Compression & Displacement Increase ?

Forum: I notice that most forum members want more low rpm grunt.
On many engines an overbore to increase displacement.
As well as decking the block and possibly milling the heads to increase compression.
Should improve performance at all rpms?
A little porting on the heads can't hurt!
Am I missing something, is this not feasible?

I'm thinking of an engine that already needs to come apart. lol

Check this out, some are already doing what you may be looking for.

Supercharger will give you some grunt, Turbo is pretty good at top end. Or do both.

 

Missed the stroker kit group buy, by juuuuuust that much. There is a stroker kit for sale from another member though.

Do not mill the heads unless they are damaged. Otherwise you're taking away material that may potentially be necessary to prevent throwing a head away, in the future.

Just get increased compression pistons.

If you want to over bore, then you will want to sleeve the engine with Darton Sleeves. Plain and simple.

Brian Crower has nearly all of the parts that you need.

 

what year engine & truck

the engine control module ' ECM ' may not allow any real gains as it will default to orig settings unless U ' ReFlash ' !!!!!!
