There are you times, you keep asking for but ignoring......no its not 1/4 but it still shows a big improvement from 350-383.

It seems to me that everyone is saying a 383 will make more power and WILL be faster assuming all other things are equal, but you won't believe anyone. You want me to find a stroker that runs faster than the 350 you mentioned? There many on the internet, I could go dig one up right now, but the main thing is running conditions, driver, and other mods that will separate the 350 times and the 383 times, that why some 350s are faster than 383s.

 

That is why I didn't buy 1000.00 dollar crank or 800.00 dollar rods or 520.00 dollar pistons. Like alot of people do on here.

 

I dont think no matter what anyone says, he is going to change his mind. He has already made up his mind that it is not better, and cant be proved. Myself, I deceided to go with a 396. I wanted the cubes and the stroker, so I did it. And I cant say I have any times, I am still assembling the moter.

 

I have made one pass on BFG dr's with a soft 2.0 short time, shifting at 6400 rpm's. I ran a 12.40@118, this is in a M6 that weighs 3555 on SS rims. I also have 100% stock suspension other than the fact that the car has Eibach lowering springs.

The car makes peak power at 6800 rpm's, so you tell me what you think is faster? This is on a prety tight budget build up with ported stock heads.

Oh yea one last thing, this was on a stock 3.42 rear end before the 12 bolt.

 

I built a 383 for a friend that has the stock top end, up to the cam. Yes this does kill some hp, but he didn't have enough money for the extras. Either way, this car went from running what.. 13.9's to probably low 13's. I can't say for sure exactly what it'll run b/c it spins the tires almost out to the 1/8th mile marker.. It ran 104mph with some improvement comming. If anyone wants to buy him a 12bolt, and some dragradials, We'll see what she can really do :-).

 

NO, strokers dont always run quicker, there are some 350's out there that will romp some 383's out there.

 

Was the 385 a stroked 350, or a destroked 400?

I have been racing five years. My car is slow my most peoples standards but I want it to be consistent as I bracket race. I also drive it to and from the track. When the stock bottom end went I had run a best of 12.71 at 107. We put the stroker short block in and ran 11's. I already had a 12 bolt, ET Streets, 700R4, 3600 stall, CNC Heads. The only major change was the shortblock.

To me the difference was really in the sixty foot times which dropped from 1.7's to 1.5's. The increase in torque was very significant.

 

Exactly. Torque is what motivates a car, and horsepower is merely torque over time. If you can gain a substantial amount of torque by essentially just swapping a crank, then you'd be a fool not to do it. No one is saying a 350 can't haul ***, but it's that much easier with stroker!

 

Peak power at 6800rpms so why'd you shift at 6400??? Just curious...

12scndz I believe the 377 is a destroked 400 but it's been a while since I looked it up...

 

Not in my case. Elected to maintain standard bore size with a 3.75" stroke crank. Felt the upcoming T-Trim Vortech would tax block integrity and wanted to have an overbore or two available in the future.

 

That's smart. I'm surprised more people don't do it. I have a spare block prepped and ready for if/when my 0.040" over combo splits a cylinder. Partially to prevent this scenario I did a partial block fill this year.

I have a question are you simply interested in the quickest et or fastest mph? The car is a whole combination which has been stated, but let's say you stay 355ci and you stated you want to run 10's you will have to spend money on more than just your engine to get there. You will still have to spend money on the proper suspension, rearend, the correct gearing for your rpm range and vehicle weight etc. It's like the old saying goes speed costs money how fast do you want to go? And for 10's you're going to spend plenty.
The other point I want to make is that the head and cam requirements will be different for each engine, heads/cam which are correct for a 355 will both be too small for a 383/396 so that needs to be stepped up as well. But if you are building from scratch I would go with the stroker everytime as well.

 

I'm Reminded of a great Statement:

"There's no REPLACEMENT for DISPLACEMENT"

More cubes equals more power. . . Bottom line! but you have to do it right! Call Nu-Tek they seem to have it all wrapped up!

 

there are some 1.8L v-tecs faster than big blocks.

no one is saying its the end all determinant as to which is faster here
