I know that a 350 can be stroked to a 383, but can it be stroked further then that?

Also how much horsepower & torque can be sucked out of the engine naturally aspired? No particular budget. Money & emissions are not a issue.

The current engine is a 350 out of a 92 caprice squad car. It replaced my L03 that came stock.

 

You can bore it 0.60 over it will be a 388 not sure how much more power.I think thats about it.

 

you can do a longer stroke crank 3.875 instead of a 3.75. 396ci would be the result.

 

i have a 4" stroke, but it requires a bit more clearancing.

 

Money is about the only limiting factor. Okay and the necessary room to swing a 4 inch + crank. 60 over and a 3.875 crank with some 6 inch rods would be a sweet set up.

 

I think it's difficult to do more than a 3.75" stroke. I think the 3.85 or 3.875" involves a lot more grinding on the oil rails, and other spots. The 4" I really didn't think is possible in a stock block. I thought you typically hit water by then. So, perhaps a short fill first?

86TA?

Also, over the 3.75" stroke, pistons are harder to find, more expensive, selection is less, and/or you need custom pistons.

It's not really a good financial decision to pay big bucks to get a long stroke crank (more $), custom pistons, etc etc, then use a junkyard 350. Might as well spend your cash on getting the 400 block in the first place, then you don't need custom parts. It'd cost less in the end, and you'd have more cubes.

 

its sitting in my garage, stock roller block and 4" stroke built by T and L engine development out of NC, warranty and everything. No fill as far as i know.
