Anyone know if there is a way to figure out info on Mega blocks? Things like when was it made, how did it leave mopar (complete crate engine or bare block), orig bore size, ect,ect? Could it be a World Products block? How to tell the difference? How to understand markings on block? What time frame were they produced?
I recently was able to purchase what I believe is a Mopar Mega block that was supposedly a 500 ci crate engine (4.380 bore, 4.150 stroke) w/ stage 6 alum heads, hyd cam and a M1 intake. Although it is still 500 ci, pistons have been changed from cast to forged Wisco, heads long ago changed to Indy SR's (which I didn't purchase, all I got was block & rotating assembly). Block looks good, pistons look good, MP crank is probably going in the scrap pile (damage is repairable, but not much positive going for it) & one of the Eagle rods had a bearing spun.
Any info appriceated. Thanks, Brian
