The quote below is from another thread about 351w lightnings. According to Sal Manella, the 94-95 lightning blocks although roller ready, did not come with roller cam, I wonder why? (COnsidering the standard engines did)

"If the $3k is for a COMPLETE Gen 1 Lightning motor (with heads, intakes, etc), than that's not too bad a price, for such a low mile motor. If it's $3k for just the short block, then it's definitely not worth it. The Lightning 351 is a great motor, I've made well over 600hp on stock short block trucks. The heads are just standard issue IRON GT-40s. The lower intake is 5.8 GT-40 and the upper is the tubular GT-40. The throttle body is the FMS 65mm. That motor was basically built using parts right out of the Motorsport book back in the day.
As for the roller issue, no Gen 1 Lightning motor cam with a roller cam, but most 94 and all 95 blocks were roller ready. That means they have the tall lifter bosses and tapped valley for the spider bolts. Look for the F4TZ casting for the roller block."
Were the blocks mentioned above (93-95) retrofitted to roller (an easy retro if the quote above is correct as all you'd need is the roller lifters and the spider/dog bones--no machining necessary if he's right) I'm thinking about getting another block myself, to build a radical stroker with, it'd be nice to know exactly, for sure which blocks have rollers in them without having to open them up.
