You are watching: 350 bored 60 over cubic inches


OK..How perform I find the cubic inch of a motor the is bored .30 over and also .40 and also .60 over? What would a 350 boring .30? What around a 454 bored .60 over?

Well, the kinda helps...thanks...not too an excellent with bore and also stoke stuff, made a finest guess and also came out v a 350 boring .030 end is a 355?? sound right?BTW, Anyone understand what a 496 is? have the right to you just bore a 454 to make it a 496??

Just take her bore radius squared, times Pi, times stroke, times variety of cylinders. A 350 has actually a boring of 4.000, and also a punch of 3.480a 350 boring .030 over has actually a bore of 4.030.so bore radius would be 2.0152.015 squared = 4.060225 time Pi = 12.755573 times stroke = 44.389394 times 8 = 355.11515 If girlfriend don"t have Pi on your calaulator, it"s 3.1415927Rocky

Much easier formula come remember:Bore * boring * hit * .7854 * number of Cyls = Cu In4*4*3.48* .7854*8=349.849If you look at any calculator the 7854 space the height 4 buttons in a clockwise circle,,

496 is a .060" overbore 454 through a 4.25" stroked crank.A an excellent chea-, er, eh, inexpensive, "smallest the the large motors", imho!!pdq67Best vehicle Insurance | Auto protection Today | free Trade-In Quote

Much less complicated formula to remember:Bore * boring * stroke * .7854 * number of Cyls = Cu In4*4*3.48* .7854*8=349.849If friend look at any type of calculator the 7854 space the peak 4 buttons in a clockwise circle,,
One job i obtained bored throughout class and was looking v my warm rod publication so i saw that mathematics section....that .7854 kind of bugged me a little....but that is really simple how they acquired it Pi r^2 to then acquire the Diameter come be offered to leveling you division Pi by for and also then you have the right to just usage that brand-new factor so friend dont have to stress yourself to have actually to figure out the diameter...sorry i found it intresting....but climate again i"m in mathletes....Pat

ok hears the transaction i think i acquired a 327 or 283 i ran climate motor#,s in ~ mortecs it claims it can be either one yet heres the ??? as soon as i took the motor apart it had 60 end pistons in that what would the bore it is in on a 327 60 over same for a 283 60 over....i measured the piston holes and also came up through a 4inchs so im thinkin it has to be a 283 60 over to come approximately a 4inch bore have the right to some one help me figuar this out im confused...thanks. Heres part # off the motor...T0505s 3789817

ok hears the transaction i think i obtained a 327 or 283 i ran then motor#,s at mortecs it says it have the right to be either one however heres the ??? when i took the motor apart it had actually 60 end pistons in that what would certainly the bore it is in on a 327 60 over very same for a 283 60 over....i measured the piston holes and also came up v a 4inchs so im thinkin it needs to be a 283 60 over to come up to a 4inch bore have the right to some one help me figuar this the end im confused...thanks.

Looks like a sj 327 block 3789817How space you measuring the bore?http://www.nastyz28.com/sbchevy/sblock.html
i take it a tape measure up an measured throughout the piston holes and also it mirrors 4inches done the 60 end pistons that came out that the engine the same means showed the exact same thing 4inches therefore i acquired one that the brand-new pistons i obtained an measured the the same means came up with 4inches an it is a 60 end piston to..heres the component # because that the new pistons if it help L2166NF .060.... I allways believed a 350 ..or a 327 came Std is 4"bore so exactly how am ns comein up through 4inches with it 60 end plz help i know some around motors however this has me sittin back and thinkin.

i take it a tape measure up an measured throughout the piston holes and also it reflects 4inches excellent the 60 over pistons that came out the the motor the same means showed the very same thing 4inches therefore i acquired one the the brand-new pistons i gained an measured that the same way came up v 4inches an it is a 60 over piston to..heres the component # because that the brand-new pistons if it helps L2166NF .060.... Ns allways believed a 350 ..or a 327 come Std is 4"bore so exactly how am ns comein up through 4inches v it 60 end plz aid i understand some about motors but this has actually me sittin ago and thinkin.

=I very doubt both sets of pistons are significant wrong,,,What part of the piston are you trying to measure through a tape?& the is pretty difficult to measure a bore with any type of accuracy with a tape
so ns think i got ever before thing cleared up ...Piston, Forged, Dome Top, 4.060 in. Bore, 5/ 64 in., 5/ 64 in., 3/ 16 in. Ring Grooves, Chevy, 327, it is my new pistons had a an excellent friend come over that knows alot around motors had actually him inspect ever point for me he claimed i to be doin it wrong slaps me lol ...he excellent it and also came up v the bore gift 4.060 inches so ever thing need to work i hope he said it would ...thank you men for helpin me to glad i uncovered this plank to post on reason it has actually helped me alot again many thanks guys
