383 with Eddy heads!

Now, that sound like a fun ride. Looked at the Comp. specs and they are close. I would think with the Eddy heads and a good cleanup could easily use the extra lift, so i vote for the 275HL. A true 25/2800 converter with a good advance curve and a carb that's not too big, maybe 750ish should give you decent drivability even with that weight and would still really roll when you turn it lose. Just one opinion, hope you get some more. In the mean time, have fun with that 318. Good luck to ya. :thumleft:

Sorry i missed the 750dp in your list. Don't discount a 750 vac. secd. When they are tuned properly can still perform
and might actually help in launching a fairly heavy vehicle.
