Lets talk blocks......

I heard some of you guys were using a stock block on your turbo setup. I am using a SVO sportsman 2 bolt main block and after 6 passes I have eaten all the main bearings out of it. It didn't shift my last pass so I reached down and shifted it well the log said 8100 rpm. When I was loading it up I heard a squeal so I pulled it and noticed the bearings.

not sure how hard you are leaning on it, but sounds like an oil issue to me.

estimated roughly by mph and weight 1100-1200 hp

what kind of crank?

My buddy Clifton went 5.40's on a stock 1972 (or some such) 351 truck block. He had good pistons and rods in it. Stock crank and block.

If memory serves correct he put down around 900 maybe a bit more at the wheels.

Your car is capable of making a lot more power than Cliftons car did back then. Shit can the stock block.

I got another block, I am just wondering what some of you FW guys were doing. I only made 6 passes, I just dont want to spend any more money on the car this season, it would be nice to actually race it

It was d.s.s piston, eagle rods and stock crank, block F4TE. I have his old pistons and rods

I can tell you this much..the only time he spun a bearing was doing a 1/4 mile pass and he over revved the motor. He took it past 8,000 on accident.

The only other motor carnage was when he dropped a valve but that was of course no fault of the motor. He is running a Pro Comp block now and has had no problems with it. He didn't even pull the motor apart after rolling the car 85 times at Kennedale a couple years back.

Yes I know...I see they are treating you very well!

It is but I'm no where near what he ran. Maybe with bigger turbo it will

could also have alot to due with the state of tune up, and set up of the crank.
