2.8 rebuild Q?

[OregonXJ]

Hey any one know about how much a top end gasket kit cost's.and also will a holley carb on a edelbrock torquer2 intake make much difference with this engine?

Is it too late to do all those mods to a 3.1/3.4L block instead? The 3.1/3.4s are the latter versions of the 2.8L and are a superior engine in terms of power and reliability (much better oiling passages) and will go in with minimal hassle if you stick with the carb. Run a search on "3.4L swap" and you should find all sorts of good info.
Jeep on!

In short, no. even with a matching cam and a fresh rebuild, the 2.8 w/carb is a slouch. many $$$ and little HP gained.

You wouldn't want to do just the top end anyhow. If you don't do both the bottom end will usually give out if its as worn as the top.

definately go with the 3.1/3.4 conversion. much easier,much better setup.

I can vouch for the previous comment. dont waste your money. go with the updated 3.4 out of a camaro and run your holley 390cfm and edelbrock intake on that. Maybe even some edelbrock headers like i did. You'll love the new found PP/TQ. Check out this link for helpful info on your swap:

The 2.8 on a good day is said to have 110 hp. The 3.4, 160 hp. Still not a ton but much better than the old mill.

I just got done doing the 2.8->3.4 conversion, and it was well worth it. If you have any questions, PM me, or search my topics.

Friend of mine did a 3.4L in his little 80's toyota pu truck that had been converted to a tow truck, that little sob was a rocket with the holley 650 and high riser and pistons and cam and head work. but even before he built the engine out it was no slouch in it's stock form...
