Yeah it bothers me also. My brother in law had a 68 fastback that he had the towers taken out to get a pro touring suspension done. He had a stroked 351/459 I believe. It was done beautifully and when he was done he sold it to one of his rich buddies for alot of money. Just cant bring myself to do it.

I just got the heads back from heat treat a couple days ago.  This week I'm working on getting the fixture machined; plan on machining the heads next week.  I will post some pictures as I get into machining the heads - Jay

Jay, a thought just crossed my mind while reviewing the comments here. When you have a head capable of helping create in excess of 1K HP in a normally-aspirated configuration, you are getting into a range where the block is the 'weak-link'. Have you given any thought to what might be an answer to the problem?

(I discussed that very topic with Jim Dove in days past, and he had some ideas and I had some ideas...)

What say you?

Ken, I think an aftermarket block with a Cometic head gasket ought to hold 1200 naturally aspirated HP with the normal head studs and 15:1 pistons.  More head bolts would be better, of course, and I've thought about adding two more head bolt locations to each cylinder on my heads, like the aftermarket LS engines, but unless the block has bosses that you can bolt to, that wouldn't do any good.  Maybe when I do my block... ;D

Back in the day my Uncle raced a lot of bowtie stuff. The blocks we were using were surplus industrial blocks because he got a truck load of them for less than what one aftermarket would cost. I think he was running Chief heads with the extra bolts on the valley side. It was kind of a pain, but we spot faced the valley and bolted blocks in there to take the extra stud. At one time there was even a "kit" to do that before the big companies changed their castings to accommodate the extra stud. Of course the kit was not designed for those industrial blocks so I had to make some fixturing anyway.

I don't know if it would make a significant enough difference on an FE to warrant the hassle. Or if it's even practically feasible without a resigned block.

Is the issue the heads blowing off a NA engine, or the BLOCK blowing apart?

Thickwalled IRON (nodular?) block that isn't bored to extremes, 4.00, 4.05.  Cam tunnel strengthened, or at least not weakened, 6 crossbolts (Shelby design, but it's aluminum :-( ), 4 crossbolts, girdle, fill (but what is the lifespan of the fill material?). 

Other than pouring nodular iron into a Shelby block mold, what else can be done?  Some sort of through-bolting top to bottom, side to side?

Outside-the-block fill.
Encase the whole engine in a solid concrete block.
A little weighty but if you set it back, weight distribution should be ok.
