I'm a bit concerned about what looks to be a casting flaw in that threaded hole in the pass side valley wall...

Yes sir there was a problem with the pipe threads on the inside lifter wall, we just drilled them out and tapped them to 1/2 NPT. the original size was 3/8NPT.

good/bad otherwise I hope you stick with us on this build. We've seen one guy years ago "promise" that he was going to make a iron block work and stated that there were a "few" running in dirt track cars although no proof was ever uncovered.... that never happened. We've lived Whitedart's he77 with his build (only running one that I know of....and BOY does it!!). Luckily he had a very qualified builder that saw it through. We had the aluminum "prototype" build that seemingly almost made it, but some failure set it back and iirc, life got in the way and it got shoved to the corner....or something. I wish you the best... there are A LOT of really good head packages out there needing a good foundation. I was so dangerously close to getting an iron Ritter block in 12.... but being I work at a dealer, a couple of guys REALLY leaned on my to go the R3 route so I did.

Ok I fixed the rear main oiling hole this evening not to bad just put the main cap in the mill and made a slot to the oil hole in the main line up with the oil pump feed hole.

Yes I will finish this engine, I am taking my time checking everything I can think of. If anyone sees something that there might be a question on please say something. I figure out some way to check it.

Having seen both of Whitedart's iron blocks machine work as delivered I have to say CHECK EVERY surface, bolt hole, treaded plug, etc.

Alot of things were not drilled/tapped streight, machined parallel or to size. Brad at QMP saved his block, most shops would have scrapped it.

Yours looks like a cool build, and I hope it all plays well for you.

"I have a set of W9's on my other R3 block (468 cid) with 59 deg lifter angle. That set of heads is a set of Chapman done heads and they are to small for that motor it gives up at 6800 but it pulls hard in the mid range.
This one is going to get the W9RP that Curtis Boggs from RFD did."

Curious, what kinda flow numbers does a Chapman W9RP have to choke off a 468ci at 6800? work


Reality check, that half the population is smarter then 50% of the people and it's a constantly contested fact.

The Heads on the 468 are standard W9's done by Champman, they flow in the 360 CFM range at .700 lift through the intake and throttle body. The minimum cross section on W9 heads is small in comparison to the W9RP's.

The heads that are going on this 420 cid motor are W9RP done by Curtis Boggs at RFD and they flow well over 425 CFM at .800 lift and continue to flow better up to 1" lift. The W9RP will not fit on the 59 deg motor because the rocker offset is not enough, the pushrod will hit the head.

Thanks for the information. I have assembled all of the heads, head studs and valve train the only thing I have not put on the motor yet is the clutch and bellhousing that will need to be indexed in, that is a standard thing I do on all of my motors, and the timing cover and water pump.

Thanks for all of the input on this build.

I'm more than happy to share any information that I have gained. I will say that these motors have a tendency to have oil drain back issues crankcase pressure going up kind of prevent oil from going down. I also drill through the china wall into the timing case area to help vent the crankcase I also enlarge the oil drain backs in the front and and back . And drilled for 1/8 holes cam tunnel

Are these blocks setup for a dry sump? sounds like
a dry sump would be a better way to go with the drain
back and pressure issues

Yes I agree that is why I drilled and tapped 4 of 1/2 NPT holes in the cam valley right next to the cam bearing main. To try and get the oil drain back to the crankcase. I also plan on putting my vacuum pump on the fuel pump plate in the timing cover. My logic is to make the crankcase lower pressure than the top end and kinda pull the oil and vapor through the holes and drain backs. Thanks for the input.

I think you are correct on this one, but since this is a street/race car in a stock chassis I don't have the room for a dry sump.

I have talked to some of the guys that have had problems with these blocks and so far most of the major problems were fixed when I got the block. There have been a few small things but nothing major.
Thanks

Mike,

The car is Clark's (Bad340Fish above). I am his dad, road flunky and navigator. We did not hang around long at Cordova, we wanted to beat the rain out of town.

This is going to be an epic thread, keep it going.

Thanks,
Bill

OK, since I am waiting on the new head gaskets to show up, I assembled the top end with all of the studs, heads, rockers and used gaskets,so far everything is fitting up nice.
