I liked the Hot Cam setup. mainly because it was not too wild and noisy. I am running the LT 4 heads, 1.94 exhaust., etc.. I originally posted about this setup earlier this year but wound up having to redo it because the original mechanic almost destroyed the motor. After the car started...

Has anyone changed their LT1 setup to the GM Performance LT4 Hot Cam Setup? Though the promos guarantee 425 crank HP,to insure I get there, I am also going with a bigger TB, 58mm vs the 52mm, 32 lb. injectors vs. 24 lb injectors, the Edelbrock LT4 Intake, Hooker Shorties, K&N air filter, .030...

I believe that I did the second option when I sent out the specs on the car about 6 weeks ago. The place I got it from took every new spec of the engine and with all of that, burned the chip that now sits with the stock PROM. The sheet I had my friend / mechanic turn in, was a very thorough...

I got the correct PROM even though it was discontinued by GM. I put it in the car and finally the car makes power from low to high RPM. It is a wild little small block. Ironically I blew a header gasket Friday so even though it feels great, it doesn't sound as sweet as should. Thanks all.! Bob

Well it seems I got a lot of really great information here and I can't thank those who helped me enough. I think after all the advice I received, I found the culprit that keeps the car from achieving it's peak power. Whomever owned the car before me put some Hypertech chip in the car. When the...

Whatever I felt on Wednesday, when I first took it home, is nothng like I felt last night. The car, now with over 400 miles on the engine, sprung to life. I took it on this one road and when I stepped into it on Wednesday night,felt a little more powerful than before. Last night, on the same...

The LT4 has smaller intake valves. 184cc. I can't find the rest of the info but I do know about the intake valves being 11 cc smaller than the heads for the hot cam. Check please, if you do not mind, what the stock LT4 Heads have again. You are right though. The best way to find out is by...

These are the specs on the stock LT4 heads and beneath that are the upgraded LT4 heads for the Hot Cam kit: Cylinder heads: Aluminum, with 185cc intake port volume Combustion chambers: 54.4cc Valves: 1.94 intake/1.50 exhaust Valve spring pressure: 100 lbs. Rocker arms:1.5:1 adjustable...

GM Performance sells, for around $2,750, a package that includes the heads, cam and all the goodies associated with the cam. The heads are a notch or two above the original LT4 heads.

I am using LT4 Hot Cam heads, which are, for lack of a better description, an upgrade from the standard LT4 heads. I chose not to do any work with them because I felt the HP numbers I was promised were right were I wanted to be, not any higher. As I drove it more today and approached 300 miles...

I just finished putting a lot of money into my 93 LT1. I went with an LT4 Hot Cam Kit, including heads, 58mm TB as opposed to stock 52mm, 32 Lb. injectors instead of 24 lb. injectors, Edelbrock LT4 intake, Hooker shorties, Borla cat back exhausts and a K&N air filter and a new chip burned for...

can you put an LS motor in a C4 Car? Is it possible to put an LS 3 motor in a '93 Vette? And if money isn't an object, is an LS 7 aka ZO6 motor somethin that could go in a 93? I want it all ready for spring. I keep hitting dead ends. Bob ;help

I want to replace my stock LT1 with a much stronger and faster motor. I am looking to got from 300 HP to around 450-475 HP. It has to be a motor that works with the computer or else I will be spending a lot of money for nothing. Does anyone know where I can buy a motor like this and what it...

Carlisle is fast approaching. I love going there. It is like Xmas in August for my son and I. How many of you are goign and what is your favorite event at the Car Show? I love the parade. It is like nothing else in the Car World for us. Bob. SO who is going?

Out of curiosity I wanted to find out what a stock 93 LT1 six speed with a set of 3.07 gears out back would do. I found several different results. The most intriguing one said 15.1. I found, on the opposite end of the spectrum, 13.56. I raced my friend's C5 convertible and whipped him...

The sad part though is that GM will give the Cadillac the engine too. Tell me that doesn't really suck!

The one record the new ZR1 will definitely break hands down will be the asking price plus the surcharge no doubt any dealership fortunate enough to get their hands on will add on to the already lofty price. Can we say second mortgage? Bob

One more thing. Nobody can compare the C4 generation ZR1 versus what Chevy will be rolling out in 2009. The new ZR1 will have over 200 more horses, globs of much newer technology, refinements that will blow all of us away and who knows what else? I almost bought a C4 ZR1 but from what I...

When Chevy offers a vehicle that puts out in excess of 600 HP, does it really matter what letter / number designation they give it? I think it is an honor when Chevy feels that ZR1, LT1 should be used on vehicles for perhaps a second or third time. Why would anyone care about an engine / car...

I never saw your message when you asked me where I lived in NYS. I live in Pine Bush NY on the Ulster County side. I see you reside in Kerhonkson. My brother in law lives in Napanoch and my wife used to live in Kerhonkson. My name is Bob and I am sorry I never got to see your post until...
