I see that Titan has a 4.0 stroked to 4.9 that makes 315 hp and 345 ft/lbs torque! Only $500 more than the Golen 4.6. Haven't heard or read much about Titan engines though...

If you see Hobbes, tell him I said "Hi".

From researching the sites, it doesn't make sense why someone wouldn't go for the 4.6 or 4.7. But I'd also upgrade the Throttle Body plus you have to remap the ECU. Wonder about the ramifications of emissions testing.

Anyone know what a Jeep dealer sells a new shortblock/longblock for?

Well, if you got a Golden engine, it needs to run on 91 octane and we all know what kind of fuel milage Jeeps get. I don't know what the other manufacturers demand for octane in their strokers though.

I'd rather build a poor man's 4.5L stroker.

Edit: I just called Titan Engines to see, and their stroker engines also require 91. He did tell me though that their 4.9L stroker engine can run on any fuel because they can build them with adjustable compression.... but the HP/TQ numbers will be lower, of course.

94 YJ w/ stuff. All the work/money I put into it, and the comment I get most is my $20 mod: "Hand throttle?!? That's awesome."
