Hi warmride,
VP is right I am getting a 327AL. This is a 410HP engine, but it's replacement is the 327R, which has about 420HP and a dart block with everything in the crank etc forged, both have the bottom end girdle etc. The motors are warranted for 2 years and 40,000 klms and are warm run on their dyno's first and they send you your dyno spec sheet (50 dyno's at Roush!), somehow I don't think it would need pulling down first or suffer from Monday-itis or Friday-itis. Their engines go from 350-1050HP, I'd call to see if you could negotiate a deal on something that suits you, it worked for me. If so, that might bridge some of the cost gap. I guess if you stay away from some of the trick pieces like fuel injection and serpentine belts etc, you can keep the cost to a reasonable minimum. I always wanted a polished engine but wasn't going to pay the extra, but as luck had it the 327AL was being discontinued and the stock they had left were all polished, sometimes the stars line-up, but as you know, not often!
Yep, now 427 does sound pretty cool doesn't it...............good luck
Cheers Bee
