221 turned out to be a 188

[KEWL65]

Bought a 221 for my XP wagon and it turned out to be a 188 .

I am currently considering whether I try and buy a 221 or rebuild the 188. I've got a 2v head to go on the block.

What are my options for the 188 other than using it as a boat anchor? What can be done with these motors or am I wasting my time with it?

mate if your after powaaarr, i'd go and get a 250 for that 2v head, if not a 221. i cant see you getting much power for money spent out of the 188 if power is a priority. Depends what your needs are.

Is it a 221 block?

Wondering where you might be with a 221 crank and the low crown height ACL pistons on 188 rods.

Addo the numbers are ARCDE6015. The crank has 188 stamped on it, the rods are 5.4" and the pistons are dished.

Just wondering whether building a 188 with a 2v head is worth the trouble?

Heck yes! They're all over Argentina. The real "catch" is you'll need to build it for RPM higher than typical for a 250 or 221.

Thanks - anything in particular - cam grind, rod length, piston type????

Is there an Argentinian website available I can look at - I've googled but not found anything

You can often wing it with a bit of guesswork and Babelfish or similar. There's a forum:

Just be warned that (like any forum?) you may be steered towards pretty full-on modifications. That said, you should get decent info on can type/duration for hot street usage or even a peppy cruiser.

as per 2v xle response - what do you wnat from the engine - torquie cruiser or wring its neck 7000rpm screamer?


auto or manual?

as a high rpm engine will need a hi stall torque converter for an auto or be riding the clutch for a manual in town

the 2v head was designed for the aust 250ci engine - i know the dish in the piston accommodates the CR ratio -but for the 188 you may need to skim a lot off the head to get decent comp ratio- effects rocker geometry+ head bolt length(maybe)

the 2v was designed in the early seventies and the inlet port sizes are relatively large ( for the valves 1.65" and 1.38") -

look at mikes aluminum head -it benfits from 30+ years of developemt has larger valves (1.75' and 1.5")and smaller inlet ports .

large ports (relative to valve size) tend to work at higher rpms - not lowdown.

so for a 250 ci (with larger cubic capacity) is ok - but for a 188ci - ie 1 litre less capacity i think the 2v might be too big for it and you might be pushed for lowdown torque( but Ok for hi rpm revs! )

not real sure but the hp of a 2v +188 would probably be similiar to std 250 ci with log head - but without the efortless torque

assuming you want a bit more for road cruising- personnally i would put the effort into finding a 221 (or a 250) - and put the 2v on that and have a nice cruiser

there are some 2v engines on ebay now .


as they say - unless you are limited by class capacity limits - ie racing etc - aint no substitute for capacity.

as addo aludes to- the mods to the 188 in argintina will probably be for full on race motors- and they use a differnt head ( ie not aust 2v) so maybe not directly translatable to an aust 2v head

Thanks Adam and Brett

The car's really for cruising but I still want it to sound like its got something under the bonnet. i do a lot of rod runs, so the 221 want me in order - it was my original plan :roll:

Cheers
Mark

twin 2" exhausts + extractors will give you the sound.

but yeah - the 221 will be the go -assuiming you aint going 250ci
