Hi all,
I'm new here,so excuse me if this has already been posted.
I've got a 68 California special and am considering resting the 289 and replacing it with something a little more powerful.
I'm after a streetable/driveable engine without wanting to break the bank if not necessary for my needs.
From those with more experience, is a 351w a good upgrade choice over the 347 stroker? Any other input would be appreciated.
-
Hi, I've always liked the CS,
331,347, lighter, which is better for your front end, and car balance
-
What do you think of crate engines? Or can anyone in the forum recommend an engine builder whose credible ?

Fataz Competition Engines are regularly recommended on here, particularly by people who know what they're talking about.
Crate engines are pretty hit and miss by the sounds of it. Sometimes you get lucky and get a good one.

So 347 is great combo, particularly if your early block is ok as they are stronger then the later 302 block, a good 347 will make mid 400hp and be perfectly street-able. The rotating assemble is lighter then a 351 and the mains bearings are smaller so less heat and friction than a 351. 351 is bigger heavier and stronger but I wouldn't consider one unless going to a 408 stroker. You could make a 347 look almost stock in the bay. Talk to Ian Woodward at Fataz racing in Brisbane tell him Shaun sent you. Or if you want talk about what to build I'm happy talk about options. Boofhead on this forum has 347 kit for sale as it happens.
below is my 347, which is likely more than you need, you could get away with cheaper heads depending on the HP you want

The 347 is a good option and is a good choice for your mustang . Your model mustang only comes with the small Windsor so you could make it look std looking if that's what your after or look like a hi performance engine also . My 66 has a 347 that to the untrained eye looks stock except the dizzy and extractors ,and that's the way I want it .. It depends on the HP you want also ? A nice 347 could be 400 to 470 HP but if you go a 351 stroker to a 408 your looking at 450HP to 550 HP . Either way your auto trans will need an upgrade and the diff centre and exhaust system . It s a catch 22 when getting more HP ,it doesn't stop at the engine . Your old 289 might have around 200 HP so you might be happy with 350 ish HP :shrug:
-
Unless your after more than 500hp the 347 is the best engine. Otherwise a 351 stoked to 408 is the go. I would personably never build a plain 351w performance engine as a 347 will be better in all areas.
I do have a 347 kit plus cam plus heads I was going to build for my mustang but change of circumstances so willing to sell it off. PM if serious.

Sounds good,thanks for the info...I didn't know about the block strength. Has boofhead got the kit advertised on another forum? Sorry I'm new to the whole forum thing,so need a bit of direction.
Fataz seems to be the common recommendation,so I'll go with them by the sounds of it

Sorry boofhead,only just read this after I sent.

I have not officially advertised it at all. Just mentioned it - Shaunp and I have build engines and played with cars together. We are friends.

Yep Talk to Woody I know him well, they build not only street engines but much of the business is propper race engines.
-
So if I use my standard block,no need to change headers ? Will the 4 speed need anything more than a stronger clutch?
-
Header change ,depends on what you have . If your going to build a 347 that's great but what HP are you chasing ? Mild to wild ? You did say just some more HP . Your top loader will be fine but yes the clutch might be a problem . With a good HP increase you will spin one wheel unless you fit a true trac diff . My 347 is around 430 HP at best and that's plenty on the street .
-
What headers do you have now is the question. You would balance it with a new clutch anyway

I'd be going for a mild setup, not chasing crazy hp

Not sure,I'll take a look

mild 347 is twice what you have now.

Exactly shaunp, and it gives me a decent base to improve on

You'll be surprised how quick they are, with the right diff an average 347 is a 12 sec 1/4 car, a better one is and 11 sec car, so you can scare Clubsports with them pretty easy.
-
Your car being a manual ( factory) your diff ratio might be ok . Might be a 3.00 :1 ratio or even a 3.25 type ratio . Do you know what it is ? . Going from around 200 HP to around 400 HP will put a smile on your dial :grin: .

It was actually an auto converted to 4 speed top loader with a 9" diff,
Only got the car delivered last week so will have to check out the ratio
-
Ok you need to check that out because that is a huge factor . What part of the coast you in ?
-
Broadbeach waters, I've got the car at my mechanics at the moment as I'm overseas...still havent even sat in it...can't wait to get back

Your model mustang only comes with the small Windsor so you could make it look std looking if that's what your after or look like a hi performance engine
The only engine that wasn't on the books was the 427...
-
Pinto Pete really ,I didn't know the CS had so many engine options . I thought they were all small blocks . I must admit I don't know a lot about the California Special mustangs .
-
You could pretty much order whatever spec combo you desired for the model...however the majority ended up being 289s
-
I suppose I haven't taken much notice of the CS mustangs and to be honest all the ones I have seen were all small windsors and no big blocks . You learn something new every day hey :grin:

I didn't know much about them either until I bought one lol

One of the members on here had a big block one... :thumb:

Bumblebee's red CS has a factory 390 in it, it was at the Nationals last year,

you could get a 390 as well as a 2 or 4 barrel small block.
he only way to know if it is a real cal special is to have the orig paperwork or get a marti report or ford report.
if you want it to look stock you need to use iron heads and an iron intake . you can get decent performing iron heads but the iron intake will limit power.

Luckily I got both original paperwork and marti report...I was originally going to put the stock engine to the side and use a later model roller 302 block as the base... but a few of the members have steered me towards using the old block
-
Hmm old block I don't know ,they are a little stronger but your not building a big HP engine or revving it's :shrug: :cool: off . Doing your old engine might be opening a can of worms .
-
Do you suggest going for a later model roller?
-
You can ask the experts on here . But here's my thoughts . A good late model roller engine ,leave it and don't stroke it ,because your not after a high HP engine . 350 HP ish I would think will be plenty . 670 street avenger Holley carb , edelbrock RPM air gap intake ,good alloy heads like trick flow or AFR ,good Hyd roller cam etc , MSD dizzy etc ,double row timing chain set ,extractors and twin 2.5 exhaust . A 302 will rev easy to 6000 and more if wanted . You may not have to rebuild the bottom end with these late engines if it hasn't done a million Klms . Your old block may or may not be able to be borded out and the water jackets might be in bad condition . I've seen plenty of old block that are junk . Wait till the others have their say about it .

it all comes down to what you really want and how much money you have.
both early and late blocks are fine with 400 hp or so.
if your current engine runs perfectly and you want to put it bavk to stock someday, it might make more sense in your articular case if you get another core to build if you have a place to store your other engine etc.
-
revving it's tits off .
ummm...and just where are the "tits" on an engine? :lmao:
-
With the late model engine it's already a roller block / cam engine and are a very good engine . With the right mods it can get 1.2 HP per cu.inch ,so 350 plus HP no problems . If you wanted a stock looking engine like mine , go stock air leaner modified a little ,a edelbrock RPM intake with a 1/2 inch open spacer ,then grind the markings off it and then paint it blue . Do the same with the alloy heads and a stock looking dizzy and have people scratching their heads wondering why it goes so well :lmao: . You must check the diff ratio and you must change the ratio if it's a 3.0 -2.8 or so .
-

My view is do the old engine - better base and is legal for your car. It can be argued (and has been by most RTAs) late model engine is not due to pollution control laws unless totally original including efi and ecu.
If you find the early block is done then look at alternatives (such as a dart block).
Note: Roller cam is no issue in an early block - I always use linked bar lifters regardless of the block.
