stroke from 350 to 383...good idea?
i was looking at the stage 1 stroker kit from excessive performance
i was wandering how much hp those things make...they say they can handel 550hp...
im thinking about just stroking it out to 383 after i do the full exhaust and gears, and i will just skip the cam and get it later..
and after the cam i will put in a 100 shot in it
and call it quits

Well a stroker isnt gonna make much more hp than your 350 if you dont do heads and cam.....heads and cam is where the hp is. You need to do the total package if your gonna do it IMO. Do it right the first time.

Opinions vary on this one....Do a search for strokers.
Personally, I'd never build a stroker. Many of the quickest LT1 cars in the country are 355 cars. I've got a buddy with a 2 bolt main 355 with a stock crank thats running 10.35...With only a 150 shot. The car's been 11.4 on the motor. This thing has pulled a 1.43 60 ft. time!
Think about where you want to build HP, and torque. Yes, strokers are torque monsters....BUT....Torque blows the tires off when you try to launch it.

i've yet to hear a good argument for not stroking other than
"well my friend has a fast 355!"
(or obvious limititions in your racing class)
longer stroke- more vacuum, sucks in more air
you need to get more of a top end cam than you would in a 350 to get power up top, duh. you act like a 383 wont make power up top. it is in no way more limited to making power up top than a 355. hell it has an advantage. more stroke.
obviously if you put a cam in a 383 designed for a 355, its going to have the powerband pulled down some.
you rednecks from the souph are so stubborn

The easiest way to make more power at all rpms is to increase the displacement. Whatever a 350 can do, the 383 can do better. As Trey pointed out, people with less than optimal top end horsepower from their 383 do not have the correct heads and cam to do the job.

HAHAHAH.......It's usually the guys who can't afford or who didn't do the stroker that says the 355's are "some of the fastest." I have never heard of a guys who builds his motor right that says.."I wish I went with a 355 instead of my stroker." The key is...like TREY said, need the cam and some good flowing heads. Then you're there!

Now again....Show me all the N/A stroker LT1's in the 9's....
