Re: Marine Stroker 383
That's Pretty close to what I'm spending on Mine,......<br /><br />.030 over with the 3 3/4" stroke yields 383cid,.....<br />.060 over will yield 389cid.......<br /><br />About Any SBC will take a .030 overbore,.....<br />Some SBCs will Not take a .060 overbore,.......<br />It's got to do with Core Shift,... It happens in the casting process,... The cooling voids end up Many thousandths from where they're Supposed to be,.. Hence Thin Cylinder Walls......<br /><br />Considering the fact that a 350 Block can be had for anywhere between, Nothing,+ $100.00,.......<br />There's just No Way, I'd overbore a 20 Year Old Saltwater Block, .060................<br />I think you'll be asking for Troubles......<br />There are 3 Machine Shops in my area,.... You'd be hard pressed to convince Any 1 of them to overbore a block .060.... Not without a Sonic Test to determine whether there's enough metal for it........<br />And these are Antifreeze blocks out of Autos,...... Not a 20 Year Old Saltwater block........<br /><br />As for the Carb.,.... <br />I'm a Carter Clone kind of Guy,......<br />The Merc./Weber/Edlebrock/Carter Carb.s in the Smaller size, 600/650cfm, Also have Smaller venturis for the primaries,.. just like the rochester does,....<br />Old Rottenchesters are Many times Not Rebuildable,.... The bodies wear out around the throttleshafts,..... Then you've got to ream them out,+ rebush the body,......<br />Why,..???......<br />The Edlebrock can be bought Brand New,... For less than the Labor Bill on the rottenchester's Rebuild,...............
<br />BTW,....... The Carter Clones will bolt to Any manifold,.........
