gm block knowledge
alright i'm going to drop some gm block knowledge to u again and hopefuly this one will post..if u got any ? just ask and i will answer them to the best of my knowledge.i run old school small block stuff.but alot of what know can be used with any block.
gm performance parts made an olds rocket block.this block was made for dirt track racing and other forums where u can only use a small block.the rocket block has a raised cam and takes big block cam bearing,also the pan rails are wider then a std small block chevy.the wider rails and raised cam gives u clearence to run a larger stroke cranks.the can take a 3.8 inch stroke crank with no grinding and can take a 4.125 stroke crank with grinding to clear the rods on the block.these block can also be bored to 4.180 safely and come in a 4.000 bore.they where only sold in dry sump set up u would have to machine the block for an wetsump oil system and they use a oil filter not mounted of to the side of the block not on it.they could also be bought in tall deck forum or std and has splayed mains.this block could be bought with 2.65 400 mains or 2.45 350 mains
dart now owns the casting to this block and gm no longer makes them dart makes these blocks and they are the lil m blocks now
the rocket block takes specail parts such as pan,timing gear,oil system,cams.
gm performance parts also makes the bowtie blocks witch there is a big block and small block version.u can get these in 2 bolt main and splayed 4 bolt main forum.these blocks are now the strongest blocks that gm makes besides the drce block witch i will talk about next.the bowtie blocks come in many deck height for both bb and sb forum.the small blocks have std cam location and std pan and std small block parts can be used on these blocks.the sb can be bought with 400 mains or 350 mains also.they can be bought in with a 4.00 bore or a 4.125 bore..the 4.00 bore can go to 4.125 max bore white the 4.125 bore can go to 4.180.the bowtie bb takes the same parts as a std big block,u can get these blocks with std deck height or tall deck height.they come in diff bore sizes as well and take std big block main stuff and can be bought in 2 bolt or 4 bolt forum.
the sb2.2 bowtie block.is un like a reg bowtie block,these come with 58mm cam bearings,2.30 283 mains,and .875 big block lifter bores and come in a 4.115 bore
the olds drce block was designed for the nhra.this block takes a specail crankshaft,oil pan,heads.non of the std big block stuff will work on these blocks beside rods and some other stuff.they come with a 4.500 bore vs the std 4.250 bore as a reg big block.
gm made all these small blocks back in the day 283,302,305,307,327,350 and 400
if u got a 283,305 or 307 block toss it.its trash has a 3.875 bore.they dont make good power when built
62-67 327 blocks had 283 main sizes.they took cranks with a 2.30 main vs the std 2.45 main on small block.also they had 2.00 rod mains vs std 2.10 mains.these blocks can take power but not as much as the block i will talk about in a bit.
u can take a early style 327 block and drop a 283 crank in it to make a 302,when doing this u have to becareful because gm 283 cranks had diff counter weights on the crank so some cranks will clear but other 283 cranks the rod will hit the block.
the std bore for all the 302,307,327 and 350 is a 4.00 bore the 400 block come with a 4.125 bore std.and the std mains size on a 4.00 block is 2.45 vs a 400 2.65 main size.
when building a 4.00 bore block up the best blocks to be used are a 68-74 block.some of these blocks came with an 010 and 020 marking under the timeing cover this standed for 10% nickel and 20% tin.if u got a block with both of them stamped on the block the and its a 4 bolt main u got the strongest std block out there.the just 010 block is stronger then the just 020 block.now u can get these blocks as a 2 bolt main or 4 bolt.i prefor to get a 2 bolt main and convert it into a splayed 4 bolt main and fill it to the freeze plugs with block filler.when this is done and u use a 010 block the can be ran up around 850hp with out failer.but a std 4 bolt main block can go to around 725hp.with the right block prep.also u got to becareful that u dont get a scaluped block this is when gm tried saveing some cash and around the mains they are indented..u dont want one of these block in an all out race setup there good to 650hp or around so.these block can go to a 4.060 bore safely
when building a 4.125 bore or 400 block.these blocks came in 2 bolt and 4 bolt main setup just like above.the 010 an 020 thing goes for these 2 and the scaluped mains also.these block have weaker main webbings so when fully built with splayed main caps and filled i wont run them past 800hp with these blocks.they also got nickel added to the blocks the 509 and 511 have the most.these numbers are the block numbers.so the best one to use would be a 509,010,020 block converted to splayed 4 bolt mains.your probley wondering what a splayed main is.seeing how i said it so much now.this is when the outter 2 bolts go into the block at an angle instead of just up and down.also these blocks can be bores to a 4.165 bore safely after that u may hit the water jacket.
now remember when using these blocks in n/a,n2o,blower or turbo they all put diff amount of stress on the blocks..all the hp levels i said are in n/a forum.

Чрезвычайно почти все дамы соблазняются на собственный счет, считая себя страстными, фатальными, сексапильно симпатичными. Необыкновенно когда увлечены своим Саней либо Ваней. Почти все продолжают врать себя и в замужестве, необыкновенно попервоначалу.
Давайте обсудим одит интерестный , на мой взгляд момент. Точнее одну цитатку. Да кстате. Нашла очень даже не плохой видеоонлаин. Главное полезного много и без рекламы!!! Извените, отвлекаюсь, собственно говоря перейдем к самой выдетжке.

интересный нюанс. Когда я наливаю воду в чайник и ставлю кипятится, он начинает святится не естественным образом. Когда всёже вода начинает кипеть, чайник перестает светится и начинает подпрыгивать! Один раз он упрыгал даже в ванну. Подскажите как мне его починить.?
