Looks like camshaft and lifters are ok and pushrods and roller rockers too. Crankshaft has to be measured and possibly #1 and #5 rod journal have to be grind to undersize 2.100. Other journals might be ok with only polishing. So, we only need one block machined, heads fitted with larger valves, one new piston and two connecting rods to build a new engine. And oil pump and shaft ...

We were preparing our dragster today for the next event on coming saturday and with Jyrki's old normally aspirated engine. Some problems occurred during the cam break in as the distributor gear pin was broken and we didn't realize that before the engine warmed up and started running badly. The gear spinned over the axle and ignition advance got screwed! That breakage happened at the last race where our turbo engine destroyed.

So, tomorrow we will install a new pin and do some more tuning and then go for the hunt of high 10's or low 11's .

16 ladder elimination today and Jyrki took a red light at semi final and we lost to Janne Noren's Chevy powered '34 Ford! 11.859 / 175,69 was best the normally aspirated Y could do with non ported heads and about 10.4 to 1 compression. Seven runs this weekend and three 0.001 sec reactions. All runs in 11.859 to 12.004 range and all top speeds within 173 to 176 km/h! One race weekend to go this year...

And a short video about one 11.9 second run. Doesn't even lift the wheel without turbos . And that steering does some strange moves when turning... Whoops! 60 ft times were around 1.6 seconds.

That is a huge turbo sticking out of the orange chevyII, and does the blue mopar run 8.0's, Nice looking top quality cars. Looks like it was quite a show. Hope you get your turbo engine back together soon. Any plans to get the kids a JR dragster?

Sorry to hear that Hollow heads lost their engine block.. However, have followed their exploits here & in Y-Block magazine for some time. Sorry, but I'm not surprised, as I think they have been expecting to much. This is a case of to much Turbo charging & not enough time & money spent on the engine under the turbos...

I'm not sure what they did to the bottom end but it was pretty stout. If it didn't have a girdle and reworked caps/bolts it probably will soon. They are far below their fastest, more is yet to come.

Are you following the super horsepower twin turbo pickup on the forum? I'm still waiting for it to over test its bottom end. Chuck

Y's guys rule!
Looking for McCullouch VS57 brackets and parts. Also looking for 28 Chrysler series 72 parts. And early Hemi parts.

Paul, you are right about money spent. With more money and time we could have gone to dyno more often, but it takes 500 euros each time.

Chuck, you are right about that bottom end. It really is stout and can handle a lot torque and horsepower if balanced right. Even with stock bolts. Don't remember if Hutz is using ARP stud in his engine, but we had stocks. And that our mishap did'n come from bottom end...

And, about our expectations... Sure, we expect a lot but we still are sure we will do it. It's just to get all things together and working right. Going fast isn't easy or cheap, but it's fun! Is there really any point to stick with carbs and without boost .
