What all do i have to do to use a 420a block from a neon on the head off of my avenger????? Need to know as soon as possible thanks

Um take the block out of the neon and the head off your avenger......  ;D

As far as I know you don't need to do anything special.

yup, as long as it is the 420A Block you are good to go.

I thought I remembered seeing somewhere that they won't interchange.  Aren't the heads on the Neon backwards compared to an Avenger, the exhaust comes out the back instead of the front?

The head is on backwards, so you can't use that.  But the block is the same. 

Ahhh, I knew something was backwards with those Neons.

As long as it's a 420a block with your head your good to go...  and yeah, backwards is one way of describing a Neon   ;)

a 420a is a 420a man,  sebring, avenger, eclipse, talon, or the bass ackwards neon (peon)  same motor, same parts.

only the block. a '78 350 is not the same as a '95 350

I've always wondered about the sohc neon 420a will it work? Just curious.

Please refer to the rest of the thread that you apparently neglected to read...





FYI

And the votes are in..............

machine shop is the next step.

Okay, just to be sure, does this mean that aftermarket hi-compression pistons for a Neon will fit the Avenger too? I'm like 99% sure they will, but don't want to buy a set and find out some piddly little thing won't let me use them :( SOHC and DOHC pistons interchange too or no?

ok. the pistons I would be iffy about. In order for a piston to do it's job [compressing the fuel/air mixture inside the cylinder], it must have a cylinder head attached to the block. Since the heads for a neon NEVER should be used on an Avenger or Eclipse, I wouldn't.

You use Utensils to eat food with, but you don't use a fork for soup.

Make sense?

Yeah makes sense, I was thinking that the valve reliefs would be a bit different, since the intake and exhaust valves are reversed.

on a interferance engine like ours, there are little slots in the piston for the valve. Depending on number of valves = slots in the pison. 8v 12v 16v, not sure what the neon is. but i don't think it would work. unless you wanted some valves bent on the piston.
