Title: 520 inch MEL
Post by: Royce on May 27, 2023, 08:15:12 PM
My final MEL build..
462 Block, offset ground stock crank. Scat rods, Ross Pistons, Performer RPM intake adapted from a 385 series.  Joe Craine ported heads,  215/177 valves.. Custom hydraulic roller from Comp..9.5 compression. Distributors are getting hard to find so I used an old Mallory dual point. Holley 800 carb.. I limited the RPM to 5500, since it was an all stock valve train.  Cranked out some real impressive torque. Sold the engine to a guy in Boston.. Kinda wish I had kept it

Royce, why do you say "final"?
That torque curve is pretty impressive. Looks like it would make an excellent towing engine if it could stand a regular fuel diet. Or something that could fry tires without straining anything. Did you keep the dual points or convert it to electronic?

Final, because I sold all my MEL engines and parts to a guy in Boston, And I have moved on from my MEL phase lol.. I wish I would have had the dyno guy pull it down to 3000 to find peak toque..   It would probably run on pump gas.. I was surprised by the torque.. It makes approx 30 more horsepower vs a few yrs ago when I dynoed it with a flat tappet cam..

      That's why they were nicknamed the "Bulldozer"!   :)

      I'm guessing you turned the stock cast crank to BBC 2.200" or.............?   :-\

Yes  ended up with a 4.21. stroke  Scary if you think about it.  lot of meat removed. Another reason to limit it to 5500
