What's your budget, intended use or goal & what's it going in? For the money a set of AFR 205's are hard to beat.

Why don't you call up get a long block from coast if you're lost?

**Inkdcountryboy** · 04-05-2007, 12:28 AM

Want a fast street car for the track, mostly street racings, budget is set at between $4,000-$5,000. thats whats killing me at this point

**Inkdcountryboy** · 04-05-2007, 12:30 AM

Its going in my 1993 GT, the shortblocks dont come with the cams anyhow so im still in the dark with what to go with..

**Killercanary** · 04-05-2007, 09:53 AM

I and others have had GREAT success with our cams from Ed Curtis at:

http://www.flowtechinduction.com

My only suggestion is to wait and email him after you know for sure what you are doing with the shortblock and you know exactly what you want out of it in terms of performance, RPM range, and drive-ability. Ed's customer service is second to none once you are a customer of his. I can't say enough about him and the experiences I and my family have had with him.

**itow** · 04-05-2007, 10:12 AM

I too am using Ed for my latest build. Just sent my heads to him yesterday as a matter of fact..
Also, you can call Probe (Coast High Performance) and talk to the tech guys there, they are VERY helpful and VERY knowledgable and can help you figure out what you are wanting also. Talk to Eric in sales, SUPER nice and super smart guy.. He's their top guy. I will tell you, I bought my 427 dart block setup from them as an assembled short block, I normally do ALL of my checking, clearancing, and assembeling ALL myself and have my machine work all done at a place I know and trust well locally. But, Coast did all of that on this engine for me and actually, if I had to buy all of the parts seperately, and pay a machine shop to do the block work I would not have saved a dime and would had to have done all of the work myself! My point is, call Coast as your next step and see what they can do for you! Remember, stroker engines is ALL they do for a living and they are a multi million dollar company, so they know what they are doing!

BUY NICE OR BUY TWICE, the best deal isnt always the best route to take.

wish i coulda waited a little longer to swap suspension. i'd gone coilovers then.

**mlowry1260** · 04-05-2007, 10:48 AM

That's a pretty tight budget for a 351w swap. Although bigger is better, you may be better off with a 347 in this instance. Would you do the swap yourself? You'd better add up all the accesories you need for a 351 swap, it adds up quick.

Not sure if your referring to CHP's quality of parts, but if so, they are as straight up a company as you will deal with today. I have bought/built 4 engines with their parts and know countless others who have also with great luck..

It follows the common sense rule though of course.. You cant buy parts designed to make 400 horsepower and try to make 900 with them.. Cause they aint gonna live long if ya do!

Thats why I recommend him calling CHP and talking to Eric about what he wants to do.. Look at it like this, the probably sell more engine combo's in 1 month than ALL of us on this entire forum have built and will build in our lives put together, so, they DEFINITELY have the upper hand as far as knowledge, testing, and expierience goes!

**itow** · 04-05-2007, 12:29 PM

Inkd. Check out this thread on the Corral with for sale parts.. He has ALOT of decent SBF ford stuff at good prices.. $1500 for a set of AFR 205's with 2 dyno pulls on them. I dont think I'd drop $1000 on his short block setup, I still think putting $1500 to $2000 into your own 393 would be better for what you want.. But offer him $1300 or $1400 on the heads and I bet he takes it!

not at all, i jsut meant not to buy a 600$ stroker from ebay and try and make big power and expect it to live long, thats all.

Ah-hah! I TOTALLY agree! I have seen several of those Ebay stroker kits... I would stay away, FAR away from that kind of stuff. Sort of like how guys around me used to build "race motors" out of JC whitney kits when there stuff was TOTAL generic cheapo stuff.. Needless to say, they never lived long...

**Inkdcountryboy** · 04-05-2007, 04:07 PM

CHP told me that a 347 will make more power than a 393, be a better engine and i can go all forged in the 347 compared to the same money in just a forged pistoned 393

Well, there ya go! Like I said, they sell/build more engines than any of us so I'd listen to them over any of us! lol

Me personally, I suppose I'm just a hard head, but I (just me) would still do a 351 based engine but I would just save up untill I could afford to do it right (4340 crank and rods, good pistons, dart block, etc)

**Inkdcountryboy** · 04-05-2007, 04:22 PM

Yea but me and saving up dont work, money burns a hole in my pocket. if i could sell the 5.0 out of the car and one of my shotguns id go full bore on a motor, but id also like to do a tubeular k member and coil over's, theres just so much i wanna do and not enough money lol, once my shop gets more business it wont be a problem, but now im pinching to buy car stuff

Ahhh, ok.. Understood...
BUT, just remember the MAIN thing most people forget (I dont know you or your car so I am assuming your starting with a pretty stock setup)....
You cant JUST build a bad ass motor/trans combo and have a cool/fast car.. You need to upgrade EVERYTHING (brakes (no sense going fast if ya cant stop at the other end!), steering (what goods a fast car that wont turn/handle if your gonna drive on the street), suspension (better front and rear suspension is a must if you wanna drag race it), and MOST IMPORTANTLY the safety factor (roll bars, seats, harnesses, etc)...
Maybe think about all that stuff too and do some of that stuff first or along with the engine deal???
None of us build our cars overnight! LOL Heck, I've been over 6 years on mine and been through 3 different engine/trans combo's and probably only put 1000 miles on it the whole time! LOL

I'm gonna have to disagree with the 347 making more power than the 393 *if* both engines were maximized. No replacement for displacement. Perhaps finding a cylinder head that will maximize the c.i.d.'s the 393 possesses with take more money. And the 3.85" stroke in the 393 will most definitely offer increased mechanical advantage over the 3.4" stroke in the 47 *if* the 4.03" bore is chosen. Hypothetically, if both engines generated 1.75 FWHP per c.i.d. the 347 would make 607.25 and the 393 would produce 687.75.

Sort of like I said, I'd still go with the 351 based setup
