I posted originally in the wrong forum.



I just purchased a 89 2 door for my project. It's in excellent shape with no rust. I have a 02 4.8 Chevy. engine lined up, along with a 4L60 and trans. case. Will use a 8.8 373 Ford rear end.

I have supper fabricator to help me with the project. I feel I have that part under some control.

I'm looking forward to getting your advice, and thinking to help me along. I belong to the Corvette forum and have contributed and gained information from knowledgeable people.

Thank you all in advance for any advice you may have.

I took the following Pics. tonight after we picked the engine and rear end up.

New Engine


8.8 rear end.

Just curious why some one would replace one of the most reliable engines ever built for something that is not so much??????

If you must this page will help.

Your curiosity as to why informs me your knowledge on the subject deserves a answer that hopefully will inform you.

Better gas mileage, 18-23 mpg originally, I'm planning on at least a 25% improvement. the 02 4.8 engine weighs less, more power and torque, environmentally cleaner, and a superior engine in every way. The engine was tired and would have cost as much as I paid for the new engine [$ 500.00]. Since I don't work, and came from a background that afforded me the confidence that I could do anything I put my mind to, why not.

I am familiar with Novak and purchased his motor mounts recently.

Thank you for your interest.

i was wondering why a 4.8 not a 5.3... they run the same $$$$ for the most part.. as for reliable.. i love my 4.0s but i see those ls engines all the time and they NEVER have mechanical failures... they are the standard to which all new engines are measured to imho... 200k is not uncommon

 

I would say absolutely if you have the knowledge and will power to do it then why not! And all though I love the 4.0's the 4.8's are amazing and are capable of more hp..are you sure it will fit without any major problems?

 

Because more is better. Lots of ppl do te v-8 swap, but I agree I would have done the 5.3, or to be honest the 6.0.

wanna ship me the pressure bottle and a few other parts lol!

 

I would like to do this to my trail rig in the future. Great job man makes me drool.

 

Thank you both Serious of Road and Brookhart, the Naxja thread is great. I keep re. reading it to get all the information. If I had done this much in school I would have been an A student.

Is Frank Z still around, he covered everything.

I do know my 4.8 intake is a little higher. Several have mentioned the use of a 5.3, the engine is I understand is good, but heaver and I think Iron heads, and doesn't get as good mpg. The HP diff is almost the same as is the torque. $500.00 was a big reason.

I may have missed this but maybe it's assumed he lifted the truck. I'm looking at raising it enough to clear. 2"-4" lift should do it, if he did the same, or more, I've got some work to do.

This is why a forum is so valuable, especially once you get rid of the mentally challenged, and the negative individuals.

In 04 I bought a junk yard dog Corvette, it was in boxes and I was able to to make it into a great project and bring it to a successful conclusion. I shared my experiences with others to help, which included a T-5 speed from a late model Trans Am.

SeriousOffroad = FrankZ

 

Mind=blown lol

 

seems like alot of work...why not do like a 4bt or something?

 

Have you looked at the weight of a 4bt?

Dropping a Vortec motor in is simple if you do your homework and don't half-*** it.

And it can easily pass emissions with a little extra effort.

 

I'm in love. This will be the next step when I get tired of the small block.
