355/383 question

[jdhogg]

mornin all,im just curious why a 355 stroker kit is so much more then a 383 kit.also where can i get a good 355 kit

[big489]

his 355 stroker uses a 305 to do this parts for a 305 cost more because there not as popular with hot rodding.

make yourself a 383 you will be happier. there is no replacement for cubic displacement

[dr_bowtie]

when asking please post the brands you found and the sizes....IE bore size and stroke lenght...this may help answer the question better.... thanks

I'm curious, what are the bore and stroke of this "355 stroker"??

BORE= 3.795 (305 + .060)
STROKE= 3.750"
ROD LENGTH= 5.700"
ROD RATIO= 1.48
BLOCK HEIGHT= 9.001"
= 352ci


Guess this is how they get it

I came up with 339 cubic inches, maybe I used the wrong calculation.
Bore x Bore x stroke x .7854, is this correct or did I go wrong.

No you were right, I listed the stock stroke, try this

BORE= 3.795 (305 + .060)
STROKE= 3.885"
ROD LENGTH= 5.700"
ROD RATIO= 1.48
BLOCK HEIGHT= 9.001"
= 352ci



Thats what happens when I try an exercise the grey matter at 3am

my blazer has a 350 30 over with edlebrock carb, intake, and cam
it did a good job untill the head gasket gave out

but it keeps spewing oil out of the breathers
do i even need breathers?

i'm more of a body man then mechanic

Yeah, no kidding, a lot of work. I've heard of fellows stuffing a 4" crank in a small block, but I've never seen one. It's on the ragged edge to clearance a motor for the 3.750" stroke in some cases. And I don't know why anybody would want to bolt a 4.000" crank in a 305 block anyway. Sorta' like a pig wearing pearls.

3.736 x 4.000 = 350.79 cid
3.766 x 4.000 = 356.45 cid
3.796 x 4.000 = 362.15 cid

yup i agree but some people know better than the engine builders they want to do the work.
