I am looking at building a 2nd gen 'runner engine. The beast weighs in at over a thousand more pounds than my 85 runner. The trickey part is not doing an engine swap of any kind, though a 4.3 would be sooo nice. Anyway, if the money was there, what would you do???

Masteryotason, what cfm increase would there be with the ported/polished plenum and runners be on average? Is this going to benefit my torque at all or strictly hp? What about the LC stroker kit, this would help on the bottom end I think, but how does it effect reliability? HELP!!

P & P is mostly for top end!! Desert, Mud runner, on a rock crawler not much advantage. <IMG SRC="smilies/usa.gif" border="0"> <IMG SRC="smilies/usa.gif" border="0">

power shmower, its all about the gears, id concentrate on making it as reliable as possible, meaning dont mess with it unless its broke

He's right, port & polish is top-end style stuff... which might help on the street for it some. If you want torque, you can't go wrong with a stroker - undersquare (stroke longer than bore is wide) engines tend to be torquey.

A good intake and ehxaust system is definitely in order, as well. Go with an RV-style cam for torque, and either a doug throley or LC engineering header. I've always felt the Thorley (Tri-Y) design produces low-end torque a little better than a 4-into-1 setup.

An RV-style cam (I'll probably go with the DOA C-270) will produce torque - picking a more racing-oriented cam will result in good high-end power at the expense of low-end grunt.

Get some good metal backed timing chain guides, and do a quality rebuild to the engine (which you'd pretty much want to do if you were pulling the engine apart to stroke it anyway.)

Go talk to someone who REALLY knows the 22RE. Spend some time on the phone with someone like Tim at DOA and tell him what you want from the engine and how you'll use the rig. He knows more about 22REs than probably the rest of us put together.</font>

Hell, just by a DOA motor.
