Fp black stock block
If it ****s on the dyno, it ****s on the dyno. That's a part of playing with cars, stuff is going to break. Atleast that's how I have learned to look at it, I don't get as upset when something gives. I'm going to be looking at around 550whp once I get the stock LICP and stock exhaust manifold swapped out for the one I have being made. I know I'm pushing the limits of about everything in the car at that point (ignition, transfer case, transmission, motor - everything that costs the big bucks... haha)
Why does everyone say "keep the tq under 400 and you'll be ok"?! There are TONS of people, including myself who make much more torque than that and are fine. I make 487 ft/lb at 5k rpm and this car is my daily driver, I drive it accordingly most of the time but I do some spirited driving quite often as well. And before anyone says anything, yes I'm on a stock short block, stock transfer case, and stock transmission
ive got a lot of cars in your power range tq wise running fine.
at the end of the day tho, you're on borrowed time.. the rods were not designed to withstand that kind of torque.. these engines were overly built.. pretty much why the 4g63 has such a strong reputation.
I to made over 400tq on a stock block but I also didn't beat the hell out of it. Most abuse was at the track. Its my dd and made sure it stayed together. Every time I floored it I was scared of something letting go though

Tom does a great job with his tunes. He can set the torque pretty much anywhere you want it to help protect the stock block.

Here in sweden we dont run more the 380 Torque on stock rods , to be shure not to break them
Its djust as crusedsm say, you will pop a rod if you run mutch torque on low revs , becuse you are helvely pusting the engine on low revs , if you have a laggy turbo u that spools lather the engine is alredy on the move , but that does still not make it safe , you will pop a rod att anytime , only all you may need i a bad missfire ,
I would never gamble on my engine i know how expensive a built motor is ,
its just stupid pushing the engine and pop a rod , bacause then you will stand there somewear on the middle of the road whit a blown enginge , and you will have a big hole in your wallet afterwards
I dont even wanna think what a new emty block , kosts and a new crank , and rods and pistons ,
that would be a nightmare ,
I have a personal rule , fore my self , I always make shure that I have some amount of money , in my wallet as the price that i bouth my car fore ,
Never push if you cant afford a rod to pop

mll.....we will get u going safely, u ever get ur tranny back? and as for the guy who said i should be making more power at 35 psi, yes i am....500whp at 420tq on stock cams....this winter i will have cams on the way with a o2 dump and some other wallet breakers hahaa....but once again op mll, my tuner has tuned many many many stock blocks as well with no problems, good to support a local guy as he is willing to help u fix any problems you have, heck he will even come to ur house! haha....
