ending point... otherwise you end up going overkill..... some (i dare say most) people just bolt on the heads without doing anything to them.

 

im just wondering because now that you say my LT1 heads ported to the MAX~!! will b the same i just might do so, but im lookin for the reasons not to... ya kno~!?

 

how much is it? it couldn't be more than the LT4 heads, COULD IT!?!?

 

a question for you also mr dude, what kind of lowering springs did you get, i see it in your little icon but it goes REAL fast... i was thinkin about some intrax and dropping my formula 2", what do you guyz think?
