: Better choice 355 or 383?

I don't plan on racing just having a bit more fun, they wouldn't be forged either. Just wondering what would be the better route and why?

Can't beat cubic inches,
If you are doing a FULL rebuild it only costs $250 more for the stroker crank to make it a 383

:iagree: There's no replacement for displacement:thumbsup3:

I agree, 383= more torque

Just keep in mind those cranks linked to are for 2 piece rear main, if you have a roller block 87+ you need a 1 piece rear main crank. And of course more if you want a forged crank.

I would post links but I haven't been here long enough...

If you compare the pricing on complete rotating assemblies there is less than $50 difference between a 355 ( 30 over 350 ) and a 383 kit so why wouldn't you build a 383 .
$50 extra maybe for crank clearancing work in bottom of block

the difference in performance is worth a lot more than the few bucks in parts

it is said there is no replacement for displacement. If some is good, more is better, and too much is just enough.

RACE ON!!!

Torque and cubes.
Once you own a 383, you will never again build a 350.

I know a handful of people that went with the 383 and love it. Great power jump!

:iagree: BUT...If you get the right cam package displacement does not matter...We had a 355 in a dirt sprint car that was killing the 410's...It was always fun making those guys mad. Engine builder said it was all in the cam. He had some sort of special grind that he said he would take to his grave...

God love John Lingenfelter...RIP

383's are the only way to go with given the choice of this or a 355ci

Pure physics;
a bigger engine has the potential to make more power with the right cam and be more streetable doing so.
2.4L F1 engines make a million HP but need to rev to 18K and idle at ???

it is never true that displacement doesn't matter. If the guys with the 410s had the right cam package, the 355 wouldn't have had a chance against the 41os.

Race on!!!

Summit has an Eagle brand crank for the 383 right now for 169.99 but you also have to consider new pistons(Regardless of 350 or 383) but also you have to have the block and stock rods machined a little for the longer stroke and then with a 400 crank you have to add a external ballancer on the front and on the flywheel. All in all though its only a 3-400 more to go 383 vs. 350. Only know cause we have looked into for the last couple days but havnt decided to do it yet.

You can buy a rotating assembies that use the 2 pce internal balance setup ( neutral balancer/ flexplate ) or to suit the later 1 pce seal ext balance at rear setup

The cheapest stroker kits basically use a 400 crank casting with journals cut down to 350 size so they retain the 400 balance setup ( ext both ends) .
The better ( more $$$ ) kits can be had with stock style balance to use original parts ( neutral balancer)
My 383 ,based on a 4 bolt '00 Vortec block ( 1 pce seal ) has stock balance; ext at rear and neutral at front.
In any case, if you have to run the 8" 400 balancer ,it is only a matter of a slight adjustment to the X member with suitable hammer to gain the clearance needed
