L67 rebuild considerations

**02Prix** · 05-09-2011

Hello all,
I have a 98 gtp with over 200k on it, the whole care is in very bad shape but it has a decent running motor and a operational tranny. Not bad for the $100 investment. What i want to do with it is a complete engine teardown and rebuild so that i can have some solid ponies to put into my 2002 GT. Im not sure what i will have to do with the transmission i would like to keep the 02 tranny if possible but i do not know if the electrical will jive. At this point im just getting ready to pull the motor out of the donor car. I plan on sticking 5-7k into this motor after the rebuild and prolly a pcm tune. I want a better than new motor and plan on doing as much of the work on my own as possible. So far i think im going to make a valley pan, replace the oil pump, balance/polish the rods and crank prolly look into getting new rockers and at least grind the valves. Im not sure which rebuild "kit" i want to buy but everything mechanical needs to be in the like new or new condition. Other than that im not really sure where i want to go with this. I plan on making this one of those longer term learning projects. i have done hours of reading on this motor and i know there are many many possibilities for this motor, hoping some of you guys can get me pointed in the right direction.
Thanks in advance,

you're wasting your time. if the motor runs fine you're just wasting money.

The l67 runs decent, as in i would not be afraid to drive it to work. It does not run good, but it runs. I also know this car had the living **** rodded out of it and it was ran OUT of oil at least once by the previous owner. I want a motor with plenty of power that i can trust driving across the country, not the county. As far as im concerned it will get a fresh breath of life even if its just the plain jane standard rebuild. But since im already going to spend the time i want it to be bigger, better, and faster.

if you find a place that sells factory replacement connecting rod bolts, let me know. if you're just rebuilding it, you probably won't touch 5k. if i could find new bolts, i could get gaskets and rebuild a stock motor for roughly 1500. if you have 5k to spend, just drop it off at a machine shop and tell them to make it new again. everything comes back clean, balanced, and practically new. have your heads ported, run a bigger cam/stronger springs/double roller timing set and an intercooler. or don't intercool, and spend what you have left on a new transmission. and then you're close to 7k... maybe. and you're running 11's

I don`t know what you mean by:"and you're running 11's".

A fair number of us try to make are cars quick in the quarter mile.

If you want to rebuild, it will cost you at least a grand.

Or more.

And while its apart you might as well upgrade things.

Then your stock transmission won't be happy.

I'd just swap the motor in and enjoy it while it lasts.
