[ryanfay]

They did. For bayliner.

Does it match your block?
Rear thrust or Center thrust?

[bearman683]

it says it fits b230f/b234f block but will check thx

[ryanfay]

Stock rods. pistons different.

Yeah, there's 2-different types of b230f blocks. Different sized main bearings, and different type of thrust bearing.

[bearman683]

he also has rods and pistons for it and says it is supposed to fit b230 block. the b234f is a dry sumped duel cammed b230 so it should work. I wonder how much hp it will make the pistons are dished and valve relieved cut already for b234f head already and is 10:1 compression do you think rods would hold up to turbo app?

[bearman683]

will check bearing size and thrust bearing size.it is a rear thrust bearing type

just got off with seller he builds volvo motors all the time and sell parts to car guys all the time for this same swap and is 100% sure of fitment

Don't spout tired worn out clichés without thinking..

Of course there is a replacement for displacement silly bastid.
Its called BOOST..mechanically pumping in more what?

Cubic feet of air, otherwise know as volume. Displacmemt..
The Volvo 86mm stroke cranks return about 7% increase in engine volume..

For most people its easier top just turn up the boost so that much more are gets shoved in..

Do you own a set of cheezy electronic calipers? You should.
Measure main journal..is it 55mm..then its the small journal B230..Not bad really just ALL the professional engine builders here, and everybody is, sneer at those..
So what block and what main journal dia?

The crank fits either in a '85-'88 b230 or in a '89+ engine. Or it must be an elastic crank.

[bearman683]

that year has what size main journals 85-88 then 89+ let me know thx

[bearman683]

it fits a 87 block I'm out of luck I guess if I understand the info correctly am I right?

[bearman683]

more room for more air equals more hp that's the truth, you can only fit so much air in a certain amount of space so add more space=more potential power output!

[bearman683]

so what's the difference between the b230ft and the b234f excluding turbo/16v head respectively? one is wet sump one is a dry sump, one has external drive oil pump,one internal, one has balance shafts the other doesn't one has as interference head one doesn't each has it's pro's & cons both can be modified for power. That's why there is different options for an engine build. I have a b234f so I choose to build it if I had another engine I would build that.

[Harlard]

The blocks are not the same. Also, the 16v car engines had a windage tray, not a dry sump. Look at dry sumps. Very different.

[bearman683]

ya thats a better set up

[bearman683]

they share the same crankshaft though

[bearman683]

they share the same crankshaft don't they?

What do you actually think wet and dry sump mean? Do you know the differences?
