Ive got a stock 302 in my 94 GT, ive got about 3k saved and will be able to get another 3k around the summer time. I was thinking either building a 347 stroker with AFR 185's, trickflow track heat manifold, and ed curtis cam. But then I got to thinking about maybe building a 306 with AFR 165's, ed curtis cam, trickflow track heat manifold, then slapping a vortech S-trim on there. Granted it will be more money, and i would just be running the 306 N/A for 6 months to a year, do you think it would be a better idea? How much less power would I bet getting out of the 306 with 165's compared to the 347 with 185's? Also, do you think a stofck bottom end with 117k Miles could take that set up with 6 PSI of boost once the top end is completely rebuilt? Ive replaced the front and rear main seals and she doesnt burn much oil. If she would take it, how long do you think it would be before something broke in the bottom end? Also, any other way you guys would go with this, different components? Maybe a juiced 331? I dunno, still tryin to lay down a gameplan for the upcoming build, because that money sure is burning a hole in my wallet!
Boost Vs. Ci's?

i'm with paul. Slap an S-trim on the stock motor (make more than an n/a 306 obviously, plus it'll have reliability), and in the meantime buy a block (preferably a dart) and start setting up to do a killer 351 stroker combo with a big blower (upgrade the S-trim to a T or Ysi) or if you like, make it a high compression n/a combo.
By doing it this way you get to enjoy some good power while waiting for your other stuff is ready and you get to have everything spec'd exactly as you want. .

There's no replacement for displacement... :dunno: :boink:
Ever heard... "How fast do you want to spend" it's all true... you can be as fast as you want, but it's going to cost money, no matter what, Big Cubes, or Lots of Boost...

Nobody said its gonna be cheap or even close to being inexpensive.
At that level its a matter of deciding what you want and then choosing a path to to getting there.
Paul and I have just offered more efficient ways of getting what he says he wants. Because building a big power adder combo on a stock block just doesn't make sense especially when he has that kind of money in his pocket right now.
Throw a blower on, keep it sensible as far as tuning, boost and RPMs go, then take a little more money and start piecing together a dream motor that will handle anything you throw at it and when the stocker shits the bed, you've got a new one at the ready. or maybe even take it out and sell it... might be able to get a couple hundred bucks for it.
I should have said that the car is a Daily Driver and that I need to keep it atleast reasonably streetable, so im looking for a max of say 450hp, thats my goal atleast. I like the idea of just slapping on the blower now and building the motor seperatly, but how long do you think my engine will last with 6 Psi of boost? Because it would suck to have the thing go south before the new engine is ready and be out of a ride till I can get the $. With that idea I was thinking possibly buying a stock block off of craigs or ebay, putting in a 306 or 347 forged rotating assembly and then just transferring the rest over from the current engine. That why I was thinking maybe 165's so I would have to notch the stock pistons or mess with the bottom end at all. Plus it seems like 450HP would be reasonable with the set up ive got in mind, right?
stock block
DSS forged 306 or 347 rotating assembly
AFR 165's
Vortech S-trim at 6 Psi
Trickflow Trackheat manifold
FRPP 70mm TB
BBK Equal Length Shorties
UPR catted X (exhaust is because of California emissions laws)
Do you guys that setup would make 400-450 HP?
Also, how much do you think that setup would make on a stock bottom end, minus the rotating assembly of course.

That is a great setup.
Flar said:
Easily. That will probably put you at 450-475 RWHP depending on how conservative the tune is.
Here is a combo for reference...
Pro-M 80mm MAF
70mm TB
GT40 Intake (tubular)
AFR 165's
1.6 Rockers
Anderson Ford Motorsport B31 Cam
FRPP Shorty Headers
Vortech S-trim (3.33 Pulley)
498 RWHP :coolsmiley:
Alright, that sounds awsome. Im gona order the Vortech soon but im going to wait untill I get my tax returns back and sell my other car, then all buy the vortech, AFR 165's, and an intake manifold. There was a guy on craigslist selling a 90MM MAF from a lighting for 75 bucks, you guys think I should pick it up?
About the maf, you can if you want too. Those are good mafs. I see them brand new everywhere for 90 I think ebay even has some for that or at least in the 80s.
Are you going to run the FMU :crazy2: or buy bigger injectors? On ebay you can get that maf and 42# injectors for $450 which is a lot but a good combo.
