Re: New block

Ford would cast blocks in lots which were fairly large lots. The castings would come out of the sand removal process and get stacked outside until they were moved to the machining center. I remember...

Re: New block

Even with the flaw that head will likely make some 4-banger fan happy. Some folks don't realize how many articles don't survive the manufacturing process. Even Ford had a separate machining facility...

Re: New block

Most rebuilders want a rebuildable core engine in exchange or they charge an additional core price. Good blocks don't grow on trees and why should they be the ones going out there scouring the...

Re: New block

I wouldn't be surprised if 308 CID engines have been fabricated using sleeves but I would wonder how well the heads would seal. You can only push that block so far before it would need a redesign for...

Re: New block

Scavenging helps draw in the intake charge before the exhaust valve closes so it's important that there is no interference in flow on either side of the equation. A divergent duct where flow it...

Re: New block

I'm not sure how the divergence in the exhaust ducting is going to affect things in there. The velocity decreases a bit until it gets to the port where it will speed back up again. This is where I...

Re: New block

It sounds like the porting flow would have less of a sharp turn to make so that might do well as long as it still leaves room for valve installation and adjustment in the tappet valley which it...

Re: New block

A lot of Jeeps were made during the war. The production figures are astronomical. Many Jeep types & derivatives made after the war too so it makes sense to manufacture a new one. Most of the old ones...

Re: New block

Folks had a completely different way of thinking back in that era. They were simply trying to make the best cars they could for the lowest amount of dollar value in order to get a price that would...

Re: New block

There are at least a half dozen builders just here in the states alone that could or should consider the ease of build of a new block. Shops like H&H, Roadrunner Engineering, and even Motor City...

Re: New block

If you have a casting in only a few months, you are truly dedicated to the task. Those who have started this in the last 10 or 15 years or so either never made it to the foundry or it took them years...

Re: New block

I'm thinking they holes are for hot water heater return. Most of the 8BA series had the return on the right side pump. Left side had the boss but was left unmachined.

Re: New block

I always figured the block would have to grow longer to get a non-siamese cylinder pairing internally. 3.375" was about as big a bore as they ever went with these blocks unless they started cutting...

Re: New block

I remember seeing one example of a "whole pan rail" girdle. It's been a while so I can't remember the details of whether it incorporated the caps or if it just surrounded them and augmented structure...

Re: New block

The The LB block was the first major departure from the first generation. There are no ports for water pumps in the block. There are just ports for inlet where the engine mounts bolt on and form the...

Re: New block

Yoyodyne
I have two usable 8BA blocks and one that's cracked but repairable. Both usable ones will need bore jobs with substantial cuts in both so I know what your stating there. It's always a big...

Some folks may have a large stash of old blocks and may never need one in their lifetime. Then there are the other folks that have to scour the country for a crusty old boat anchor to find it...

Re: New block

The rods are just stabilizers to keep the whole drive train from moving around under rapid torque loads. That closed drive rear axle will push the whole engine around if the mounts get worn or...

Re: New block

For the tappet bores, I'd imagine you would need a cutting head that could be fastened to a through shaft. It's doable but it might be tricky to get the finish bore. Might take several different tool...

Re: New block

All the blocks have the same basic profile at the rear with the exception of the half bell on earlier engines. Even the 8BA block has enough casting there but it's just not drilled for the rods. Keep...

Re: New block

Ford had a very odd oiling system for the 85/95/100 HP V8 engines but it wasn't all that out of place during that era. Where the oil pump pressure port interface is up in the bottom of the block,...
