My car is finally running! with a rebuildt 4.2!
It took forever and it's long story so i'll just summarize
I was without a car for the whole summer though and we spent more money than expected.
We had a 1997 4.2 block sitting in the garage with a cracked head and two bent connecting rods.
We did an almost complete rebuild the only things that we reused are the 4 connecting rods, the crank and the 4.2's camshaft which is suppose to be better than 3.8's.
The 1st time we bought ****ty pistons that messed up the engine. So we had to rebuild it AGAIN!
thankfully we got new stuff for free since it wasn't are fault.(later we ended up buying a different brand since the ones they sent us sucked)
We had to get the block bored since it was scratched pretty deep from the last pistons. We went 30 over on it.
Then we got it running yesterday and I can feel the power difference.
We also did the little air silencer remover mod. I don't know if that made a power difference since we did everything all at once.
I also re-used the single port head's which I read has a slightly higher compression, still runs fine with the old gas that's been sitting in the tank for 3+ months.
Does anyone have any HP and Torque estimates for this?
I was thinking 180hp but I don't know about the torque.
