Well, sell the 4.0 on Craigslist...tell 'em they can hear it run. Then take the money and get what will "Slip right in" to your car. I've pulled this stunt before...
Everything is jumping up. Real glad I bought my 360 pistons (JE's) last summer and my Mahle's for my Buick last fall. Energy price jumps make all prices jump, and then demand for non-essentials falls. Can't wait to see what this summer brings with $5+ a gallon fuel...
