How Big can a 5.2 get?

Thats what I thought and decided not to stroke. I want decent street manners and best possible gas mileage, RON 98 is 1,50€/ litre here, that means its 6,50$/ gallon :D I also decided to feed the engine with Pro-Flo4 fuel injection to support those things. Engine is slowly getting somewhere, next thing to do is to measure piston to head clearance, pistons are sticking .018" up from the hole so with Fel-Pro 8553 gaskets I should get Quench around .035".

Wow, fuel prices here are literally one-third of that, fuel station near my house has 91-octane (RON+MON)/2 for I think $2.25/gallon? Even still I'm happy my engine will only be 9:1 compression I should be able to run 85-octane regular gas or at the very least 87-octane midgrade. Too bad I can't ship you a barrel of cheap American gas :lol:

With good quench and compression like you're building for, those heads which have good air velocity esp. with the smaller intake valve, and the Hughes roller cam, I bet that engine will run great at all speeds and have a nice fat torque curve for the relatively small displacement.
