![]() Looking into new opportunity on 347 Dart block stroker...
Currently have an 8# S-trim TFS TW Stage-II heads / Stage-I cam, TFS intake all on a STOCK 35K mile motor (with girdle). Concerned about longevity of stock block making 400+rwhp in current tune. Been doing fine so far... Have opportunity to purchase a 347 Dart block with 4340 crank, 4340 I-beam 5.400", and pistons (yet TBD), at a really great price. QUESTIONS: ![]() ![]() ![]() ![]()

![]() If you have the necessary $3000 or so for a Dart block with machining, plus the rotating assembly on top of that, it's a great idea. Not only will you never be able to kill it around 500 rwhp, you can expand quite a lot in the future. Around the 400 mark you're still talking safe territory on a stock block. I'd be inclined to keep your car blown and select pistons to match, if the S trim hasn't died yet you'll probably still get a lot more life out of it (invincible Vortechs

![]() Well, I decided to pass on the motor.
Yeah, the price was right, but by the time I finish he motor, it would have been about $4500. Thtas just to get it where I am now... Then to ADD hp, it would have been another $2K. Sure, 600rwhp would have been nice, but at this time, I am gonna stick with my solid combo, and cross my fingers for 2004 one more time. ![]() Pretty isnt it... ![]() http://www.dariusrudis.com/mustang/n...e/img_0936.jpg

![]() A stock block with a girdle wouldn't worry me at all at 400hp. There's always the freaks that'll hold forever at 600hp...but I think even 500hp would be barely within reason. Dart blocks look bulletproof but they cost some serious coin. Plus with only 8#s of boost you're running it pretty safe. A Dart setup would be great if you cranked the boost way up, but for that money I say if it ain't broke don't fix it. I'd have stuck with your current combo, too.
