How Big can a 5.2 get?

Dusterfreak said
I was looking for a 5.9 but those are rare here in finland, pickn pulls were asking 1500€, its almost 1800$ :D
I was thinking about stroking, but that includes 0.030 overbore also and a 2000$ plus freight plus taxes so ill be in 3000$ then...

Hi. Your in Finland ?? 2 options: 1 isn't a 'Magnum' Block but Scrounge around for a wornout 240 or 250hp Chrysler Marine Sterndrive engine: its a thick bore/casting H/duty Block with ALL the goodies ( & I mean ALL the factory H/duty goodies: bushed/floating small end ",Truck/Industrial Rods High Pressure oilpump, 273ci Commando Single Plane 4bbl Intake , big 4bbl AFB, STEEL crank, etc etc) OR if some Intl freight isn't out if your Budget there's an Engineering Business in Australia that makes Custom overbore size pistons with pins & rings supplied.
JP Engineering try google jpengineering.com or jpengineering.co.au I know the owner Laurie - Tell him Trev from NZ sent you. He'll make you Std +080" block savers or any feasable overbore req.
I read in a Hotrod mag Magmun blocks didn't like much over +030"_ +040 without sonic testing & your pushing it: Suggest a Welded up offset ground Stroker Crank done locally with a Custom Compression height piston to match: +.060" 318 takes you to 327cubes, did 1 with smooth flattops: not valve reliefs & pocket ported heads & that was a Stormer , IF you find an ex Chrysler Marine they've also got a high torque H/duty Starter Motor, which is a cheap way to get something to swing the project over + save those Intl EBay type Shipping costs :-/
Goodluck .Trev
