hey guys i was just wondering i have plans to build a 347 on my stock block....if/when it splits will the rotating assembly be damaged or destroyeed with it? or would i be able to transfer it with little machining to another block?

 

You wont know what was damaged untill it happens. You may be able to salvage some parts or maybe not.

 

if ur planning on making enough power to split the block just buy a dart/boss block now.

 

ya its just i have the money to do everyhting right now , but if i want to go with a dart then i will be set back a LONG TIME ahhhhh i hate bills

 

All the times I have seen the block split it took the crank with it.The worse that I have personally seen was afriend had a 347 that split the block and when it did the crank broke and threw the timing chain in the road. When that happened the valves met with the pistons and he had nothing but head castings, intake, and a carb. It even broke the main drive in the transmission and broke the distributor housing.

 

DAMN that sucks! good god that is like the worst case scenario....makes me want to fork it out for a dart block that i cant afford

 

He wasn't running much faster than me, the problem was he wasn't the easiest on the engine. It was a driver learning engine. In my opinion rpm was the killer of that engine. He had a solid roller in it and he would try and wind it to 6500-7000 with a T5. Syncronizers are at their limit at 6500, so he missedseveral gears with no rev-limiter.He tore out some main drive and clusters as well sending the poor engine into the rpm ozone. He is running a 408now using a World block. With the 347 he was running 11.60s N/A. Now he's running 9s N/A on pump gas.

 

thats pretty good times, do you know what the hp/trq was that he was running on the 347

 

yeah it might be a good idea to save for a stronger block

 

Screw the 347 go for the 351. Stronger and you can make more hp for cheap.
