AUDIOADDICT02 Posted July 19, 2012 Report Share Posted July 19, 2012 Ok, got another question for the engine builders on here: I recently pulled my block apart & noticed that the pistons have .030 stamped on them, correct me if I'm wrong, but I assume the block has already been bored 30 over.? If that's the case, boring it over another .030 will put me at .060 total making it a 472ci big block, would it be worth it in that case, or is .060 kinda pushing it?(ok, make that two questions) Quote CHECK OUT MY MYSPACE; SOME PAINT WORK I'VE DONE: http://www.myspace.c...customcreationz DODGE RAM 1500 QUAD CAB BOX BUILD: http://www.stevemead...showtopic=48978 DODGE RAM 1500 RUMBLEBEE EDITION CUSTOM ENCLOSURE: http://www.stevemead...showtopic=48983 PREFAB REMODELING: http://www.stevemead...box-remodeling/ G35 CUSTOM PAINTED L7 BOX: http://www.stevemead...om-painted-box/ CHEVY SINGLE CAB PAINTED SUB BOX/AMP RACK: http://www.stevemead...vy-boxamp-rack/ KICKER L512 BOX BUILT TO SPECS: http://www.stevemead...-kicker-l5-box/ RF HE2 10'S KERF PORTED BOX: http://www.stevemead...erf-ported-box/ 2 DC LEVEL 3 15'S KERF ENCLOSURE: http://www.stevemeadedesigns.com/board/topic/115502-kerf-ported-enclosure/ 2 HCCA 15'S PORTED ENCLOSURE: http://www.stevemeadedesigns.com/board/topic/129468-2-hcca-15s-enclosure/ Link to comment Share on other sites More sharing options...
crispy_chick3n Posted July 19, 2012 Report Share Posted July 19, 2012 what did it start out as? it really depends on the block. .060 over is the most i care to see, even then it still comes down to what you want to do with the motor. are you just rebuilding it and fixing something in the piston walls, or are you going to try and fully build the motor? fully built on a motor bored over .060 can get a little explody if you go too far. generally speaking .060 over is ok as long as you are gentle with it Quote This page is crispy_chick3n approved. © crispy_chick3n inc Link to comment Share on other sites More sharing options...

vettedude102 Posted July 19, 2012 Report Share Posted July 19, 2012 Yes, it would be .60 over but the more you bore it the hotter it'll get.

CleanSierra Posted July 19, 2012 Report Share Posted July 19, 2012 It depends on what year the block was produced in reference to how much you can take off before you start getting close to the cooling jackets. The mid 70's pickup truck engine blocks had a LOT OF meat on them and they can be punched .060 over all day long. A newer 454 SS type motor, NO WAY would I trust it. There is my $.02 Quote Im not the one you want to try to troll. Just a fyi for you. Link to comment Share on other sites More sharing options...
bassface Posted July 19, 2012 Report Share Posted July 19, 2012 (edited) 496 is .060 over with a 4.25 stroke crank. Very popular combo. http://www.superchevy.com/technical/engines_drivetrain/completebuilds_testing/sucp_0901_496_chevy_big_block_build/viewall.html Edited July 19, 2012 by bassface Quote Link to comment Share on other sites More sharing options...

bdog Posted July 19, 2012 Report Share Posted July 19, 2012 find out from a good engine builder what block you have because i have seen some rare big blocks that can be bored a 100 over and still be strong Quote REP Link to comment Share on other sites More sharing options...
WICK3DxGATA Posted July 19, 2012 Report Share Posted July 19, 2012 boring over 60 like most people said above it all depends on what the block is. i would say there are alot of big block that can handle 60 over but just check and make sure first.

b-dubs89 Posted July 19, 2012 Report Share Posted July 19, 2012 yes it sounds like your block has been bored all ready , i would ask a good machine shop or 2 or 3 just how far you can go with the block in question just to make sure things don't get too thin .
