I have a 1993 GT. What say you as far as a new motor goes. Its not a daily driver. Week ends and 2 time's to So Cal a year. I want smog legal and streetable. It currently has a 302 with a vortech S trim, 30 LB injectors 70mm t body. Thanks for reading.

347 based on a good block, not a stock block.
keep it on the "smog legal" fence.

Once you go with a 347, you will never again be able to go back to a lower stroke. There is no way to describe the blast you will get out of the torque produced by a 347 stroker motor. You can't beat a 347. It will ruin all other motors for you.

You could even go with a 331 but might as well get some extra cubes and get a 347. I think whatever you do don't get a 306, not really enough power difference to be worth it.

Keep in mind, when going to a 347 it uses a 28oz balance so you will need to replace things like the balancer. A 331 uses the same 50oz balance so you won't have to replace anything more.

Thats new info to me since I run 28 on my 331.

When I ordered my kits I had to specify balance and rear main seal configuration.
You can also get internally balanced but that is big money, usually.

why not drop a 351 windsor in there?

Some guys like small blocks. I'm one of them. Small blocks are lighter than big blocks and when bored and stroked, a 347 can make more power than a 351. Fits better too.

Cool. Who would you reccomend? Would I still be able to use the S trim, or would I need it? My car is a five speed, the stock T-5, will I need to swap that out as well? Would it be smogable?

I run a Vortech SQ-trim at 12psi in my 93 Cobra with a 347, never had any problems and I've been running that setup for years. I have the original stock T-5 and it works fine.
Regarding choices of 347 motors, I'm sure a lot of people will have recommendations. I've had 2 347 motors custom built, and I will never go that road again. Too many problems with the build and the builders don't back up their work when you have too many problems. I'll go with a crate motor next time and be sure to get a warranty.

Buddy of mine runs a 50 on his 331? Maybe I'm wrong? Just go by what I've seen, that's why I always encourage people to get other opinions/input besides mine. ![[Smile]](smile.gif)
Now I have to go on a mission of reading and web searching lol. Thanks for settin' me straight! ![[patriot]](graemlins/patriot.gif)

Not to bag on you, you have a beautiful garage!, but a 351 windsor is a small block.
Even a stroked 351 (408) is still a small block.
I dont think you are speaking of a windsor motor.
..just FYI not trying to be a know it all punk.

Sure, if you build the motor to be blower friendly. I think you will probably have serious traction issue with that setup. If you want to stick with the blower consider a 331. You will be able to make plenty of power with that motor and an S-trim.

If You are staying with a stock block then Why would You want a stroker with a S trim? 306 makes enough power to break a stock block. I have 306 with S trim & stockblock with around 600 fwhp and all I can say is it's a ticking time bomb! If You are going stroked and blown then You have to at least go with a sportsman block IMO. It would suck to drop 3-4k on a stroker and blow it up rite after.

BillyBlownEngineNOSMustang, sorry to hear about your engine! An aluminum block?!!???! Big dollars, dude! Rare as can be, also. Look into doing the Ford Boss block, that's what I would do. Marcy must REALLY love you a LOT to shell out that kind of cash!
Good luck,
Lems

You can get a Ford B50, an SVO, or a DART block. Those are arranged in price also from lowest to most expensive being the DART block which is rated at 1100+ hp but has handled much more.
An aluminum 4-bolt block costs around $4,200 un-machined. Add in machining, torque-honing, rotating assembly, balancing, misc new screws (ARP), and gaskets and it easily adds up..
BOTTOM LINE: The more HP you want, the more you have to spend!

I will go with a World block (Man O War) seems to be pretty strong. As well as expanable. As far as motor size goes. Thanks for all your input. It has helped.
